Combine, I was in your position a while back. I have stopped smoking cannabis and my life has been incredibly good since then. I made a thread a while back, you might find it, but some idiots decided to ruin it by insulting me and my decision to quit. I don't know if it got deleted because of those kidiots.

It sounds as if you aren't getting high because you smoke too often. Don't smoke every day. Make it a once a week or twice a month type thing. The high will be better.

There are many things to get your mind off cannabis. Play sports, pick up a hobby of your choice, listen to music, read books. I would suggest studying. If you are having difficulty concentrating, studying what you did in school that day will train your mind to pick things up faster in your daily life and in class (remember: learning is understanding and not memorizing) and will get you better grades (there is nothing wrong with trying to get the best marks as possible).

I hope I helped out.

Good luck.
