Addiction comes in two forms: psychological dependence and physical dependence. Psychological dependence occurs when a a person feels that they need a particular substance in order to function properly, to feel comfortable, or even just to cope with day-to-day life. Physical dependence happens when the body becomes tolerant to the presence of the addictive substance and requires more and more of that drug in order to maintain the same effect.
Few people who suffer from addiction receive the treatment they need, often because of the stigma that surrounds addiction itself. Through public education, we can help people understand that addiction is a treatable illness, not a moral failure. By raising awareness, we can help save lives.
