Is Internet addiction genetic, just like nicotine addiction?

That's the theory among German researchers who evaluated 132 people with signs of being hooked on the Web.

The study authors conducted a genetic analysis and discovered that the people with Internet addiction were more likely than others to have a genetic mutation on a gene known to play a major role in nicotine addiction.

The study, recently published in the Journal of Addiction Medicine, finds an association between the gene mutation and addiction but does not prove a definitive link.
