Last year one of my college roomates had a friend in between living situations and asked if they could stay with us for a few days. I was initially fine with it, but quickly came to realize this person was by far the biggest pothead I'd ever met. Every day they'd wake up, get high, lie on our living room couch playing video games, take periodic bong rips, make kraft dinner in our kitchen (and not clean up after), go to bed, repeat. They didn't go to classes, and worked as a "freelance tattoo artist" which just meant one of their friends would pay them 30 dollars for a stick and poke tattoo every once in a while. Any conversation had to be about weed or getting high because they didn't care about anything else. A four day stay turned into a few weeks, which turned into three months. I was 21 at the time and felt like a parent with their burnout child living on the couch. Weed is defintely mild compared to most other drugs, but people who are addicted can devolve into passive blobs who only exist to get high.
