Substance Dependence: Common Myths
Substance Abuse Add comments

Drug dependence is simply a failure of will or of strength of character.

Dependence is a brain disorder and people with drug dependence have altered brain structure and function. It is true that dependence is expressed in the form of compulsive behavior, but this behavior is strongly related to brain changes occurring over time, with repeated use of drugs. In recent years genetics was found to be associated with the predisposition of individuals to be more or less susceptible to develop drug dependence.

People who have drug dependence can easily move back to occasional use.

Drug dependence is difficult to control due to compulsive drug use and craving, leading to drug seeking and repetitive use, even in the face of negative health and social consequences. Once dependent, the individual often fails in his or her attempts to quit.

It’s not worthwhile to invest in treatment for individuals who have drug dependence - it is a waste of time and money.

Investing in evidence-based treatment for substance dependence decreases negative health consequences and social effects (e.g. crime, economic burden and HIV infection). For every dollar spent on treatment 7 dollars are returned in cost-savings. Treatment is proven to be cost-effective in both developed and developing countries. It costs less than imprisonment.
