Don't start with the habit of smoking

Doctors would always tell people to avoid smoking as it leads to all sorts of diseases from cancers to emphysema and even eye problems like macular degeneration, but it's pretty difficult to actually convince people who are already deep in the habit of smoking to stop. While there are now nicotine patches and medications which aim to help wean a person off tobacco, it's not a guarantee. That's why it's best not to start with the habit of smoking. Cigarettes contain nicotine, which is addictive, as well as huge numbers of other substances that contribute to destroying your health. I am not sure if electronic cigarettes is a substitute that would help in cutting down. One thing I know for sure is that don't start with the habit if you don't have it yet. That goes especially for young people who may feel invincible about doing "adult" things like smoking and drinking. It simply is not worth it.
