There are four stages of addiction: fooling around, being hooked, hitting bottom, and recovering. Dr. DuPont acknowledges that there are many who can go no farther than the first stage, but he does not recommend it. Anyone can become addicted to the many reward-producing substances because of their profound effect on the pleasure centers of the brain. Everyone has those centers, but there are personal and environmental risk factors that heighten the danger of becoming addicted. Youngsters with character disorders are prime candidates for addiction and should never experiment with alcohol or other drugs. Families need to be vigilant and have a clear plan for dealing with the threat of nonmedical drug use by the children, including clear expectations of abstinence. Parents also need to establish the consequences, within the family, of failure to follow the rules.
