Help please! Is drug addiction formed the same way as alcohol addiction or any other addiction?

Yes. Yes often drug and alcohol addicition starts as a poor way to cope with stress and low self esteem and as reliance and use of these agents continue- an addiction is started. But it is important to note that addiction has a strong genetic component as well. Often this is reflected in strong family history of addiction. In any case seek help from your dr if you have an addiction.
