Students are more likely to smoke than the general population and there can be a social pressure to smoke, but there are some serious impacts on your health of doing so.
Tobacco smoke is nasty stuff. It contains over 4000 chemicals, many of which are harmful. Tar accumulates in the lungs and contains cancer causing chemicals. Carbon monoxide reduces the amount of oxygen in the bloodstream, reducing lung efficiency. Nicotine is what makes the tobacco addictive.
Smoking increases the risk of lung cancer and heart disease. It ages the skin, discolours nails and can cause infertility.
There are many ways to get help with quitting smoking. Electronic cigarettes and vaporizers are becoming more developed but are less highly recommended as a quit aid as they retain the addiction to nicotine and the smoking action, so going back to smoking is more likely.
Nicotine patches and prescribed medication can really help, as can alternative treatments such as hypnosis.
Willpower to stop is still needed and university or college could be a fresh start for you and provide the motivation to quit. It also may provide a financial incentive when you add up the cost of cigarettes alongside the proportion of student loan left over for social activities.
If you need help stopping smoking, there are free Stop Smoking services available from your GP.
