i wouldent quit because of what has happened
i would call it a minor setback ,shit like this happens to the best of us !!!!
when you fall a few times you learn to pick yourself up and get on with life the best way that you can
and i know smoking weed helps you get on with it
sorry about what has happened to ya and i hope you get the courage to try growing again ,as that good old saying goes

WE ALL LEARN FROM OUR MISTAKES
cheers all
