Stimulants such as amphetamines, nicotine, ecstasy, and cocaine lead to increased activity of the CNS. Cocaine leads to prolonged effects of dopamine, which is a transmitter. Nicotine withdrawals result in anxiety, moodiness, and irritability.

Opioids like heroin and morphine cause the dullness of the senses, relieve pain, and cause sleep. They activate the receptors that are plenty in the brain.

Hallucinogens like the LSDs and PSPs distort the perception making the user hallucinate and be delusional. Cannabis affects the dopamine release that is involved in learning.
