I'm almost 40 and have smoked weed since I was 13/14 years old. Dabbled in other drugs as well, but never developed an addiction to them. I could simply do a line or 5 a night and not touch coke again for years. Same with alcohol.
Since I have been smoking weed for most of my life, I guess that qualifies as a proper addiction. Especially because I could never regulate my consumption, e.g. only smoke on the weekends. It was a daily thing for me during many years. Thankfully, I was never the wake and bake type. Instead, I'm rather high functioning person: Good job in STEM, active in sports and have a decent amount of friends.
Close to a month ago, I decided to quit. I'm not sure why, but I just did. Cold turkey. I still have an ounce or so at home but I have no intention of touching it, nor have I come close to relapsing yet. I used to think of weed as pretty harmless and for sure it's not meth. That said, I realized that after 2-3 weeks of abstinence, a bunch of bottled up emotions came up. Got sad over things which happened in the past and I mean proper sad. Tears and all. Pretty weird feeling for me, as I'm not a super emotional man by any means. This is still going on and is pretty interesting. I function just fine, hang out with friends, work, hit the gym, etc. but then I get these gloomy/sad feelings. I just observe them and let them run out. Let's see how long this lasts.
Anyway, what I'm trying to say is that, at least for me, weed was indeed some kind of coping mechanism to numb unpleasant emotions. Pretty stereotypical and pretty unhealthy. It only took me 26 years to figure it out.
I have to admit that writing this is a bit embarrassing. Morale of the story, be smarter than me kids. Just say no.
Take the next step: throw that ounce away unceremoniously.
If you're over it, if it has no control over you: your mind won't even think of the word 'waste'.
I once did so with half a handle of whiskey in a conversation about addiction with a friend.
Did it a bunch more times with other stuff whenever I found myself... Enjoying myself too easily.
