Nicotine

It is the addictive substance in tobacco.

It is an extremely fast-acting drug. It reaches the brain within 10-15 seconds of being inhaled.

A teen’s brain is still developing, which can make teens more vulnerable to becoming addicted.

Nicotine is found naturally in some plants but is also manufactured.

Carbon Monoxide This is a poisonous gas that has

no smell or taste. The body finds it hard to

differentiate carbon monoxide from oxygen so it absorbs it into the bloodstream blocking the oxygen from getting in and making it hard to breathe.

It is also found in auto exhaust.

Benefits to Quitting: how does the body recover?12 hours after quitting

The carbon monoxide level in your blood drops to normal2 weeks to 3 months after quitting

Your circulation improves and your lung function increases.1 to 9 months after quitting

Coughing and shortness of breath decrease; cilia (tiny hair-like structures that move mucus out of the lungs) start to regain normal

function in the lungs, increasing the ability to handle mucus, clean the lungs, and reduce the risk of infection.

1 year after quittingThe excess risk of coronary heart disease is half that of a continuing

smoker’s.5 years after quitting

Risk of cancer of the mouth, throat, esophagus, and bladder are cut in half. Cervical cancer risk falls to that of a non-smoker. Stroke risk

can fall to that of a non-smoker after 2-5 years.10 years after quitting

The risk of dying from lung cancer is about half that of a person who is still smoking. The risk of cancer of the larynx (voice box) and

pancreas decreases.15 years after quitting

How they work: How do E-cigs work?

•The user inhales through a mouthpiece.

•Air flow triggers a sensor that switches on a battery- powered heater.

•The heater vaporizes liquid nicotine in a small cartridge.

•The user gets a puff of hot vapor (containing chemicals to create the appearance of smoke) that feels a lot like tobacco smoke.

•When the user exhales, there is a cloud of vapor that looks like smoke. 7/25/2015

Good• Allows users to stop

inhaling the tar in regular cigarettes.

• Provides enhanced smoking sensation, allowing users to smoke less but feel the same effects.

• For smokers who want to quit, may help people quit through “nicotine free” or “light nicotine” options.

Bad• E-Cigs are currently

unregulated, meaning there is no law forcing manufacturers to disclose what other chemicals you are actually inhaling.

• Liquid nicotine is the most potent form of nicotine and can even be lethal if ingested.

• Young people are attempting to bypass the vapor and drink the liquid nicotine with deadly consequences.
