A smoking addiction means a person has formed an uncontrollable dependence on cigarettes to the point where stopping smoking
would cause severe emotional, mental, or physical reactions. Everyone knows that smoking is harmful and addictive, but few
people realize just how risky and addictive it is. Having a smoking addiction does not mean that you cannot stop - only that
it is likely to be difficult. Nicotine is a psychoactive drug with stimulant effects, which causes smoking addiction.
