not much you can do dude from the sound of your mothers reaction she has been severly brainwashed by the media and govt about the effects of cannibis i would do what you can to gain her trust back and get your shit together so you can move out on your own this is something that she obviously feels very strong about and prob wont change her mind but it is also not worth losing your family over so get your own place and just try to put it all behind you ..you can always find another dealer but you only have one set of parents and remember they act this way because they love and worry about you and in there propaganda addled brains they believe it is whats best for you. good luck
