Passive smoking is dangerous than active smoking

Smoking is injurious to health but the one who smokes is not only getting affected by cancer, but he also spreads the disease to the one sitting nearby and inhaling that smoke. This is called passive smoking. An active smoker only inhales 20% of the smoke and lets off 80% in the air, those who inhale that smoke and get affected are called passive smokers. Though their intention was not to smoke they inhale some smoke let off by that smoker which leads to cancer. So smokers don’t smoke in a public place and infect others.
