When we met three years ago he didn't smoke at all. Two years ago it started becoming a 'thing'. We had quite a few disagreements as I didn't want to be going out with him when he'd be stinking of the stuff (I mean, before going shopping or going out for a meal he'd have to have a joint).
It's got to the point from the minute he wakes up to the minute he goes to bed he's smoking. He's got a new job after being redundant last year so we're not able to say if he's able to hold it down or not.
He says that it's normal that most people smoke it.. nothing to be embarrassed over.
