Mate is addicted to Methamphetamine

[johnydep]

My best mate is going through a messy divorce, both he & his ex smoked ICE and always said it was only for social occasions, but now there relationship is absolutely rooted and to the point of having me & his family worried about his well being (as in suicide).
Today was panick stage, know one knew were he was. I was with his family discussing things, but I did not bring up his use of ICE. They know something is wrong, but they think it is the break up of the marriage (children involved) and the stress of it all.

I want to tell, but I know that this will cause him to withdraw from everyone and I'll not be able to reason with him like I am now.

He was at home, I had to jump his fence & wake him up.

When I left his place he was going out to his dealer, I laid down my thoughts & feelings to him about what the stuff is doing to him. Told him it is making him angry & aggresive, which is not looking good for his chances with the kids, courts, cops.
He reckons he's not addicted and the stuff helps keep him calm, I told him 'bull', and a lot of other things. Told him that they all say that.

He loves his kids, but he is loosing them and this makes him angrier & depressed, (his wife is a nutter, was using ICE as well and may still be using it) but he thinks the ICE keeps him calm & level headed. Of course it does, when your coming down!

I told him to make this his last score then dry out for a month & see how he feels, because 'your brain is distorted, once it is clean you'll be able to think clearer, think of how you can get the kids, with out that stuff in you'.
He said he understands what I'm saying.

Should I give him a week & see how he is doing, or should I tell his family?

This f*&ks me right up, I feel like grabing his head & smaking into the wall & saying "WAKE UP".

You don't have to answer this, just needed to get a bit of it out of me.
