There are dangerous devices found all over the world today that will kill over 500 million people in the next 50 years. They are not land mines or nuclear bombs. They are highly engineered drug delivery systems designed to addict the user. They are called cigarettes and they are legal. The Ontario Medical Association (OMA) considers tobacco dependence to be a progressive, chronic disorder. The OMA has developed a position paper to dispel some of the myths associated with trying to stop smoking. I provide for you a summary of some of the common myths. Keep in mind that the cigarettes are far more than rolled tobacco in paper.
1. Nicotine is the harmful substance in cigarettes. False. Nicotine is the addictive substance in cigarettes. Among the thousands of toxins produced in the combustion process at least 40 are known to cause cancer. Among them are bensopyrene, arsenic, nitrosamines and vinyl chloride. Nicotine does not cause cancer.
2. Nicotine addictive potential is the same, no matter how it is obtained. This is false. Cigarettes are far more addictive than nicotine patches. Inhaling nicotine smoke allows a quick and large hit to the receptors in the brain, while when using a patch, the delivery across the skin is slow and controlled. It is able to calm the craving without an addictive potential. Similarly, nicotine gum is chewed slowly and the transfer of drug occurs across the mucus membrane in your mouth. The newer inhaler device actually delivers a spray onto the oral membranes, again keeping delivery uniform. It reinforces and modifies the behavioral aspect of hand to mouth gestures common to smoking.
3. Nicotine replacement therapy (NRT) is safe for smokers. True. There are no toxins in patches, delivery is controlled and non-addictive, and side effects are extremely rare.
4. Smoking while using NRT causes heart attacks. Smokers are already at the high risk mark for heart attacks and strokes. These health hazards are the result of other toxins in cigarette smoke and not nicotine. This myth has been dispelled many years ago.
5. Patients with heart disease should not use NRT. Continuing to smoke is more dangerous than using NRT. Smoking promotes thickening of the blood which leads to clots. Nicotine is a stimulant that can aggravate things but is not the cause. Combining smoking cessation medication with NRT is a strategy worth trying by all smoking heart patients.
6. Pregnant women should never use NRT. Cigarettes increase the risk of abortion, prematurity and low birth weight. It is better to use NRT than to smoke during pregnancy. Second-hand smoke should also be avoided in pregnancy.
7. Teenagers should not use NRT. Also false. The under 18 crowd represents the largest group of new smokers. It is worth targeting a bad habit as soon as it is recognized.
Many people still feel that it is their “right” to share deadly toxins with those around them. It is a misguided inference that simply being able to legally purchase something implies that society has accepted that one can use it as one pleases. Apart from a cough, smokers don’t see consequences of their actions for years. They too often assume that medical science can treat any symptom they develop and can start with a “fresh” bill of health any time that they choose. It is a frustrating part of many doctors' day to inform people that they are afflicted with a smoking associated disease. Please don’t make my day!
