Which two types of stimulants are most commonly recognized?

The most commonly recognized types of stimulants are amphetamines and cocaine. Stimulants are substances that increase activity in the central nervous system, leading to heightened alertness, attention, and energy. Amphetamines are synthetic drugs often prescribed for conditions like ADHD but can be misused for their stimulating effects. Cocaine, derived from the coca plant, is a powerful stimulant that creates intense euphoria and increased energy but also comes with a high risk of addiction and adverse health effects.

Understanding the classifications of drugs is crucial, as it informs law enforcement and health professionals about the potential risks and legal implications associated with misuse. Other options mention depressants or opioids, which are not stimulants and therefore do not fit the criteria for being recognized as such.
