The Truth about Smoking

The smoking has absolutely no benefits for you, but only one ''The Death'' if you wana die without any other effort to make a suicide.

Do not smoke and do not allow yourself to be exposed to smoke because second-hand smoke and third-hand smoke are just as deadly as first-hand smoke, say scientists who conducted the first animal study of the effects of third-hand smoke.

"We studied, on mice, the effects of third-hand smoke on several organ systems under conditions that simulated third-hand smoke exposure of humans," said Manuela Martins-Green, a professor of cell biology who led the study. "We found significant damage occurs in the liver and lung. Wounds in these mice took longer to heal. Further, these mice displayed hyperactivity."

Study results appear in PLOS ONE.

The results of the study provide a basis for studies on the toxic effects of third-hand smoke in humans and serve to inform potential regulatory policies aimed at preventing involuntary exposure to third-hand smoke.

Third-hand smoke is a potential health threat to children, spouses of smokers and workers in environments where smoking is, or has been, allowed. Contamination of the homes of smokers by third-hand smoke is high, both on surfaces and in dust, including children's bedrooms. Re-emission of nicotine from contaminated indoor surfaces in these households can lead to nicotine exposure levels similar to that of smoking. Third-hand smoke, which contains strong carcinogens, has been found to persist in houses, apartments and hotel rooms after smokers move out.

The team led by Martins-Green found that the mice exposed to third-hand smoke in the lab showed alterations in multiple organ systems and excreted levels of a tobacco-specific carcinogen similar to those found in children exposed to second-hand smoke (and consequently to third-hand smoke):

In the liver, third-hand smoke was found to increase lipid levels and non-alcoholic fatty liver disease, a precursor to cirrhosis and cancer and a potential contributor to cardiovascular disease.

In the lungs, third-hand smoke was found to simulate excess collagen production and high levels of inflammatory cytokines (small proteins involved in cell signaling), suggesting propensity for fibrosis with implications for inflammation-induced diseases such as chronic obstructive pulmonary disease and asthma.

In wounded skin, healing in mice exposed to third-hand smoke showed many characteristics of the kind of poor healing observed in human smokers who have gone through surgery.

Finally, in behavioral tests the mice exposed to third-hand smoke showed hyperactivity.

"The latter data, combined with emerging associated behavioral problems in children exposed to second- and third-hand smoke suggests that with prolonged exposure, they may be at significant risk for developing more severe neurological disorders," Martins-Green said.

Although the potential risks attributed to third-hand smoke exposure are increasing, virtually nothing was known about the specific health implications of acute or cumulative exposure -- until now.

"There is a critical need for animal experiments to evaluate biological effects of exposure to third-hand smoke that will inform subsequent human epidemiological and clinical trials," Martins-Green said. "Such studies can determine potential human health risks, design of clinical trials and potentially can contribute to policies that lead to reduction in both exposure and disease."

Her research team was surprised to find that the damage caused by third-hand smoke extends to several organs in the body.

Quitting smoking: 10 ways to resist tobacco cravings;

Tobacco cravings can wear you down when you're trying to quit smoking or chewing tobacco. Delaying, avoiding triggers, yoga and nicotine replacement are among the ways to resist cravings.

1. Delay. If you feel like you're going to give in to your tobacco craving, tell yourself that you must first wait 10 more minutes and then do something to distract yourself for that period of time. This simple trick may be enough to derail your tobacco craving. Repeat as often as needed.

2. Don't have 'just one.' You might be tempted to have just one cigarette to satisfy a tobacco craving. But don't fool yourself into believing that you can stop at just one. More often than not, having just one leads to another, then another — and you may wind up using tobacco again.

3.Avoid triggers. Urges for tobacco are likely to be strongest in the situations where you smoked or chewed tobacco most often, such as at parties or bars, in the car or while watching television. Identify your trigger situations and have a plan in place so that you can avoid them entirely or get through them without using tobacco. Don't set yourself up for a smoking relapse. If you usually smoked while you talked on the phone, for instance, keep a pen and paper nearby to occupy yourself with doodling rather than smoking.

4. Get physical. Physical activity can help distract you from tobacco cravings and reduce the intensity of cravings. Just 30 minutes of moderate physical activity can make a tobacco craving go away. Get out for a walk or jog. If you're stuck at home or the office, try squats, deep knee bends, push-ups, running in place, or walking up and down a set of stairs a few times. If physical activity doesn't interest you, try prayer, needlework, woodwork or journaling. Or do chores for distraction, such as vacuuming or filing paperwork.

5. Practice relaxation techniques. In the past, smoking may have been your way to deal with stress. Trying to resist a tobacco craving can itself be stressful. Take the edge off stress by practicing relaxation techniques. These include deep-breathing exercises, muscle relaxation, yoga, visualization, hypnosis and massage.

6. Call reinforcements. Touch base with a family member, friend or support group member for moral support as you struggle to resist a tobacco craving. Chat on the phone, go for a walk together or simply share a few laughs — or get together to commiserate about your cravings.

7. Remember the benefits of quitting. Write down or say out loud the reasons you want to stop smoking and resist tobacco cravings. These might include feeling better, getting healthier, sparing your loved ones from secondhand smoke or saving money. And if you're a closet smoker, you may save hours of time since you no longer have to spend time trying to conceal your habit.

8. Go online. Join an online stop-smoking program. Or read a quitter's blog and post encouraging thoughts for someone else who might be struggling with tobacco cravings. Learn from how others have handled their tobacco cravings.

9. Try nicotine replacements. Try a nicotine replacement product instead of a cigarette. Some types of nicotine replacement therapy, including patches, gums and lozenges, are available over-the-counter. Nicotine nasal spray and the nicotine inhaler are available by prescription, as are the stop-smoking medications bupropion (Zyban) and varenicline (Chantix).

10. Chew on it. Give your mouth something to do to fight a tobacco craving. Chew on sugarless gum or hard candy. Or munch on raw carrots, celery, nuts or sunflower seeds — something crunchy and satisfying.

Remember, trying something to beat the urge is always better than doing nothing. And each time you resist a tobacco craving, you're one step closer to being totally tobacco-free.
