Does a Medium Roast have more caffeine than a Dark Roast?

Because coffee roasting only slightly reduces the quantity of caffeine in the bean, the caffeine level of a light roast, medium roast, and dark roast will be indistinguishable from one another. There are myths about both light and dark roasts, with some stating light roasts contain more caffeine (which is only marginally accurate), and others claiming dark roasts contain more caffeine (which is likely due to a more developed “coffee” flavor), but good old science comes to the rescue here: Caffeine did not degrade significantly, with just 5.4 percent of its potency being lost after being subjected to extreme roasting.

Source Green coffee loses anywhere from 10% to 20% of its weight during the roasting process due to evaporation of water, hence darker roasts may or may not have a minor advantage in caffeine content when comparing exact weights after roasting.

Does Robusta have more caffeine than Arabica coffee?

Robusta has nearly double the amount of caffeine found in arabica, according to a conventional rule of thumb. If you are comparing arabicabeans to robustabeans, the results will differ based on which arabicabeans you are comparing them to. A chemical analysis of materials submitted to a lab will be the only method to determine this for certain.

How Much Caffeine in a Cup of Coffee

Although the earliest coffee shops were established in Istanbul, Damascus, and Syria as early as 1530, it was not until 1819 that a German scientist called Friedlieb Runge was able to extract caffeine. The caffeine found in nature acts as a natural insecticide, assisting plants in their defense against predators such as dangerous insects. When caffeine is eaten, it causes an increase in alertness and energy due to its capacity to imitate adenosine, a chemical that attaches to the adenosine receptors in the brain.

The upshot of this is that actual adenosine is prevented from doing its role of causing sleepiness and causing nerve impulses to slow down, as a result of the blockage.

  • A conventional 43-gram Hershey’s Milk Chocolate bar includes approximately 10 milligrams of caffeine
  • A typical cup ofDecaffeinated Coffeecontaining around 7 ounces will likely have approximately 10 milligrams of caffeine
  • And a cup of Teacontaining approximately 10 milligrams of caffeine. A 6 ounce cup of black tea will likely have around 50 milligrams of caffeine, whereas a 6 ounce cup of green tea will likely contain approximately 30 milligrams of caffeine

Caffeine Impact on Health

Coffee has just a minor effect on the body in general, and moderate doses do not produce the issues associated with excessive caffeine use. Caffeine, on the other hand, is inversely associated with all-cause morality: This suggests that people who drink coffee have a reduced risk of dying in a given year than people who do not drink coffee. Although the specific mechanism (antioxidants, lifestyle variables, or increased alertness) is uncertain, the general agreement is that drinking coffee is beneficial to one’s health.

You might also experiment with decaffeinated coffee.

When utilizing the French Press brewing technique with strong coffee beans, one cup of coffee can contain significantly more caffeine than a cup of coffee that has been mildly brewed, therefore you may want to experiment with using less grinds when preparing your coffee.

Caffeine is metabolized by the body’s liver once it has been taken, and it is absorbed by the stomach and small intestine in less than an hour, following which it spreads throughout the body’s tissues.

Caffeine in Single Origin Coffee Beans

If you want to create a significant change in the caffeine level of a mix, you should use Robusta beans rather than experimenting with different forms of Arabica. However, the mix should not be decided by how much caffeine can be squeezed out of it – flavor will always take precedence over caffeine content.

Some Caffeine Stats

Caffeine has the chemical formula C8H10N4O2 and the chemical name 1,3,7-trimethylxanthine. It is found in around 60 different plants, with the chemical name 1,3,7-trimethylxanthine being the most common. Every day in the United States, over 450,000 cups of coffee are drank. The majority of people obtain their caffeine from either coffee beans or tea leaves, or from other drinks that contain caffeine that has been extracted, or from diverse natural sources like as cocoa beans, the kola nut, the Yaupon Holly, yerba mate, and guarana berries, among others.

Caffeine in Folgers Black Silk

Folgers Black Silk contains approximately the same amount of caffeine as normal Folgers coffee. As previously stated, only around 5% of the caffeine content of coffee is lost during the roasting process from a light roast to a dark roast. If you drink Folgers Black Silk coffee, you will not experience a significant reduction in caffeine. Folgers coffee contains 30-40mg caffeine per 1 tablespoon of ground coffee, which is 60-80mg caffeine per 12-ounce brewed coffee. If you drink Folgers coffee, you will not experience a significant reduction in caffeine.

