It can cause decreased immune function. Cancer, heart disease. Long term health issues. Your family can be at risk too from passive, second-hand smoke. Smoking puts those closest to you at risk.
The American heart association changed ABC (Airway, Breathing, Compressions) to CAB (Compressions, Airway, Breathing) because when the ABC sequence to perform CPR was performed, people would spend so much time trying to open the airway that there was a delay in chest compressions making rescue breathes harmful. With the new CAB sequence people initiate chest compressions sooner and ventilation is only slightly delayed.
