While I believe all drugs would be safer if they were legalized and regulated, I think your criteria for what constitutes a drug are arbitrary. MDMA has the potential to heal trauma, but it also has the potential to make people do or say things they regret later. Likewise, meth and heroin have a high potential for personal harm, but some people are able to use them safely for long periods of time. I don’t think it’s useful to debate what is and isn’t a drug.
