Does genetics play a role in smoking cessation?

Various studies conducted to find out if your genes make it difficult for you to quit smoking, have revealed that that is in fact the truth. Scientists have even discovered three genetic areas that are thought to be associated with your habit of smoking - one is considered to be linked to smoking initiation and one with smoking cessation. The third area, a variant on the chromosome 15, is related to heavy smoking; this is the area that contains the nicotine receptor genes and is related to nicotine dependence.

The findings were concluded by examining the phenotypes of 74,053 people. But the results of this study have yet to translate to a clinical setting. Through this study, the researchers are trying to come to a conclusion wherein the results can be used in the near future to predict the effects of different smoking cessation treatments on different people. But, until this becomes possible, all smokers should be encouraged to quit smoking by whatever means possible. Prescription drugs like Zyban and Chantix varenicline are known to play an important role in smoking cessation.

Quit smoking drugs

Most smoking cessation drugs have nicotine in them, but with the use of Zyban or Chantix varenicline you can avoid nicotine altogether. Both these drugs are prescription medications and therefore caution is mandatory. Available in the form of pills, Zyban received approval in 1996 and ten years later Chantix varenicline was given the go ahead as clinical trials revealed that it effectively combated nicotine addiction.

Chantix varenicline works on the nicotine receptors in the brain, reducing both the physical and mental pleasure received from smoking, as well as the withdrawal symptoms associated with nicotine withdrawal. Zyban is an antidepressant pill that helps control nicotine withdrawal as well as the cravings for nicotine. However both these medications require careful monitoring by your doctor, so that you derive complete benefit from the use of these medications.
