I think it's important to realize that not all drug use is drug abuse. These days, drug use and drug abuse mean exactly the same thing, but it shouldn't be like that. Someone who uses drugs isn't necessarily a drug abuser. Someone who neglects their responsibilities, family, does unsafe things, uses unhealthy amounts of drugs, etc, is a drug abuser. Someone can do drugs and not ABUSE drugs. It's the same as someone who drinks alcohol. Drinking alcohol doesn't make you an alcoholic.
