Is Cocaine Addiction Genetic?

Cocaine is a widely abused drug in the United States, some side effects include:

1. Changes in blood pressure

2. Nausea

3. Vomiting

4. Loss of appetite leading to malnutrition and weight loss

5. Cold sweats

6. Restlessness and anxiety

7. Damage to nasal cavities

8. Damage to lungs

9. Possible heart attacks, strokes, or convulsions

New research shows that there may be a gene that causes some people to become dependant on the drug, and to get feelings of paranoia, while others appear to be able to use coke on a more casual basis. For all the nitty-gritty science behind the study, check out this article.
