5 Classes of Drugs Flashcards

A drug is a substance that alters body functions and is distinct from food.
Stimulants increase central nervous system (CNS) activity, potentially enhancing alertness and energy.
Depressants decrease CNS activity, often inducing relaxation and reduced anxiety.
Hallucinogens affect perception, altering sensory experiences and perceptions of reality.
Narcotics provide calming and sedative effects, often used for pain relief.
Inhalants are substances inhaled to produce psychoactive effects, typically delivering a quick high.

Synthetic drugs are artificially created in laboratories, having no natural counterpart.
Semi-synthetic drugs start with natural substances but are chemically altered by humans to modify their effects.
Natural drugs occur naturally in the environment and are often derived from plants or organic sources.

Addiction refers to an uncontrollable dependence on a drug, leading to compulsive behavior.
Tolerance is the phenomenon where increasing doses of a drug are needed to achieve the same effect due to physiological adaptation.
The Reward Pathway involves the brain's release of neurotransmitters like dopamine, serotonin, and melatonin, triggered by drugs, leading to feelings of euphoria or a "high."

Depressants include PCP, Ketamine, Heroin, Alcohol, and Ecstasy, often associated with relaxation and pain relief.
Stimulants consist of Cocaine, Ecstasy, and Methamphetamine, linked to heightened energy and alertness.
Narcotics examples are Heroin, PCP, and Ketamine, primarily used for pain management.
Hallucinogens include LSD, Psilocybin, Peyote, and Mescaline, known for altering perception and cognitive processes.
Inhalants such as Nitrous oxide, gasoline, and Sharpie are primarily used for their fast-acting effects.
