Let's take an honest look at the places where we would find evidence or authority for it's use, and then make a determination.
1) Biblical evidence: There is nothing in the Bible, Tora or other Jewish/Christian texts that supports, either through direct command, example or necessary inference, that Marijuana, Mushrooms or any other plant or herb was used for purposes of hallucinating, getting high, etc.
2) Archeological evidence: There is no physical evidence or scientific research done to support the claim that the people in this area used Marijuana, Mushrooms or any other plant or herb for the purpose of hallucinating, getting high, etc.
The logical conclusion therefore, since there is literally no evidence to suggest otherwise, is that these people did not use these plants and herbs for that purpose, or even that they used them at all.
*On a similar note however, I think that Puff the Magic Dragon is living in northern New Jersey and is addicted to heroin. I have no proof of it, but I did read it on the internet, so it must be true.
