problem as well as substance abuse.
“The complex nature of drug dependency, involving many behavioral and environmental factors, indicates that any genetic component acts in consort with other nongenetic risk factors to contribute to the development of substance abuse and addiction. Thus, the presence of a genetic factor does not ensure drug addiction nor does its absence guarantee protection from drug addiction. To date, much of the work done in this field relates to alcoholism. Less is known about the genetic aspects of the abuse of other drugs. Animal studies have established that genetic factors contribute to alcohol preference, the reinforcing actions of alcohol, alcohol tolerance, and alcohol physical dependence. While few studies have examined the genetic component vulnerability to the addictive properties of other drugs of abuse, evidence from animal studies confirms the role of a genetic influence on the use and abuse of drugs other than alcohol.” (Herdman, R, 1993, p. 12).
Besides genetics the environment can play a part in alcoholism. The people you hang around with, the type of job you have and the household you were raised in can contribute to if you drink to relax or not. If you were raised in a home where you mother/father/parents drank when they got home from work then you are more likely to do the same. If you were raised where there was never any alcohol in the house you are more likely to not drink to unwind. That also goes with the people you hang around with if they are drinkers you are more likely to have a drink then if you hang out with people who do not drink.
