Really the use of other psychoactives, even for spiritual reasons, is a subject far better suited to a forum set up for that topic, such as Erowid. The thread you describe, if I know anything about forums lol, would inevitably end up needing deletions and explanations and be a nightmare. If you think you can present it to stay focused on the general topic of cannabis and not stray off into the shark-infested waters of 'other psychotropics', cool... I think keeping it no moe specific than the catch-all would not be a problem; the problem will arise in trying not to discuss any specifics- Please use your very best judgement, and thanks for checking in first!
