Ya it was disrespectful do blow smoke in your mom's face but her calling you addicted and threatening to put you through rehab is pretty shitty. I know you should respect your mother but if mine came out and said something like that I would be pissed too. Whenever someone comes here with a story involving their parents there are people who say that you should respect their rules or get out, but really I think you might be hypocrits if you smoked when you were kids and your parents wouldn't agree with it. And lastly from when whoever made the thread said they smoke before bed, maybe that helps him get to sleep at night which is actually a more positive way to use marijuana rather than the countless others just use it to get high.
