E-cigarettes come in various flavors that one can choose from; but the question is, which flavor is the most harmful among the rest of the choices?

As per Daily Mail, a recent study suggested that cherry flavored vapes are more harmful to one's health than other varieties.

Cherry flavored e-cigarettes contain higher doses of benzaldehyde, which can potentially irritate the lungs faster than other flavored products.

Benzaldehyde is safe for consumption as it is present in most food products; it is however hazardous once it passes through the respiratory system. Several studies were able to prove that benzaldehyde causes respiratory issues once inhaled.

The researchers performed a test on 145 e-cigarette flavors which included flavors such as berry, chocolate, tobacco, candy, coffee, tea, menthol and cherry.

The team gaged the benzaldehyde content of each flavor by creating aerosol vapors with automatic smoking simulator which tested 30 puffs per flavor.

After testing each flavor, they calculated the benzaldehyde content for 163 puffs which revealed that the cherry flavored vapes contained around 43 percent more benzaldehyde compared to other flavors.

The Material Safety Data Sheet for benzaldehyde highlighted the possible health risks of the chemical substance once it is inhaled: "Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. Serious Inhalation: Not available."

The date sheet which can be found on the Science Lab website pointed out that benzaldehyde is "Very hazardous in case of ingestion. Hazardous in case of skin contact (irritant), of eye contact (irritant), of inhalation. Slightly hazardous in case of skin contact (permeator)."

The researchers published their study in the journal "Thorax" wherein the conclusion mentioned, "Although e-cigarettes may be a promising harm reduction tool for smokers, the findings indicate using these products could result in repeated inhalation of benzaldehyde, with long-term users risking regular exposure to the substance."

Another study was also published in Tech Times wherein Temperance Rowell, the lead author of the study from the University of Carolina, stated that exposure to certain vape flavors can potentially cause cell damage due to the fact that some flavors are not yet tested and regulated by FDA.

Rowel told the reporters that "The outcomes seem to be very flavor-specific. Some of the chemical flavorings that are used are FDA approved, but that's more for ingestion than inhalation. Over the course of the 24 hour exposure, cell proliferation decreased greatly in adose-dependent manner."
