I've smoked a joint while at an inpatient facility in Florida. My dude left AMA from the treatment center, went out and got wrecked on Xanax bars, IV oxycodone, ecstasy rolls, and cannabis. He had some weed left over and was able to conceal it while getting re-admitted into the rehab. He came up to me after a mandatory 12-step meeting we had to go to and was like "Yo you tryna smoke this loud with me tonight when we get back to the residence." Of course, I was all about it (I was not in treatment at that time by my own will. I was giving an ultimatum by family). I remember getting stupid high and then feeling mad paranoid when the staff came by to do a head-count. Luckily, I called myself out on it before I got drug-tested (which we all did 2-3x a week) and they let me stay.
Not long after that, dude that had come from a sketchy halfway house in Del Ray brought some liquid vape juice that was AB-FUBINACA in place of nicotine haha. I was basically tripping after taking several rips off the vape. It got 4 of us high as fuck. Me and one of my roommates proceeded to devour the food, which pissed off our other roommates.
I ended up drinking all the time months later, which I always got away with until one my roommates joined in and got fucking annihilated off of next to nothing and passed out in the bathroom with the shower running. I left before they could give me the boot. I ended up living at a house that one of my buddies who had relapsed in the halfway I was just at rented with some of his friends. It was a gaint, relapse shit-show. We were all shooting Dilaudid out the ass and they were soooo fucking expensive, it was unreal to maintain any proper habit down there and the dope I had from Miami was straight garbage. A dude I lived with was a previous employee of the rehab I graduated from, he had just recently quit and was in back in action (ahem... strung the fuck out). He still had a key and the code to the detox meds safe. I was the lookout while he went in there and stole mad amounts of valium, buprenorphine, clonazepam, clonidine, and seroquel. He gave me most the valium

luh dat shit
