It is most commonly consumed by humans in infusions extracted from the seed of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut.

What is Caffeine used for?

Effects of Caffeine Powder.


  • Stimulation – Caffeine is reported to be mildly to moderately energetic and stimulating in a fashion that is considerably weaker in comparison to that of traditional recreational stimulants such as amphetamine, MDMA or cocaine. This encourages physical activities such as performing chores and repetitive tasks which would otherwise be boring and strenuous physical activities. The particular style of stimulation which caffeine presents can be described as forced. This means that at higher dosages, it becomes difficult or impossible to keep still as jaw clenching, involuntarily bodily shakes and vibrations become present, resulting in extreme shaking of the entire body, unsteadiness of the hands, and a general lack of motor control.
  • Appetite suppression
  • Bronchodilation – Caffeine is an effective bronchodilator. In clinical tests on adults with asthma, at fairly low doses (5mg/kg of body weight), caffeine has been shown to provide a small improvement in lung function.
  • Dizziness – This effect is not common except at overly high doses or taken when fatigued or at low blood sugar.
  • Frequent urination – When doses of caffeine equivalent to 2–3 cups of coffee are administered to people who have not consumed caffeine during prior days, they produce a mild increase in urinary output. Most people who consume caffeine, however, ingest it daily. Regular users of caffeine have been shown to develop a strong tolerance to the diuretic effect.
  • Headaches and Headache suppression – Caffeine can suppress headaches at light and common dosages, but may cause headaches at higher ones. This is likely due to its vasoconstricting and a vasodilating effects.

Lethal dosage

Extreme overdose can result in death. The median lethal dose (LD50) given orally is 192 milligrams per kilogram in rats. The LD50 of caffeine in humans is dependent on individual sensitivity, but is estimated to be about 150 to 200 milligrams per kilogram of body mass or roughly 80 to 100 cups of coffee for an average adult. Though achieving lethal dose of caffeine would be difficult with regular coffee, it is easier to reach high doses with caffeine pills, and the lethal dose can be lower in individuals whose ability to metabolize caffeine is impaired.

It is strongly recommended that one use harm reduction practices when using this substance.

Legal Status

Caffeine is legal in nearly all parts of the world. However, it is often regulated because it is a psychoactive substance. For example, in the United States, the Food and Drug Administration (FDA) restricts beverages to contain less than 0.02% caffeine. unless they are listed as a dietary supplement.
