Recreational drugs encompass a diverse range of psychoactive substances used for pleasure or social experiences, categorized primarily as depressants (like alcohol, cannabis, and opioids), stimulants (such as cocaine, amphetamines, and nicotine), and hallucinogens (including LSD and psilocybin). Their use can induce short-term effects like altered mood and perception, and long-term consequences such as addiction, mental and physical health problems, and social issues. The risks associated with recreational drug use are significant, including overdose, addiction, mental health complications, physical damage, risky behaviors, legal troubles, and the dangers of impure substances and drug interactions, highlighting the importance of understanding these potential harms.
