Here are some links to scientific theories/proof about addiction having a genetic relationship:

Researchers have discovered that one of the genes is responsible for the sensation of pleasure. Roughly 10 percent of the population has a variation of this pleasure-seeking gene, known as the A-1 variation. People with the A-1 variation have fewer receptor cells in the brain for dopamine, the chemical associated with pleasure. That may inhibit their ability to feel “normal” levels of pleasure. Addictive behaviors boost the production of dopamine, which may increase stimulation to those few pleasure receptors. Investigators have found 50 percent of patients with addiction problems have the A-1 gene variation. The researchers theorize the need for pleasure-receptor stimulation may lead to the development of addictive behaviors.
