It's been suggested that gambling can be intitate through the levels of dopamine within the body
When an indidivdual engages in an addictive behaviour such as gambling this raises dopamine levels, creating an acute stressor which endures a nature high
To recreate this biochemical high and individual is likely to replicate this action again
Demonstrating that initiation of gambling can be due to dopmaine

D2A1 AO2
To support this researchers have investgated the influence of the gene D2A1 in pathological gamblers - which regualtes dopaminelevels
They found that in these gamblers this gene was defective and in gambling addiction
Therefore suggestsing that we are prediposed in developing an addicition

Breen AO2
Suggetsed that this explanation was inaqueate as it doesn't explain why some people develop addicitions faster than other
They found that it took a year for people to become addicted to video gambling where as it took 3 years for people to become addicted to horse racing
Therefore suggesting that there are other factors influencing addiction as the biological explantion can not explain why people develop addicitons at differant rates

INITIATION SMOKING A01
Researchers have suggested that the gene SLC6A3-9 can explain why some people develop addicition
This gene is used to maintain dopamine levels and usally reframes people fromengaging in amoking
It's believed people who do not posses this gene are more likely to develop smoking addiciton
It's also believed that smoking can be intitatted through addiction
It'sbeleived that the influence of genetics can range between 30-80% of people

Suggested there is a biological link that prediposes us to become more likely to dvelop addictions however also suggested that other factors may enhance the likeihood of this
