<p>Yes. All tobacco products. It’s a naturally-occuring insecticide poison in the tobacco plant. It’s more lethal than strychnine, dose for dose.</p>
<p>It is possible to remove nicotine from tobacco, but then nobody would smoke. The only reason for smoking is nicotine addiction. There are no benefits to tobacco otherwise. The reason tobacco use spread around the globe is the intensely addictive nature of nicotine.</p>

<p>Yes, there’s probably a genetic predisposition. However, nobody should take any comfort from that in terms of thinking, “oh, I won’t get addicted.” Basically, if you smoke, you should be prepared to accept a drug addiction that can last decades if it doesn’t kill you first. Research has shown that it is even more addictive for teenagers due to some brain chemistry issues.</p>
<p>BTW, nicotine works on a specific group of receptors in the brain, causing a release of dopamine in a mechanism that is virtually identical to heroin addiction. As the addiction takes hold, the number of those receptors increases. The addict goes into withdrawal without that dopamine release. That’s what creates the false impression that smoking “relieves stress”. The only stress being relieved is the stress from falling nicotine levels. Of course, there’s the Catch-22 of drug addiction. Relieving the “stress” from the nicotine wearing off from the last cigarette causes the “stress” that requires the next one.</p>
<p>Nicotine withdrawal is actually pretty mild, about like a bout of the flu. What makes it so insidious is the wildfire speed with which the addiction can be reestablished. People quit for months, years, even decades, think they can smoke just one, and end up almost immediately back at their full pack or two a day addiction. It’s an all or nothing proposition, something that can only be grasped once smoking is properly viewed as a powerful drug addiction. Since there is not a single benefit from smoking, the obvious policy for any young person is a simple zero-tolerance policy - never put any nicotine in your body.

<p>That is completely false. Actually, hookah smoking has more of everything bad in cigarette smoking including nicotine.</p>

<p>Nicotine is not just addictive, but breathtakingly addictive, regardless of the source. Cigarettes, pipe tobacco, cigars, hookah, snuff, chewing tobacco, nicotine gum, nicotine patches, nicotine lozenges. All highly addictive. Just like with cocaine, the delivery mechanism is more efficient when the drug is smoked (nicotine from a puff on a cigarette or hookah hits the receptors in the brain in just eight seconds), so the smoked versions of the drug produce a more faster, more intense brain chemistry reaction. However, there are fully-addicted long-term users of smokeless tobacco and nicotine gum.</p>
