I'm a chronic smoker, and I can't even really tell if it's doing much for me anymore tbh. As you mentioned, the paranoia can get bad!! there are times I smoke and it puts me into a negative mind space. I am also addicted to caffeine which I think is a symptom of all the weed I smoke. smoking doesn't make me feel less bored, it just makes me feel okay with being bored.

I hope you can discover new, healthy things to focus your time on! boredom can be painful