How can I figure out how much caffeine is in my cup?

I looked over everyone’s responses and conducted some of my own research in order to come up with an estimation approach that I am satisfied with and that may be useful to others as well. My estimation is that it should be around 20% correct. Coffee that has been weakly extracted may give 0.6 percent of its weight in caffeine, whereas coffee that has been extremely strongly extracted may provide close to 1 percent caffeine. These percentages are for standard Arabica mixes that are 100 percent Arabica or largely Arabica.

The following is an explanation:

Maximum caffeine content

When tested using a spectrophotometer, typical premium roasted Arabica coffee beans such as mine have less than 1 percent caffeine by mass (p 311), but Robusta (which is less common and is commonly combined with Arabica in lesser coffees) contains almost twice that amount. As an upper limit, you should be allowed to utilize the following if you have a health issue such as wishing to keep within the 300 mg recommendation for pregnant women: Caffeine content per gram of Arabica coffee is around 100mg per gram of coffee.

One scoop of beans contains approximately 12 grams (yes I tared the scoop, but I did only weigh once and am not comparing light or dark roasts which will vary in weight and volume).

Ideally, that would serve as the upper limit of this estimating exercise. No more than 120mg of caffeine will be present in the strongest, largest, or weakest cup of coffee I can make with that scoop of beans.

How strong is my cup?

Typical American-style brewing processes and water ratios result in disolved coffee solids ranging from 1 percent (weak) to 1.65 percent (very strong), with 1.25 percent deemed ideal. Although the usual coffee has 1.8-2.2 percent solids, a regular espresso contains on average 1.8-2.2 percent solids. In other words, one cup of brewed coffee or espresso weighs almost the same as one cup of water (29.57 g) and contains between 1-2 percent coffee solids (so about 300-600mg, or 380mg solids for optimal brewed coffee and 600mg solids for espresso).

  1. On the other hand, caffeine is likely to be more soluble than the other components of the bean, thus even while it accounts for just 1% of the total mass of the beans, it accounts for significantly more than 1% of the total dissolved solids in the beans.
  2. According to, brewed coffee has 8-15 mg caffeine per ounce, whereas espresso contains 30-50 mg caffeine per ounce.
  3. The caffeine content of an ounce of “optimal” brewed coffee is 2.5-4.0 percent of the solids (380 mg) while the caffeine content of an ounce of espresso is 5.0-8.3 percent of the solids (600 mg).
  4. So, let’s suppose that the maximum 12 mg caffeine per ounce of coffee equates to 1.65 percent or 500 mg solids (1.65 percent of 29.57 gr = 500 mg) of the total caffeine.
  5. If I brew it “too weak” and it ends up with 1 percent solids (or 300 mg per oz), I’d assume I’d receive no more than 60 percent of the maximum caffeine, 7.2 mg (again 2.4 percent of the solids) per oz or 72 mg for a 10oz cup, according to my calculations.
  6. Given that I believe a nice cup of coffee falls somewhere in the center, I’ll estimate that my normal cup includes around 100 mg of caffeine from its 12g dry coffee, which is approximately 80 percent of the maximum caffeine content of the beans themselves.
  7. The caffeine content in American-style brewed coffee is around 0.8 percent (or 0.008) of the mass of the beans used, or 80 milligrams (mg) of caffeine for every 10 grams (g) of dry coffee.

Bonus corollary/sanity check

With the same method, an espresso shot made with 7g of ground coffee has a maximum caffeine content of around 70mg (77mg if the coffee is 10 percent Robusta, which is sometimes typical for Espresso blends), but because the serving size and strength of espresso shots are more standardized than those of brewed coffee, the 64mg/shotreported by the USDA and others actually represents 80-90 percent of the caffeine present in the beans.

How much caffeine is in a tablespoon of ground coffee?

“I’ve been curious about how much caffeine is in a tablespoon of ground coffee (the actual grounds), but I can’t seem to locate an answer on Google.” Please assist if you are able.” – John Y. Y. Y. Answer: John, you’ve asked an excellent question! I have a difficult time answering coffee-related questions without being very excited, so this will almost certainly be lengthier than the response you were expecting:). Let’s get this chemistry thing out of the way first. Caffeine and another alkaloid known as trigonelline make about one percent of the weight of green, unroasted coffee, which is a significant amount.

