Las drogas y el cerebro

Psychoactive drugs alter emotions, behavior, or consciousness by affecting neurotransmitters. They are categorized into stimulants, depressants, and hallucinogens. Stimulants like caffeine and cocaine increase alertness but can lead to a crash. Depressants such as alcohol and heroin slow brain activity and can cause withdrawal symptoms. Hallucinogens like LSD distort reality and may trigger mental illness. These drugs can be addictive and harmful to mental health.
