Why are cigarettes addictive?

[Ross Taylor]

Nicotine is the only thing in cigarettes that causes addiction..!!
But one can quit smoking easily if he mentally prepare himself for quitting it and also use one of those nicotine products like nicotine patches,gums and tablets which will help them to keep away from you..!!

Basically the people who smoke are idiots who have been addicted since an early age. They smoke because they were showing off when they was a child and thought that cigerettes made them look like an adult. They carry on smoking. Spending all of their hard earned cash on ciggies.
The more intelligent of us took up beer as an addiction.
