Hi Carson,
I appreciate your struggle. I believe you are in the right track though. We all have our struggles, but for me, as long as I keep meditating, I seem to be more "protected" and "aligned" than if not so I have faith that everything is going to be ok if I keep on having courage, faith and keep being aware of my insides.
Regarding Marijuana, I used it for a little while and I wouldnn't enjoy it for the long term. I can understand it can cloud the mind, so, for your own well being, I'd say it is better to be able to quit. I had great experiences but also some very bad ones. In short, I was not in control, it was clouding my mind. For me, that was a bad thing. But I do understand its appeal and only you can tell if you find it somehow beneficial or a hindrance.
