I and my wife were cokeheads for about a year and a half, could'nt never get enough of it 50-80$ a day etc...... and one day we just looked at each other and saw what we were becoming and stopped right there.....best move I ever made in my life. that was like 5-6 years ago.
Now I just smoke my meds. and so does my wife LOL
Your friends need to really WANT help in order to use help, other wise your just wasting your efforts.
good luck-being where i am "babylon" meth is cheaper than coke and ive seen pretty much 90% of my old high school buddies turn into junkies and shit(after years of crystal and coke), or go to prison.
You have to accept your friends are becoming slowly not your friends anymore.
