Drug addiction is something that can start out small and spiral out of control. It's a condition that a person may not realize they have until it has really done damage to their life. For most people, drug use starts out with experimentation. A person may then start using drugs a couple times a month. The drug use then advances from a couple times a month to a couple times a week. It can then become more frequent than that. As drug use becomes more frequent, it can start causing problems with a person's life and health.
One reason people avoid drug treatment is because they are functioning addicts. A functioning addict can hold down a job and even maintain relationships. The illusion that everything is under control is what makes a functioning addict not see that they indeed have a problem with drugs or alcohol that needs to be addressed. Although they might not be having a problem with their job or relationships, an addict may be seriously hurting their health with their substance abuse. Letting a person who is a functioning addict know about the health consequences of addiction is one way to get them to seek out the treatment that they need.
After a person gets in trouble with the law, they may realize that they need to enter a program for drug treatment. In some cases, a program will be mandated by the court. For example, a person who is charged with domestic violence may have to enter an alcohol program if it is believed alcohol use contributed to the act of domestic violence. Attending an alcohol program may also be part of a plea agreement to resolve a DWI case. A charge of possessing drugs can also result in some form of drug rehab.
It's important for a person to complete a drug rehab program in its entirety. Simply just attending a few meetings isn't enough to beat addiction. One of the best things about being in a program is the ongoing support that a person can receive. Having a mentor to talk to about issues is one of the best things about seeking out help from others.
