Addicts have one focus in their lives, and that's using drugs. They may have when been a delicate, caring individual, however as dependency takes hold this pertains to an end and they're egotistical and entirely driven by their desire to continue using. The disease of dependency is a difficult and complex one, and it ultimately alters the brain of the addict, which is why they act out in certain ways and become so concentrated on their dependency.Addiction can be deemed a chronic disease, and with treatment it is workable, and the addict can live a fulfilling life, but you have to know most importantly that you can't force someone into treatment, nor can you do the work of recovery for them.
