What is the difference between mainstream and sidestream smoke

Since the negative health effects of secondhand smoke have become more widely recognized, the percentage of non-smokers who are exposed to secondhand smoke has actually been on the decline since the early s. There are also fewer and fewer public spaces allowing smoking. In fact, many bars, restaurants, and some city streets have adopted completely smoke-free environments. While the risks of secondhand smoke for non-smokers are serious, smoking is still much riskier for those who chose to partake.

As such, here's hoping this information cleared the air around the risks associated with smoke exposure.

Originally Published:. The presence of smoke extracts enhanced platelet activity as compared to control conditions, this was especially prevalent for sidestream extracts.

With the addition of irreversibly glycated albumin, there was an additive effect, further enhancing platelet responses. The combination of cardiovascular risk factors can significantly enhance platelet activation and aggregation, and therefore it is possible to accelerate cardiovascular diseases through the interactions of multiple cardiovascular risk factors. Mainstream and sidestream smoke extracts caused increased platelet activation. Although low-tar mainstream extracts activated platelets less than high-tar extracts, the sidestream extracts were almost equally potent.

Modification of the filters of low-tar cigarettes, by blocking the air-bypass holes, raised activation rates by mainstream extracts to the level of high-tar extracts.
