If you are looking for a legal substance that could also be smoked and chewed just like your regular marijuana, then I would suggest Salvia divinorum. I have been purchasing this plant from online retailers for years now since a friend introduced it to me. Yes, the hallucinatory effects really are uncontrollable at times but with moderation, you could use the Salvia divinorum just fine. One more thing is that Salvia divinorum has no reported side effects. Most users say that the effects of Salvia divinorum which includes hallucinations and uncontrollable laughter lasts for only a short period of time.
