I remember when a recovered alcoholic came to our school to talk to us about alcoholism.
One of my class mates asked "when did you realise you were addicted?", he answered "when I'd wake up to swig some vodka and then just go back to sleep again".
So yh, you might be right. I personally don't think cannabis is as destructive as many other well known drugs, but it can still be a bad habit and you can always have too much of a good thing.
Makes me think of how we perceive the flow of time; how novel experiences create a flood of memories, potentially affecting your perception of the flow of time to make your life feel like it has lasted longer. And then I think about those old friends, with an extremely limited amount of novel experiences after high school... We used to jam all the time, they all played an instrument of some kind and they've all long given up in favor of endless wake and bake and being perpetually high. It doesn't ruin your health quickly like other drugs, it just has a tendency to convince people its OK to do literally nothing. There's a time and place for that; many times and many places, actually. Its when that time and place becomes all the time and everywhere that it can be insidious.
I bet the last thing anyone ever thinks on their death bed is "I really wish I smoked more weed".
On the other hand, a person with an addict's brain is going to almost certainly spend their youth, their 20s and a good chunk of their 30s as addicts before they start their path toward sobriety.
As somebody with an addict's brain who got hooked on weed instead of anything else, I am thankful it was weed and I wish all people with my chemical imbalance could have had weed as their poison.
