Nicotine doesn't cause one lose control of one's sense and doesn't endanger other people.
Yes it does...I lost control of my ability to regulate my own behavior due to nicotine. For 20 years, I HAD to have a cigarette. I could not live normally w/o it. I had to carry them w/ me everywhere I went, 'cuz it would be only a few more minutes before my body would begin to crave another one. I was controlled by the craving for nicotine--I was a complete drug addict that could have used the $ I spent for tobacco on more important reasons.
