Dictionary

Uppers, or ups, is a slang term for a class of central nervous system (CNS) stimulant drugs that increase alertness, energy, and wakefulness. These drugs increase the release of neurotransmitters such as dopamine and norepinephrine, which are associated with increased mental and physical activity. Examples of uppers include cocaine, amphetamines (such as Adderall and methamphetamine), and prescription stimulants used for attention deficit hyperactivity disorder (ADHD).

The term uppers are often used to describe the effects of these drugs, which can include increased heart rate, heightened mood, and improved concentration and focus. However, uppers can also have adverse side effects, such as increased anxiety, paranoia, and insomnia. Additionally, long-term use of uppers can lead to tolerance, dependence, and addiction. The non-medical use of uppers is illegal in many countries, including the United States.
