Smokers should be aware that their habit doesn’t only affect them, but also those they love and live with. Smokers produce second-hand smoke, via exhaled mainstream (active) smoke, as well as side-stream smoke from the cigarettes themselves. Non-smokers inhale this second-hand smoke, and this ‘passive smoking’ has harmful effects on the lungs and heart. If you’re a smoker, be careful not to smoke around your children and other non-smoking family members. Or better yet, ditch the horrible habit, and enjoy a longer, healthier life with your loved ones.
