In university I knew a girl named Noreen. I was roommates with our younger sibling at that point. I worked plus she went to university. Noreen was our sibling’s best friend, plus spent almost every evening at our apartment. My sibling plus I were both big-time pot smokers. Not just every single evening, but multiple grams worth every single evening! Every one of us hosted some epic parties, plus spent multiple fifths a day passing a joint back plus forth. Noreen consistently smoked cannabis with us, until a single evening something absurd happened plus she had to stop. Along with cannabis, all of us also dabbled with pills, mescaline, ecstasy, peyote, plus LSD. Noreen did a pressing dose of LSD a single evening plus it must have seriously affected her brain chemistry, because after that she could never smoke cannabis again. Something about the THC in cannabis would trigger the chemicals in her brain, plus make her recognize she was tripping on LSD again. This made cannabis something intense plus frightening instead of being a calming influence. Noreen couldn’t even be in the same room with us when all of us smoked cannabis, because the fifthhand smoke would make her all twitchy plus weird. Noreen was still a cool person after that, but because I was smoking so much cannabis she stopped hanging around really often. I l gained a lesson myself, because I never knew that LSD could change the way your brain responds to cannabis, however just to be on the safe side I never took acid again, because I appreciate smoking cannabis too much to ever lose it!
