The Costs of Smoking Humans are the only animals that intentionally inhale smoke. Humans have discovered many ways to inhale smoke, but no benefits are known. Cigarettes, the most popular method of inhalation, seem deceptively basic, just a paper cylinder containing processed tobacco. In fact, they are specifically designed to deliver a consistent dose of nicotine, sourced from the three main types of tobacco, Virginia, Burley and Oriental, which each contain varying levels of nicotine. Cigarettes also contain thousands of other chemicals, although some may seem harmless, such as sugar, chocolate and vanilla, which are added to make the smoke smoother and easier to inhale. However, even these harmless substances can become toxic when combined with other substances. Many studies have been conducted by medical professionals to study the effects of inhaling smoke, nicotine, and chemical cocktails on our bodies. The physiological cost of smoking is borne by the highly addictive nature of nicotine, which makes it difficult for the smoker to quit. This will be examined later in the trial, as well as the reversal of harmful effects if the smoker quits. The numerous adverse physiological effects on the human body have been consistently proven over the past decades, including diseases of the circulatory and respiratory systems, various cancers and premature aging, which will now be discussed. There are various diseases of the circulatory system, which can be caused by smoking. related, the biggest “killer” being coronary heart disease. As soon as you inhale cigarette smoke, it affects your heart. Less than halfway through this article, the consequences of smoking are clearly enormous and indisputable, although this essay has only discussed the physiological effects. Smoking is also extremely expensive, not only in terms of the cost of the cigarettes themselves, but also the additional cost to health services that have to treat patients with smoking-related illnesses. It is becoming less and less socially acceptable to smoke in public, due to increased awareness of the effects of passive smoking. It is to be hoped that public acceptance of tobacco will decline until smoking becomes illegal in public. However, the addictive nature of nicotine cannot be underestimated and even legal measures may have little effect on smokers, as they have continued smoking for decades, knowing the harmful costs. www.ash.org.uk Kent M.
