Drug use can have a severe physical and mental impact on an individual. People should avoid any drugs that affect the immune system, blood pressure and/or impair the mental abilities of the individual. That said, many cultures have traditionally combined suspension with psychedelic, psychotropic, and “mind expanding” drugs to further their spiritual quests. However, as far as we in the West are concerned, this is highly uncharted territory and extreme care should be taken if you choose to combine these activities.