  1. As it roasts, green, unroasted coffee becomes more thick and heavy with moisture, which is ejected from the coffee bean as the bean becomes more fragrant.
  2. This is the point at which the discussion over whether or not various roasts of coffee contain varying quantities of caffeine gets underway.
  3. At the time, I wasn’t alone in thinking that a “strong coffee” was synonymous with being dark-roasted, as I recall many people thinking the same.
  4. But hold just a sec, there are a number of alternative perspectives on the situation!
  5. Making matters worse, assuming the preceding assertion is correct and coffee loses weight at a faster rate the darker it is roasted, we’re back to the misconception that a dark-roasted coffee loses weight at a faster rate while maintaining the same caffeine content.
  6. Please accept my apologies for the digression.
  7. This would imply that caffeine would decrease from 1 percent of the coffee’s composition to around 1.2 percent.
  8. 180 mg is 1.2 percent of 15 grams, or 1.2 percent of 15 grams.

In my research, I discovered that one metric cup of coffee has around 95 mg of caffeine, which is amusing because that quantity is precisely half of what I calculated previously.

How Much Caffeine Is Present In Coffee – Are You Consuming Too Much?

Your coffee habit dates back years, but have you ever pondered how much caffeine is actually in your cup of joe? What about a cup of espresso? It’s possible that you’re consuming too much. According to Patrick Maloney, Co-Founder of, about 151 million standard bags/sacks of coffee are used per year, with each bag containing 60 kg of coffee. In addition, just 20 grams of coffee are required to make an excellent cup of coffee. The equivalent of 151 million bags x 3,000 cups is 453,000,000,000 cups of coffee each year, with an average daily consumption of around 1,241,095,890 (1.24 Billion) cups.

Everyone who consumed espresso-based beverages in the United States last year was male.

Total consumption of coffee in the United States is estimated to be over 150 million cups per day, or more than 140 billion cups per year, making it the world’s top consumer of coffee.

Look at how much caffeine is consumed by coffee consumers and see what type of statistics or percentages we can come up with as a result.

Caffeine Intake

The caffeine content of a regular cup of coffee, which is generally an 8 oz. cup, is 95 mg. That is only one cup, mind you. Obviously, if you consume more alcohol than that, the figure will rise. If you add a shot of espresso to the mix, the temperature will almost certainly climb! With that much caffeine in your system, you could definitely cook an egg without moving. It is possible that some people do this on a daily basis in order to pull themselves out of bed in the mornings. Consider the information in the chart below.

Coffee drinks Size in oz. (mL) Caffeine (mg)
Brewed 8 (237) 96
Brewed, decaf 8 (237) 2
Espresso 1 (30) 64
Espresso, decaf 1 (30)
Instant 8 (237) 62
Instant, decaf 8 (237) 2

Following the chart, you may drink a “brewed” cup of coffee with a one-ounce shot of espresso and be good to go until the following week! That is a total of 160 mg of caffeine consumed in one session. You may go for the less caffeinated option, which would be instant coffee with 62 mg of caffeine, and then add your espresso shot for a total caffeine content of 126 mg. Obviously, there are other coffees available that have far more caffeine. Before ordering something that may be a little too much for you at one time, you may consult a list provided by the coffee shops.

In most cases, one cup (8 fl oz) of coffee has 95 mg of caffeine.

If you don’t want the extra energy boost that comes from caffeine, going the decaffeinated way is a good option.

But what’s the point of that? It’s also important to remember that those figures are based on an 8-ounce cup, not the massive mug that sits on your desk at work!

How much caffeine is considered safe?

Up to 400 milligrams of caffeine per day is permitted, which is deemed safe for the majority of individuals. Everyone, however, is unique, and your caffeine consumption will differ from that of others, as will their sensitivity to caffeine. Consider reducing the quantity of caffeine you consume during the day if you suffer from headaches, restlessness, or anxiety. Women who are pregnant, attempting to get pregnant, or who are breastfeeding are also encouraged to reduce their daily caffeine intake, if not to avoid it altogether.

Doctors recommend that such ladies consume 200 milligrams of caffeine per day, which is the recommended maximum amount.

It’s also important to remember that the actual quantity of caffeine in a cup of coffee (or tea) may (and will) vary significantly across individuals.

