Now although this has it's benefits; money for him (and a fair bit of it), I can get the drugs I want etc. I'm quite concerned about him.

I was having a drink with him last night and he was walking around with a packet of cigarettes containing about £450 worth of Ketamine and I know he's looking into getting some acid in a bottle soon.

He asked this guy who he didn't know but just suspected he might be interested (heard him mention the drug in question) and made a sale. I'm worried this could end really badly, selling drugs isn't exactly the safest way of making money.

I don't really know if there's anything I can do about it.
