Found that first degree relatives of pathological gamblers were more likely to suffer from pathological gambling than were more distant relatives, thus demonstrating a strong genetic link

Measured gamblers' cortisol levels before and after seeing video of their choice of gambling and a video of a neutral stimuli. Recreational gamblers had increased cortisol levels after both videos. PG's had no cortisol increase

There are individual differences in the need for optimal amounts of stimulation. Sensation-seekers have a lower appreciation of risk and anticipate arousal as more positive than do low sensation-seekers. So more likely to gamble

Poor tolerance for boredom may contribute to repetitive gambling behaviour. PG's have higher boredom proness scores than a control group of non-gamblers.

Studies 1,572 twin pairs. Found that both males and females individual differences were explained by genetic (44%) and environmental (56%) factors

Reported that nicotine dependence was influenced primarily by genetic factors (75%). This suggests that regular tabacco use is linked to individual differences in nicotine metabolism.

Biological - Smoking - Maintenance - Xian et al
Carried out a twin study to test whether genetic factors contribute to failed attempts to quit smoking. They found that 54% of the risk for quit failure could be attributed to heritability
