Top best answers to the question «Is 2nd hand smoke worse than smoking»
Firsthand smoking and secondhand smoke both cause serious health effects. While directly smoking is worse, the two have similar adverse health effects. Secondhand smoke is also called: side-stream smoke.
Side-stream smoke is more toxic than mainstream smoke, as it has much higher concentrations of cancer-causing substances. There is no safe level of exposure to secondhand smoke. Just 30 minutes of exposure to secondhand smoke can cause heart damage similar to that of an everyday smoker.
