Nicotine is a poisonous alkaloid found in all parts of the tobacco plant, but especially the
leaves. A colorless, oily fluid when pure, it becomes brown with the characteristic tobacco
smell once exposed to air. Nicotine is one of the most toxic and addictive of all poisons.
The absolute amount of nicotine in each cigarette is 8-9 mg and represents 1.5%-2.5% of the
weight. Blood nicotine level rises within 10-15 seconds after each puff. Cigarette filters
reduce exposure to tar, but not to nicotine. Smokers generally experience withdrawal
symptoms once their daily nicotine levels fall below 5 mg. Nicotine is an extremely toxic
substance that acts as quickly as cyanide. A fatal dose for an adult is estimated to be less
than 5 mg/kg body weight.

![]() igarette smoking is perhaps
the hardest addiction to kick. Ask any smoker. Many researchers equate nicotine addiction
to heroin. While there are countless "stop-smoking"
products and techniques out there, as the saying goes "You're not going to quit until YOU
want to quit." With all the information available on the dangers of smoking, including nicotine
addiction, lung cancer, low-birth weight for infants, and secondhand smoke-related cancers,
it's surprising that anyone still does smoke. Regardless, there are plenty of us
who "really want to", but realize the difficulty of just putting them down. ![]() ![]() |
