Alcohol and tobacco are frequently used together and may share certain brain pathways connected to dependence. Both alcohol and nicotine trigger the release of a neurochemical (dopamine) which is connected to pleasure and reinforces the use of these chemicals. It is also being demonstrated that the use of each drug affects our ability to tolerate the other. Tolerance is our ability to decrease our sensitivity to the toxic effects of a drug so that we are able to use more without immediate negative results.

Unfortunately, the use of alcohol and tobacco can be more harmful than the use of either individually. Both contribute to increased risk for lung and cardiovascular diseases. The risks of cancer of the throat, mouth, or esophagus are greater for the smoker/drinker than for individual use of either drug. The risk of developing throat cancer is approximately 7 times greater for smokers, 6 times greater for drinkers, and 38 time greater for users of both.

Alcohol use increases liver activity which causes the release of certain enzymes. These enzymes interact with some of the 4,000 different chemicals generated by tobacco use and convert them into chemicals that can cause cancer. Alcohol can also act as a solvent when it interacts with tar in the bloodstream, contributing to its further distribution throughout the body. Additionally, many people who abuse alcohol also are deficient in certain vitamins and minerals that offer some protection against cancer.

While the use of either drug may increase your risk of health problems, the combined use seems to be even more deadly. If you would like some information about how to reduce your risk, please call Dennis McNamara at Asante EAP, (541) 608-4238.
