Would you date someone with a drug habit? While some can control and function while doing their drug of choice others have a hard time navigating life and dealing with their habit.
I've dated both kinds of guys. A weed head that smoked so much I never knew when he wasn't high. However he could function, he got up and went to work, and did everything else he just happened to smoke a lot of weed.
The other guy not so much. He was a coke head the lied, cheated and stole to get a high and it killed our relationship. What about you?
