I was planning on attending a 4 day outdoor rave in a week, and was also planning on consuming multiple substances while he attended. I was unsure whether the combination of vitamins and psychoactives could pose possible health threats and contradict each other negatively. In example, taking MAOI's with certain substances, too high of a heart rate with combined substances, etc. The substances that I was planning on consuming included MDMA, ketamine, cannabis, nitrous oxide, salvia, a few beers, some benzos to help come down, and then some ginko biloba, 5-HTP, and Co-enzyme Q10 for vitamins. Of course I am not planning on consuming all these substances at once, but over the course of the 4 days. Also, are there any substances that I should not consume if he is planning on taking the stated substances? Or possibly some vitamins that I should consume? Any information is greatly appreciated.
