I would stay in school, I would sit down and have a chat with your parents and REALLY look at your options about quiting the other problem you have, FULL time job.. Do what you can, borrow money, get a grant for this or that. Stay in school and do what is best for you. Remember the brain is just a muscle and you always have to be working it.
school and weed isn't hard. Just have to enjoy and not to indulge.


good luck with the decision.
