Cannabis is considered, by some, to cause a person to hallucinate. I'm a long term, fairly heavy cannabis smoker but I have never hallucinated on cannabis; the plant material, hashish or any other cannabis extracts. Have you ever hallucinated, saw things that were not there, on cannabis alone, without the influence of other drugs? After much reading on the subject of cannabis, this question just kinda popped into my head. Thanks for your replies!
