Why do some people become addicted, while others do not? Studies of identical twins indicate that as much as half of an individual's risk of becoming addicted to alcohol, or other drugs depends on his or her genes. Pinning down the biological basis for this risk is an important avenue of research for scientists trying to solve the problem of drug abuse.

Genes – functional units that make up our DNA – provide the information that directs our bodies' basic cellular activities. Research on the human genome has shown that the DNA sequences of any two individuals are 99.9% identical. However, that 0.1% variation is profoundly important, contributing to visible differences, like height and hair color, and to invisible differences, such as increased risk for heart disease, stroke, diabetes…and addiction.

When an drug addict is finally willing to admit that they are completely powerless over their addiction and need help recovering, they are left with a choice.

The choice of finding the right drug rehab facility.
