You have enough on your plate without having to deal with an addict. Stick to your guns sweety, it doesn't get any better. I am going through a similiar thing with my 34 yr old son with pot. He thinks if he pays his bills whats the harm.......here every penny he spends on that is less money he has for other things, plus with the new mouth swab tests & hair follicle tests soon coming its going to be impossible to keep or get any kind of job.
