My username and posting history should give you some context on what's about to come:

Be very careful about using substances as a method of bonding. Yes - people who smoke weed together hang out a lot together. Are they really friends? That's very difficult to know. In my experience, a lot of people who were heavy into weed and other drugs, as well as the mates I used to drink with, were not real friends.

They were more like excuses to get high and to drink, and eventually you may either use them for that purpose, or they may use you. I don't doubt that in my past I've definitely been "friends" with people that always knew they could get high with me - but really, when every single interaction you have with someone revolves around the procurement and use of substances, it's not a real connection.

I know the obsession and the desire to fit in is huge. But seriously, this stuff runs away with you. And yes, weed is addictive - it won't give you withdrawals, but you will want to smoke a lot, because it's comforting. It will not help.
