Sounds to me like someone needs to go talk to doctor. I don't believe for a second that your dad calls you all these names, turns around and cares enough for you to stop smoking weed. If he didn't love you, he wouldn't care, but it shows that both your parents care for your own well being to keep you out of trouble. That just makes no sense.

Plus you're only 15. Just make it an occasional thing getting stoned with your buddies. Keep the paraphanalia like pipes and papers out of your house completly, and if you do get a sack, keep it small and on your person.

Respect their home and seek out some help. These are not common signs a parent shows when they "hate" their son. You're going through typical teenage angst. Talk to a doctor, throw on some Simple Plan, and cry your day away if that helps.
