Addiction is defined as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, despite harmful consequences.† It is considered a brain disease because drugs change the brain-they change its structure and how it works. These brain changes can be long-lasting, and can lead to the harmful behaviors seen in people who abuse drugs. Contrary to many of you alls beliefs a Drug Dealer could be anyone. Successful drug dealers actually don't fit the "Norm" description. Normally the low dirty trashy dealers don't get far in what they do because they are not educated enough to keep the ball turning. A good drug dealer runs the streets or college campus in a business like form using micro-economics or proven statistics to enforce a safe and gurantee'd profit. A good drug dealer knows his limits. Meaning that if the kid is a fien you don't sell him enough to overdose or cause bodily harm that effects the rest of his life.
