By inhaling addictive chemicals, you put yourself at risk of tobacco dependency and all of the short-term and long-term health problems that can dizzyy along with it — including lung cancer. As Ehringer notes, one long-term aim of such research is to help identify those who are at higher risk of nicotine addition.
But the complexity is also what makes behavior unique and interesting. Along with prior studies, they help identify genes that contribute to nicotine addiction. Though tobacco use has declined in recent decades in the United States, about 20 percent of U. New studies are revealing that the first few cigarettes an adolescent ever smokes have a huge impact on whether or not he or she will become addicted.
They reported that people with certain duzzy nicotinic receptor genes on chromosome 15 were more likely to become addicted to tobacco, more likely to smoke more cigarettes daily thereby worsening the addictionand more likely to develop lung cancer. The scientists could not determine if the higher incidence of lung cancer were because of the genetic variation or because of the excessive smoking.
Handy, Jr. As Ehringer notes, in most cases, about half of the factors contributing to human behaviors are believed to stem from multiple genetic factors and half from multiple environmental factors.
This is a health threat that you and your friends should take very seriously. The risk of getting lung cancer — the deadliest type of cancer — is 20 times higher in smokers than in non-smokers.
Your risk of other health problems Smoking just one or two times can cause immediate symptoms, such as the coughing and raw throat that you experienced, as well as nausea, lightheadedness, dizziness and other unpleasant feelings. Those who recalled feeling extremely dizzy after smoking were more likely to harbor a specific genetic variation in a nicotinic receptor gene CHRNA Smoking also causes cancers of the mouth, throat, voice box, esophagus, pancreas, kidney, bladder, stomach, cervix and blood leukemia.
But those who are predisposed to an addiction might be attracted to such intense feelings, even if it the feelings seem out of control, she adds. Inthree groundbreaking articles appeared in the journals Nature and Nature Genetics. Although the exposure probably was not enough to give you lung cancer, your smoking very well may have contributed to your cough and that raw feeling in your chest.
This means that genetic susceptibility to tobacco dependence does not doom people to addiction or disease.

Could I have lung cancer? These genes are also implicated in alcohol dependence and chronic obstructive pulmonary disease. Each time you smoked, you exposed your body to cancer-causing chemicals.
Centers for Disease Control and prevention. Other problems you could experience after just a couple of smokes include: Wheezing, due to constricted airways Increased phlegm production. Your risk of getting these cancers increases with each additional cigarette and each additional day that you smoke.
An even more dangerous consequence, however, is that it put you at much higher risk of developing a lifelong addiction to tobacco, which could set you up for a lifetime of health problems. Genetic research on tobacco dependence has blossomed in recent years. The test subjects were asked if they experienced—and how intensely they experienced—any of eight feelings: pleasant sensations, unpleasant sensations, nausea, relaxation, dizziness, pleasurable rush or buzz, coughing or difficulty inhaling.
The findings add depth and clarity to an emerging picture of genetic vulnerability to tobacco addiction. It included smokers and people who had smoked at least cigarettes in their lifetimes but had not become dependent on nicotine. Studies of younger people, including studies of adolescents before smokiny start smoking, are logical next steps.
Dizzy after first smoke? your genes might be ‘loaded’
The amount of these chemicals that you exposed yourself to was comparatively small, so the chances that you got lung cancer from those two experiences are very small. The work of Ehringer, Zeiger and other scientists employs new methods of associating subjective human experiences—such as dizziness—with specific genetic variants. But researchers have amassed a rapidly increasing body of knowledge linking these genetic variants to tobacco addiction, responses and disease.