In order to assist you navigate through the caffeine consumption, utilize the figures on the chart as a reference.

What are the side effects of too much caffeine?

Anything that contains caffeine is almost certain to have some form of adverse effect. There are some people who have no difficulties at all with caffeine, and then there are others who have a few troubles with it when used in excess. The following are some of the possible adverse effects that a person may experience:

  • Many people have difficulty falling asleep
  • A sensation of irritability or anxiousness, or a feeling of being restless
  • A feeling of dizziness or shaking
  • If you consume too much, you may have heartburn and stomach discomfort. Having a racing feeling in your heart or an irregular heartbeat
  • Going to the restroom too frequently is a problem for some people. Excessive consumption will also elevate your blood pressure.

For someone who is unfamiliar with the effects of excessive coffee, especially if it is not something they do on a regular basis, it may be a frightening experience. The diuretic effect of caffeine (particularly in coffee and espresso) means that you can get dehydrated extremely rapidly and without warning if you consume it. I believe that everyone has suffered from some degree of dehydration at some time in their life, and it is a miserable state to be in.

My Thoughts

Caffeine is regarded to be a legal drug, and quitting it might be more difficult than quitting cigarettes. When you consume anything containing caffeine, pay attention to your body’s signals; it will not lie to you. Always keep it genuine, pay attention to the labels, and be mindful of the amount of caffeine you consume on a regular basis. For any issues you may have concerning caffeine, you should consult with your doctor before taking any action. It might be detrimental to your health if you consume too much of it.

WHERE TO BUYCoffee CalculatorMost Caffeinated CoffeesWHERE TO BUY The amount of caffeine present in a cup of coffee might vary depending on the brewing technique employed. This item refers to coffee prepared from Arabica coffee beans, which are a kind of coffee bean. See this page for information on coffee prepared from Robusta beans.

Any technique of preparing coffee in which hot water is allowed to come into contact with coffee grinds for an extended length of time is referred to as brewed coffee. In general, two teaspoons of ground coffee are used for every six fluid ounces of water while making brewed coffee.

Coffee Brewing Techniques

There are a variety of processes for brewing coffee, including concentrate brewing, Turkish or Greek brewing, vacuum brewing, percolating, or the French press (also known as press pot or plunger coffee), as well as drip or filter brewing and coffee extraction.

Brewed Coffee Quality

Arabica coffee beans can be of varying quality, and in general, the cheaper the price, the worse the quality of the bean will be in most cases. I recently went on a tour of theCafe Don Emiliocoffee plantation, which is located near the town of Uvita, Costa Rica. It was a pleasure to be guided through the entire coffee growing process by the producers, who demonstrated all of the hard work that goes into producing high-quality coffee beans that are harvested by hand and processed properly. Many low-priced coffee companies purchase low-quality beans or beans that have not been fermented, leaving the fruit covering the bean on the bean.

Try to choose high-quality coffee whenever possible for the best flavor and antioxidant content.

Coffee Caffeine by Brewing Methods

Caffeine levels in coffee drinks, like other beverages containing caffeine, can vary substantially depending on the coffee blend used, the amount of ground coffee used, and the brewing procedure employed.

Brewed Coffee Type Caffeine per 8 fl. oz.
Drip or Filter 115-175mg with an average of 145mg
French press or plunger 80-135mg with an average of 107.5mg
Percolated 64-272mg with an average of 200mg
Boiled (Turkish or Greek) 160-240mg with an average of 200mg

The amount of caffeine found in the brewed coffee displayed above is an average, with values ranging between 64 and 272 mg per cup on a typical day. Brew coffee has a greater caffeine content since it needs the water to be in touch with the coffee grounds for a longer period of time than other types of coffee (and sometimes an over-extracted taste).

Drip Coffee (Filter Coffee) is the Most Popular

Drip coffee, often known as filter coffee, is possibly the most common type of brewed coffee in the United States, at least. Coffee houses such as Starbucks, Dunkin Donuts, McCafe, and numerous more establishments follow a similar strategy. It is even true that K-cups are a form of drip brewed coffee.

What About Espresso Coffee?

The caffeine content of espresso coffee, contrary to popular belief, is not more than that of brewed coffee. During the preparation of espresso, the ground coffee comes into touch with the hot water for only a brief length of time (an “express” coffee). As a result, unlike brewed coffee, there is less caffeine released during the extraction process. Learn more about the caffeine content in espresso coffee.

