I don't wish to discuss that necessarily. But I feel that any discussion of substances that have been illegal, or still are illegal in some places, or which have not been subjected to clinical trials, should be at least a little bit vulnerable to that small voice which says that you need to be cautious and not expect miracles. Marijuana has addled many a brain and stunted many a personality on this planet. Plenty of negatives really. Good luck to you if you indulge, but beware of enthusiastic advocacy from biased fellow users. That's all.
