I would be just as worried about a friend drinking every night. And being stoned around non-stoned people, isn't a sociable thing.. She just gets really.. Well, depressed. She's never very happy or fun when she's been smoking, which I realise not everyone can be happy all the time, but its only when she's smoking.
We had a chat last night, a really long one. She said she's gonna try and not do it anymore, because she doesn't even know why she's doing it. But now I feel I've forced her to do something she doesn't want. Or, to not do something she does want too. I realise she's doing this to please me, because she doesn't want it to come between us, and she got quite upset when I wouldn't see her because she was stoned.
And in reply to Mad4it_87, it does change how people are. The same as alcohol does. She doesn't change entirely, her "basic" personality is still there, but she just gets more pesimistic about everything, she just can't see the good about anything. It doesn't make her more sociable, and in my opinion, I don't know anyone who is more sociable when they're stoned. I don't agree that alcohol is an un-sociable thing either. I never fall out with people over small things, or fight, infact I usually tend to make quite a few more friends when drunk. Being stoned seems to make people more withdrawn. But as I've said, being stoned a few times a week, or being drunk a few times a week - both can be quite worrying, especially if the reason they give is "to fill some kind of gap".
