I am 15 years old. My boyfriend is 16. He has lung cancer. I've tried to convince him to stop smoking and he's told me he's going to try but he's not going to stop smoking pot. I care about him alot and it hurts me. I smoke too. Is it selfish for me to ask of him to quit? My veiw on the situation is I'm not quiting till he quits. I feel ******. I don't know what to do cause I'm woried all the time. I doubt he'll ever stop smoking pot, not that I'm an anti-drug finatic -I smoke too- I just really care about him and I need suggestions on what to do and how to help, and what I should do & should I try to help at all?
