Traplord69 LOL, been there. I used to stay up for days shooting coke and then go to my weekly methadone pickups with blood all over my shirt, my arms, etc. And use someone else's clean+methadone piss that sat in the hot car every day for a month until it was cloudy and practically brown, so I could keep doing it.
But probably the most inappropriate time I was high was in undergrad, in a meeting with one of my teachers that was supposed to be about my final project which was about my drug use. He hated my attitude and how I wasn't ashamed or desperate to get clean and how that was what the work was about, he was lecturing me about all that under the guise of trying to improve my work...and I straight up nodded off right in the middle of our conversation. Pretty surprising considering how pissed off at him I was, but it was like one minute I'm fuming the next my eyes are closing.
He totally clocked me doing it, and was super condescending about it, as if I proved his point or something about what a fuck up I was. I wasn't even using heroin at that point, I was on the klinik, but I didn't want to give him the satisfaction of thinking I was trying to quit.
