Genetic Influences on Addictions

Issue in Context
Drug abuse and addiction are persistent problems in the United States. While environment plays a significant factor, genetics predetermines susceptibility to the development of addiction. A predisposition to addiction is evidently controlled by several different genes, allowing for a complex range of addictive traits. Though a large number of genes are involved in addictions, it is important to realize that the presence of these genes does not guarantee addiction; genotype does not dictate phenotype.
For example, one study estimated that 40 to 60 percent of cases of alcoholism stem from genetically influenced addiction. Other significant factors include environment, gender, age and ethnic group.
Due to the multifaceted manifestations addiction takes, there is no single medication that can be used to treat the disorders. Pharmacogenetics, the study of genetic factors that influence how a patient reacts to certain treatments, allows researchers and doctors to better choose the most effective treatment available for each patient. Every day new advances are made in the development of such methods.
