It is known that the smoke from the tobacco users affects the surrounding people too. Secondhand smoke results in heart disease and lung cancer in non-smoking adults. Serious health conditions like sudden infant death syndrome, severe asthma and respiratory infections result in children because of the secondhand smoke. The Centers for Disease Control and Prevention (CDC) states that secondhand smoke is responsible for almost 50,000 deaths per year.
The National Institute on Drug Abuse (NIDA), a part of the National Institutes of Health conducted a study regarding the exposure of secondhand smoke. It revealed that the secondhand smoke creates cravings among smokers. It was also found that the secondhand smoke increases the vulnerability to tobacco addiction.
As per the study which used positron emission tomography (PET), it was demonstrated that exposure to secondhand smoke for one hour in an enclosed space results in enough nicotine to reach the brain. The nicotine from this secondhand smoke binds to the receptors which are generally targeted by direct exposure to tobacco smoke. This was found to happen in both smokers as well as non-smokers. According to a previous research, with exposure to secondhand smoke, children were more likely to become teenage smokers. The adult smokers also found it more difficult to quit smoking. It suggested that secondhand smoke has an impact on brain and promotes smoking behavior.
The study, therefore, resulted that moderate levels of secondhand smoke deliver nicotine to the brain and alters its functions. Higher brain nicotine levels result from the chronic or severe exposure and this explains that secondhand smoke exposure makes people vulnerable to tobacco addiction. This gives a strong evidence for banning smoking in public places, especially enclosed places and around children.
