Addiction is the compulsive use of habit-forming drugs for their pleasurable effects.
Pain relief is a medical reason for taking narcotics or any other drug.
If medicines are taken under medical supervision, the chance of addiction is very small. Although some drugs may cause side effects, most can be successfully handled. If you are experiencing such problems, discuss them with your doctor. Not all pain medicines are narcotics. However, any medication can be dangerous if they are not taken properly.
