What are some signs that someone is a drug dealer?

[Anonymous]

I recently met this guy and I have a nagging suspicion that he may sell drugs. I have no real basis as to why I think this,I just have that feeling. but I'm sure and don't wanna accuse him. I could be wrong but idk...how should I know if someone is involved in the drug trade? What will give them away?

Lots of cash. No credit cards with drugs, so they will have more cash than most normal people would. They might also have more money and "things" than they should for how much they make working a job.

If they are selling from where they live, they might have a lot of people coming in and out and only staying a short time.

There's really no sign. You should just treat them as innocent until they actually open up their mouth.