Instant Coffee?

It is possible to make instant coffee by brewing the coffee (as part of the production process) and then dehydrating (typically by freeze-drying) the coffee to produce water-soluble granules. It is determined by the number of teaspoons of instant coffee granules you use in hot water to determine the quantity of caffeine in your beverage. For the majority of individuals, this price is far less than the cost of a cup of freshly made coffee. Learn more about caffeine in instant coffee, or compare the popularity and flavor of different instant coffee blends by clicking on the links below.

Iced Coffee

Iced coffee from well-known coffee shops can be created from either brewed or espresso-brewed coffee beans.

There is a common misconception that iced coffee has less caffeine than regular coffee; however, this is not true. In terms of caffeine content, they are on par with their hot counterparts. More information about caffeine in iced coffee may be found here.


Black coffee is often regarded as a calorie-free beverage. The milk and sugar are responsible for the majority of the calories.

Compared to Other Items

A cup of brewed coffee has 20.38 mg of caffeine, or 20.38 mg per fluid ounce (68.90 mg per 100 ml). A cup of coffee with 163 mg of caffeine has a total caffeine content of 8 fl oz.


In terms of caffeine intake, coffee is the most common food source. An average cup of coffee will provide you with around 95 mg of caffeine on average. However, the quantity of caffeine in different coffee drinks varies, and can vary anywhere from practically nothing to more than 500 mg per cup. This is a comprehensive guide on the caffeine level of various types and brands of coffee, including espresso.

What Factors Affect Caffeine Content?

The caffeine concentration in coffee is determined by a variety of factors, including:

  • Coffee bean types: There are many distinct varieties of coffee beans available, each of which may naturally have a varying quantity of caffeine. Roasting: Lighter roasts contain more caffeine than darker roasts, despite the fact that darker roasts offer a more complex flavor. Type of coffee: The caffeine level of various types of coffee, including conventional brewed coffee, espresso, instant coffee, and decaf coffee, can differ greatly. Serving size: The volume of “one cup of coffee” can range from 30–700 mL (1–24 oz), which has a significant impact on the overall caffeine level.

Bottom Line: The amount of caffeine in a cup of coffee is determined by the type of coffee bean used, the roast style used, how the coffee is made, and the serving size.

How Much Caffeine Is in a Cup of Coffee?

The sort of coffee you consume is the most important factor in determining its caffeine concentration.

Brewed Coffee

In the United States and Europe, brewing is the most frequent method of preparing coffee. The process of brewing coffee, sometimes referred to as ordinary coffee, involves pouring hot or boiling water over ground coffee beans, which are typically enclosed in a filter. One cup of freshly brewed coffee (8 oz) has around 70–140 mg of caffeine, or an average of 95 mg per cup ( 1 ,2).


Using a modest amount of hot water or steam, espresso is created by pressing the beans through a finely ground coffee grinder. Despite the fact that espresso has more caffeine per volume than normal coffee, it often contains less caffeine per serving due to the fact that espresso portions are typically tiny.

A single shot of espresso is typically 30–50 mL (1–1.75 oz) in volume and contains around 63 mg of caffeine ( 3 ). As a result, a double shot of espresso contains around 125 milligrams of caffeine.

Espresso-Based Drinks

Many popular coffee beverages are produced by combining espresso shots with a variety of milk kinds and quantities in various proportions. Lattes, cappuccinos, macchiatos, and Americanos are examples of such beverages. Because the milk does not include any extra caffeine, the caffeine content of these beverages is the same as that of a cup of plain espresso. A single (small) cup of coffee has around 63 mg of caffeine on average, whereas a double (large) cup contains approximately 125 mg.

Instant Coffee

Many popular coffee beverages are produced by combining espresso shots with a variety of milk kinds and quantities in different proportions. Lattes, cappuccinos, macchiatos, and Americanos are among the beverages available. As a result, because the milk does not contain any extra caffeine, the caffeine content of these beverages is the same as that of an espresso shot. Single (small) cups of coffee typically contain 63 mg of caffeine, whereas double (large) cups often have 125 mg.

