I'm 19 and started doing coke not religiously but mabye every Saturday night for about a month.
I've gone with out it for about a month and feel no need or want toward it. It's not like you said for everyone. I had never touched the stuff before like 3 months ago. No I could care less about it and if I never do it again.
It didn't take me long to 'get back to normal' seeing as a good sleep and shower made me feel better after.
Just pointing out that it's not as bad as your putting it for some people. It doesn't make you not function for weeks after?
For me I was fine the morning after and could do everyday thing, work, etc.
But again, I havn't touched it in a month and could care less to.
Just putting in my opionion.
It is good that she doesn't have really any responsibilty right now. And she will probably grow out of this phase she's in or od and die...?
Either way I'm sure she knows what she's doing, if that's what it is. And maybe she will straighten out and look back on it and laugh.
