“Stimulants are drugs that directly affect the central nervous system. They work to speed up parts of the brain and body, increasing the heart rate, blood pressure, metabolism and body temperature of the user. They are used by athletes to reduce tiredness and fatigue, and to increase alertness, competitiveness and aggressiveness.
The most common stimulants detected in anti-doping tests include amphetamines, cocaine, ecstasy and methylphenidate (Ritalin). The actual effects vary according to the drug and its method of ingestion—drugs that are snorted or injected will produce more immediate results than those that are taken in pill form.
Nicotine and caffeine are also frequently used as stimulants but they are not banned in sports. However, both substances are currently on the WADA Monitoring Program for 2018. WADA is observing them in order to detect potential patterns of misuse in sport.”Apr. 19, 2021
