>In that sense if you're allowing whether or not a drug is recreational to depend on a person's makeup, how could you have known I was taking a recreational dose? that is literally the point of a psychiatrist. there is only the law preventing psychiatrists from administering psychedelics like LSD in the same fashion. there are natural practitioners who do this for e.g. marijuana today. if someone has an adverse reaction (bad trip) then the doctor usually alters the administration of the medicine in some manner (Lower dosage, increase dosage, change medication all together etc). but to say that there are only recreational doses for illicit drugs and there is no method to validate potency in human consumption is disingenuous. a drug is a chemical. our body is nothing but a chain of chemical reactions. modern medicine and science has come up with a pretty good method of determining dosage
