You think that because you have a high tolerance to things like opiates and benzos that its going to be the same with ayahuasca/DMT. I had addiction issues in the past so i know why you think this way. Your not going to be immune to every medication on the planet so get that out of your head right now. DMT is the most powerful psychedelic known to man and it can make you mad. Start off small then work your way up. Please don't make the same mistake as me.