Decaf Coffee

However, despite the fact that the name implies otherwise, decaf coffee does not contain zero caffeine. This beverage can include variable quantities of caffeine, with the average cup holding 3 mg. The caffeine content can range from 0–7 mg per cup, with the lowest cup containing 0 mg ( 5 , 6 , 7 ). However, depending on the kind of coffee, the technique of decaffeination used, and the size of the cup, some variations may have even greater levels of caffeine than others. The bottom line is this: The typical caffeine level of an 8-ounce cup of freshly brewed coffee is 95 milligrams (mg).

Are Commercial Brands More Caffeinated?

The caffeine content of some commercial coffee brands may be higher than that of conventional, home-brewed coffee. Coffee shops are especially well-known for serving huge cups of coffee, which may be as much as 700 mL in size (24 oz). The amount of coffee included in such cups is approximately the same as 3–5 regular-sized cups of espresso.


Starbucks is, without a doubt, the most well-known coffee establishment in the entire globe. It also serves some of the most highly caffeinated coffee available on the market. The caffeine concentration of brewed coffee at Starbucks is as follows (8,9): caffeine content:

  • 180 mg for a short (8 oz)
  • 260 mg for a tall (12 oz)
  • 315 mg for a grande (16 oz)
  • 415 mg for a venti (20 oz).

In addition, one shot of espresso at Starbucks has 75 milligrams of caffeine, which is considered moderate. As a result, all small espresso-based beverages include 75 milligrams of caffeine per serving. This comprises beverages such as lattes, cappuccinos, macchiatos, and Americanos, among other things (10). Larger versions (16 oz), which are created with two or three espresso shots (16 oz), also include 150 or 225 mg of caffeine, depending on the size. Starbucks decaf coffee has 15–30 mg of caffeine per cup, depending on the size of the cup.

The bottom line is that an 8-ounce cup of Starbucks brewed coffee has 180 milligrams of caffeine. The caffeine content of a single espresso and espresso-based beverages is 75 mg, but an 8-ounce cup of decaf coffee contains around 15 mg of caffeine.


Almost everywhere in the globe, McDonald’s offers coffee under the McCafe brand; the company also sells tea. Even though they are a major fast food corporation that sells coffee, they do not standardize or quantify the amount of caffeine in their beverages. According to our calculations, the caffeine concentration of their brewed coffee is around (11):

  • A small (12 oz) serving has 109 mg of sodium
  • A medium (16 oz) serving has 145 mg of sodium
  • A large (21–24 oz) serving has 180 mg of sodium.

Its espresso includes 71 mg of caffeine per serving, while its decaf contains 8–14 mg, depending on how big a cup you have. The bottom line is that McDonald’s does not standardize the amount of caffeine contained in their coffee beverages. According to our calculations, a small cup of freshly brewed coffee has 109 mg of caffeine. Espresso has around 71 mg of caffeine, whereas decaf includes approximately 8 mg.

Dunkin Donuts

Dunkin Donuts is another another coffee and doughnut store business that is extremely popular all over the world. It has the following amount of caffeine (12) in their freshly brewed coffee:

  • 215 mg for small (10 oz)
  • 302 mg for medium (16 oz)
  • 431 mg for large (20 oz)
  • And 517 mg for extra large (24 oz).

One of their espresso shots has 75 mg of caffeine, which is also the amount of caffeine you can anticipate to get from one of their espresso-based beverages. The decaf coffee served at Dunkin Donuts may also contain a significant amount of caffeine. According to one source, a small cup (10 oz) of coffee has 53 mg of caffeine, while a large cup (24 oz) contains 128 mg of caffeine (13). That’s nearly as much caffeine as you’ll get in most other types of normal coffee, if not more. A small cup of Dunkin Donuts coffee has 215 mg of caffeine, whereas a single espresso contains 75 mg.

Is Caffeine Something to Worry About?

Coffee is abundant in antioxidants, and several studies have shown that coffee is beneficial to one’s health. Getting too much coffee, on the other hand, has been related to negative side effects such as anxiety, sleep interruptions, heart palpitations, and restlessness ( 14 , 15 ). Caffeine consumption of 400–600 mg/day is typically not related with any negative effects in the majority of persons. This equates to around 6 mg per kilogram (3 mg per pound) of body weight, or 4–6 typical cups of coffee per day ( 16 ).

Some people are extremely sensitive to it, while others are completely unaffected by enormous doses of it.

It’s simply a matter of trial and error to determine the appropriate amount.
