Welcome Michael
I was a musician as well and a pot smoker for 30 years - I've been known to be seen crawling on my hands and knees to find the last crumbs of my stash in the carpet, or combing the streets around my house for the baggie I lost, so I get it a little.
It was definitely addictive and destructive for me and my friends.
I was terrified of reality. But I really wanted to change. That guy ^ was not who I wanted to be.
I just up and quit one day. I was sick and tired of it all. I was moving towns and I ran with the chance (unfortunately I took up drinking in earnest but thats another long sad story)
Sounds like it you could use a little support to do it smarter than I did.
You'll find a lot of support here - there are also things like Marijuana Anonymous in Canada - if there's not a meeting by you, an NA (Narcotics Anon) meeting could do too?
