If I was just using drugs to get fucked up I would agree with you that it is that simple. However I think trying to change someone after you started dating them is wrong especially when you knew what they were like before you started dating them. Let's say you where an avid marathon runner and ran all the time. Then you met someone special and started dating and they decided they hated running and wanted you stop. Would you stop for them? Obviously not because you don't see any downsides to your hobby and you see your partner as being irrational for wanting you to stop. I feel the same way about my drug use. I would say use of psychedelics has helped me mentally just as much if not more than exercise has helped me physically. And i know mdma does slightly damage your serotonin receptors with each use but I take it once every 3 months while supplementing with lots of nootropics to minimize the damage and I am a very happy and healthy person overall. Also I think the lessons it has taught me by far out way the miniscule amount of unnoticeable damage it has ever done to me. Either way, you should not be concerned with what I choose to put in my body. And I don't really care how non drug users view my use as a lot of them are misinformed and are too quick to pass judgement and I am comfortable with the decisions I make. I'd be willing to bet if you met me in real life you would have no idea that I use drugs unless I straight up told you and even then you might not believe me. I get great grades, have very healthy relationships (for the most part) and I work out 5 days a week. But I have made the decision to cut it off with her because I just can't see this working out long term
