What hallucinogen is known to have withdrawal symptoms?

Marijuana is recognized to have withdrawal symptoms, which distinguishes it from other substances commonly associated with hallucinogenic effects. While psychedelic mushrooms, LSD, and PCP are hallucinogens, they do not typically produce significant withdrawal symptoms when individuals cease use.

Marijuana can lead to a range of withdrawal symptoms due to its regular consumption impacting the brain's neurochemistry. Individuals might experience irritability, anxiety, changes in appetite, and sleep disturbances when they stop using marijuana after prolonged use. This makes marijuana unique among many hallucinogens, which is often characterized by the absence of withdrawal symptoms, thus supporting the identification of marijuana in the context of this question.
