Is marijuana an antidepressant or a depressant?

Marijuana produces varying effects in different patients, so it may be classified as a depressant, stimulant, or hallucinogen. As a depressant, marijuana may slow brain function, ease anxiety, relax muscles, bring about short-term memory loss, and cause dizziness and sleepiness. As a stimulant, marijuana may cause paranoia, anxiety, mood elevation, and tachycardia. As a hallucinogen, marijuana may bring about hallucinations, nausea, a loss of coordination, an altered sense of time or space, dry mouth,  tachycardia, and a detachment from oneself or one’s environment.
