Will this way of living harm me one day?

I'm 17 years old. I have been a regular marijuana user for over 2 years and took Lsd once. My problem is that I can't stay sober for long. I'm leaving aside the issues of mental health and developing the habit of not being sober. Will I have serious consequences such as brain damage and difficulties in adult life if I continue living this way? (I have never taken or plan to take hard drugs) (I smoke on average once every 2 weeks) (I plan to take some mushrooms to think deeply about my problem, is this a good solution?)
