While fun in the beginning, cannabis can really propel you into a deep cycle of self-isolation. I know people who are 26 but have not developed much since leaving highschool because they've used cannabis as a crutch. I used to be friends with these people, attending the smoke-ups every weekend. Instead of going out and meeting people, learning, failing, and growing, these guys (myself included) just continued to smoke up. This group of guys, save one, all are either virgins or had their last girlfriend/fling years ago. It's a never ending cycle of being lonely/depressed -> meet up with the stoners to smoke to escape the pain. After awhile I started asking myself "Is this all there is?" and got out. I still meet up with them every few months to check in, but it's largely unchanged since the last time I saw them. The conversations are the exact same as they were. Any discussion had simply rehashes old ones that have been repeated countless times. There is simply nothing stimulating or progressive about groups like that. Learn to recognize go nowhere individuals/groups and steer clear. You may feel like part of a family inside these groups but you shouldn't sacrifice your own potential and future just to fit in. Most drug user groups aren't even really friends anyways, they just want a group of people to do drugs with. Take away the drugs, and there's little else remaining.
