Risk factors in the development of addiction: genetic vulnerability, stress, personality, family influences and peers
Some people are more likely to develop an addiction than others. Five key risk factors increase that likelihood: genes, stress, personality type, family behaviour, and the influence of friends.
Real World
Research on the DRD2 dopamine receptor gene found that children of alcoholics who carry the A1 variant are significantly more likely to develop alcohol dependence themselves, even when raised in non-drinking households.
