Drug and Alcohol Abuse
Research has established that some of the risk of addiction to both alcohol and drugs is inherited from your parents and grandparents. Children of alcoholics are 50 to 60 percent more likely to develop alcohol abuse disorders than children in the general population. Similarly, children of parents who abuse illegal drugs may be 45 to 75 percent more likely to do so themselves than the general public. This suggests that some of the risk factors for alcohol and other drug use are deeply rooted in genetics.
