New Study Reveals That Hookah Is More Toxic Than Other Forms of Smoking Tobacco

Smoking hookah may not be the best option to smoke tobacco, says a new study

While the popularity of hookah (tobacco pipe) has increased in recent years, researchers say it may be more dangerous than other forms of smoking tobacco.

Using a custom-built testing device, the researchers analysed emissions during a typical hookah session and found that one draw from a pipe contained as many noxious substances as a cigarette.

Hookah mainstream smoke, which is directly inhaled, has many toxic and harmful chemicals, like nicotine that can lead to tobacco addiction, irritating carbonyl compounds, and benzine, a known carcinogen,” said study lead author Veronique Perraud from University of California.

“Due to the greater volume inhaled in every puff and the longer duration of a smoking session, the hookah often delivers a higher dose of those chemicals to the smoker,” Perraud said.

It also produced large quantity of carbon monoxide, mainly from the burning of charcoal to heat the tobacco or herbal mixture in its bowl. The study, published in journal Aerosol Science and Technology, also referred to several cases of carbon monoxide intoxication.

In addition to testing ordinary tobacco, the group also studied a nicotine-free herbal mixture, marketed as a healthier alternative, and discovered that it produced even higher levels of toxic gases.

The study is the first to characterise ultra-fine particles (with a diameter smaller than 100 nanometers) in the inhaled smoke.

The researchers measured the chemical composition of gases and solids emitted during a hookah session in real time. “Through our technique of testing emissions in the beginning, midpoint and end of a smoking session, we were able to show that a smoker is exposed to a higher quantity of ultra-fine particles during the first 10 minutes compared with the rest of the session,” she said.

According to the study, these miniscule particles can pose significant health risks by making their way deep into the pulmonary system and by readily crossing the blood-brain barrier. (IANS)

Here’s How E-Cigarettes Can Be More Dangerous For Heart Health

Researchers have found that electronic nicotine delivery systems, such as E-Cigarettes might be just as harmful to the heart, than traditional cigarettes.

“Our results suggest that e-cigarette use is associated with coronary vascular dysfunction at rest, even in the absence of physiologic stress, these findings indicate the opposite of what e-cigarette and vaping marketing is saying about their safety profile,” said study researcher Susan Cheng, Director of Public Health Research at the Smidt Heart Institute.

A recent study by the US Food and Drug Administration found that 27.5 per cent of high school students used e-cigarettes in 2019, as compared to 20.8 per cent in 2018.

The study also estimates that in 2018, around 3.62 million middle and high school students were e-cigarette users.

For the current findings, the team of researchers compared healthy, young adult smokers aged 18 to 38 who were regular users of e-cigarettes or tobacco cigarettes.

The researchers then measured participants’ blood flow to the heart muscle – focusing on a measure of coronary vascular function – before and after sessions of either e-cigarette use or cigarette smoking, while participants were at rest and also after they performed a handgrip exercise which simulates physiologic stress.

It was also found that in smokers who had inhaled the traditional cigarettes, blood flow increased modestly and then decreased with subsequent stress.

However, in smokers who used e-cigarettes, blood flow decreased after both inhalation at rest and handgrip stress.

“We have known for decades that smoking increases your risk for heart attack and dying from heart disease, now, with this study, we have compelling evidence suggesting that newer methods of electronic nicotine delivery may be equally, or potentially more, harmful to your heart as traditional cigarettes,” said researcher Christine Albert.

Given that e-cigarettes represent a relatively new product in the market, Albert cautions users that there may be a number of unforeseen health effects.

To better understand the potentially dangerous consequences of e-cigarettes, investigators plan on studying the mechanisms underlying changes in heart and blood vessel flow seen in their work to-date, as well as the effects of e-cigarette use across a more diverse population of study participants including those with existing cardiovascular risk.

“What we are learning from our own research, along with the work of others, is that use of any electronic nicotine delivery system should be considered with a high degree of caution until more data can be gathered,” said study senior author Florian Rader.

The findings were presented at the annual American Heart Association Scientific Sessions 2019. (IANS)
