People at risk

• Current data shows that people with insecurity, emotional dependence, or a passive-aggressive attitude are more likely to become addicted to drugs.
• The researchers have not yet found an “addiction gene”, but nevertheless believe that a genetic factor may be involved. People who have a genetic deficiency in the dopamine D2 receptor appear to be at greater risk.
