While I certainly don't do drugs like I used to, but when I was doing them, I was all in. I pushed the envelope with most drugs I did, with the exception of alcohol which I don't particularly have an affinity for at all. I have always worked hard, treated people well, have had and continue to have many relationships that I value. I always took a certain amount of pride in the fact that no one could tell (for the most part) that I was using drugs. I have worked corporate for many years, have been in ultra professional environments for decades, and currently own my business. And I will say that I don't fall into the category of stereotypical "drug user", as it were, for sure.
I remember once, as a younger dude, that I was tripping very hard at a friend's house and we were down in the living room when my friend's Mom and Dad joined us and started to chat, something that we often did, as we all got along famously. I recall my friend's Mom saying to me, "You're such an All-American boy", and I was just struggling to contain myself because I was literally tripping my brains out. I felt guilty for a moment, but of course I got over it shortly thereafter...LOL
I do know that being careful about not sharing certain details with people is a wise move. As an example, if I told some people I know that I've owned and consumed hundreds (many) of hits of LSD, that it would change the way they perceive me because of their own biases. In the absence of them knowing, they aren't allowed to do anything other than judge me for who I am, not who they think I might based on their own biases.
Everyone is on a "need to know basis", and I'll decide what people know...
