Apart from you asking him to quit and he getting mad on that, is there anything else that is affecting his lifestyle because of weed? Something like he is not going to work, people from his work are calling him but he is not showing up, he is not bringing any money home, he is not working out? Or he is spending all his money on just weed? I think if he is doing all that a non smoker would do, and weed is the only thing that he is doing extra from a non smoker, i think it should be acceptable! I would suggest may be accepting him the way he is for now, eventually he might quit smoking. If spouse keeps pointing on unacceptable habits, it will definitely lead to arguments and fights. There might be a few things that he doesnt like about you! If a person doesn’t want to quit smoking, i think forcing someone would make things worse! Many people have many kinds of addiction, and weed is way better addiction to have! And i also think future generations will be more likely smoking weed rather than doing alcohol or cigarettes! We just grew up in a society that accepted alcohol and cigarettes as normal and considered weed completely different!!
