Yes, anytime you don’t take the medication as prescribed it is considered abuse. You can really get addicted to any drug, but big ones for abuse are painkillers (oxycontin, percocet, etc) and anti anxieties (xanax, valium, ativan).

It has come to my attention that a lot of smokers I know also happen to be heavy drinkers. I was just wondering whether the two habits are really connected. Will undergoing treatment for alcohol abuse also get rid of the person’s smoking habit?

My friend said that it is fine to try illegal drugs as long as you will not continuously use it. This is why he keeps on persuading me to puff some marijuana. However, I told him that a small amount of illicit substance would be very harmful for the body. Besides, it will lead to even bigger problem and greater addiction. I want to convince my friend using factual info, but I am not so sure about the stages of substance use. Can you help me?

I was just wondering about this since the smokers I know also drink excessively. Is there really a connection between smoking and drinking alcohol?
