subject of meditation as a start is clearing subconcious from recordings.psychotropic drugs are grounding the analytical part of the brain and leave the reactive open so you're coming to a state of induction.after that the reactive part is leaving the subconcious open to constant non controlled recordings and fills it with useless information which then overloads and start vomiting hallusinations.And personally i think that if you wanna use drugs its fine but there is no potential for meditation with psychotropic.
