In cigarettes, there is this substance called "nicotine." This substance is the reason for addiction. It causes your brain to feel relaxed whilst smoking, then for a while after you remove the cigarette, you feel happy and relaxed. But, this doesn't continue. After a while, it stops and is replaced with feelings of nervousness, anxiety, and anger as well as many other uncomfortable emotions.
These emotion cause the smoker to want to relax, therefore, they grab another cigarette.
Cigarettes are very harmful to one's body. They can cause skin cancer, lung cancer, and teeth problems. See anyone with bad yellow teeth and bad-smelling breath? It is most likely that they smoke. Though, not everyone who smokes gets sick. There is this thing called "second-hand smoking" that occurs when a person is around a smoker. It happens because the non-smoker breathes in the fumes and smoke of the cigarette the smoker is smoking. It is juts as bad as normal smoking.
Now, you might think eCigarretes are good for you...but they are not! They cause almost- if not exactly- as much harm to your body that a normal cigarette would.
Never try smoking. It will lead to an addiction that is neither attractive, or healthy!

Another, simpler way of asking this is : do exercise programs have the same effects on different people? Do different people need to pay attention to different conditions? The answer is: yes, and that's because different people have different levels of physical fitness at the beginning of the regine, so some people might be able to endure harsher exercise than others.</span><span />
