How to tell if someone is addicted to drugs (Pain Killers, Cocaine, and Nerve Pills)?

Question by ♥ι’м тнє gιяℓ ωιтн тнє тαzєя: How to tell if someone is addicted to drugs (Pain Killers, Cocaine, and Nerve Pills)?
What are the “symptoms” of an addict? I’m not asking how to tell if someone is using them. It’s obvious that the person snorts them daily. But how do you tell if they’re addicted to them?

Also how would you know if you/someone else is addicted to cocaine. It’s possible to do drugs without getting addicted to them so how do you tell if you/someone is doing them for fun or is in denial and really are addicted?
I’m not asking how to tell if someone DOES drugs. I know this certain person is doing them. But how to tell if someone is really addicted to them? (Just trying to make the question clear)
Amice—I don’t need info about other drugs. I already know about them. And sorry that I posted this question twice. My computer was being screwy.

well, if they start getting really angry and defensive about the drugs they are doing. When they start distancing themselves from people. When they start denying or hiding that they are doing drugs. There are tons of ways to know.
