What do people feel when they smoke? Is it that sensation that makes them addicted to it?
Not necessarily. You should look into the chemical that actually causes addictions: dopamine. It isn't just the nicotine that causes tobacco addiction. Most smokers don't actually have a sensation when smoking a cigarette, but rather a relaxation (even though it's a stimulant). It has also been suggested that the modified breathing pattern of smoking actually adds to the addictive properties present in the chemicals. Weird stuff.
The same modified breathing pattern can actually give some light smokers the ability to produce more PSI through exhalation than non-smokers. Light smokers tend to breath deeper and somewhat more naturally in rhythm and consistency. Nicotine patches have an extremely low success rate as an aid to quit smoking. Drugs like Wellbutrin in addition to deep breathing exercises are supposed to be much more practical and successful than nicotine treatment (gums, patches, etc).
Sort of discussion goes way back. Idle did a good job describing but here is a more detailed version. But in general I completely agree with Idle. Human lives have no inherent purpose or meaning and it really doesn't bother me. You may want to look into philosophy if you are interested.
Or....
Human lives are the most precious of life and the only opportunity to facilitate spiritual change to realize the potential of your soul.
Depends on which book you read. ;)
