Sorry guys. but...

Weed is classified as a hallucinogen.

However, it does NOT make you hallucinate and hallucinogens are not actually called that because they make you hallucinate, but because of the way they affect your mind 'n shit.

One thing that most of these drugs do not do, despite the ingrained usage of the term hallucinogen, is to cause hallucinations. Hallucinations, strictly speaking, are perceptions that have no basis in reality, but that appear entirely realistic. A typical "hallucination" induced by a psychedelic drug is more accurately described as a modification of regular perception, and the subject is usually quite aware of the illusory and personal nature of their perceptions. Some less common drugs, such as DMT and atropine, may cause hallucinations in the proper sense.
