A
latest clinical finding proved that the genes play a crucial role in
determining an individual's ability to quit smoking or not. This research
evidence further claimed that the same genetic variations are responsible for
providing information regarding an individual’s response to nicotine
replacement medications.
The study volunteers collected the information from around 6,000 smokers and
compared the ability of every individual to cease smoking with genetic
predisposition, which was further associated with the
increased tendency of nicotine dependence and their smoking.
Association between smoking and genetics established
These genetic variants were found to
posses the potential to predict the effect of the use of smoking-cessation
medications and the response of an individual to them. Individuals associated
with a higher risk genetic marker smoked for an average period of more than two
years as compared to those without the similar higher risk genes. The same
individuals were found to be less liable to quit smoking without the use of
anti-smoking drugs and were thrice more susceptible for quitting smoking with nicotine patches or gums,
antidepressant medications and other potential drugs. The study was found to
lay groundwork for the mysterious nicotine addiction puzzle.
