Remember when the industry insisted that e-cigs were better for you than cigarettes? They may have underestimated the risk of cardiovascular health.

There are two new studies published in the American Heart Association's peer-reviewed journal that looked into the effects of Vaping on cardiovascular health.

The effects of inhaling foreign substances instead of specific components of e-cigarette vapor or cigarette smoke were found in two studies.

Thousands of chemicals have been identified in tobacco smoke, some of which are also present in e-cigarette aerosols, either as an original ingredient or as a chemical reaction product of the heating process. We wanted to find out which component of smoke or e-cigarette vapor might be to blame for interfering with blood vessels.

Springer and his team exposed rats to traditional cigarette smoke and two types of gases associated with e-cigarettes. They were surprised that the gases and carbon particles had the same effect on tobacco smoke.

Both e-cigarettes and traditional cigarettes appeared to have the same effect on rats' blood vessels.

The second study found that both smoking and Vaping can cause changes to the heart.

One of the biggest implications of the study is that it makes it harder to regulate tobacco products. The act of inhaling stuff and not just specific ingredients within these products appear to be harmful if taken into legal consideration.

Springer said that it's important for regulators, clinicians and the public to know that Vaping is not harmless. Smoking and e-cigs can have the same harmful cardiovascular effects, but each can cause some potentially harmful effects that the other does not.

It was argued by the AHA that using both products together could be bad for one's health.

Bad news for boys! Vaping can be linked to male sexual problems.
