Short and sweet that's all I can be at the moment...

My best friend just got out of prison a year ago (for marijuana).  Now I think he's using meth, but I don't know how to prove it before I confront him.  And YES I have to prove it before I confront him.  He hasn't been using long I know that, but I think he is using now.  No real signs, just a hunch.  every few nights he stays up all night after he comes back from his friends house. He doesn't act like he's on drugs or anything.. he knows he has to hide it from me well.  I am around drug users on a regular basis for my job so normally I can spot them..
