New York, Aug 13: 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.

Bengaluru, Aug 19: Former Karnataka Chief Minister H D Kumaraswamy on Monday said he was not afraid of any probe into the phone tapping allegations, as he accused the BJP government of running a "transfer business" in the State.

The JDS leader's statement triggered a war of words with chief minister B Yeddiyurappa's son B Y Vijayendra saying it was not appropriate to make "baseless allegations."

Yediyurappa, however, said he was not going to react to the charges.

"Why do you want to put words in my mouth? May God bless him. The whole world knows what he has done..," he told reporters.

It all started with Kumaraswamy's purported statement on Sunday that Yediyurappa had left his sons to run the 'transfer businesses' as reported by some news channels.

Taking a serious note of it, Vijayendra tweeted the clipping of Kumaraswamy's statement as it appeared in a Kannada news channel, which read that Yediyurappa has "let his son loose to run the transfer business."

"...You cannot pass the buck on somebody else for your deeds. Stop trying to mislead the people through falsehood just because you are scared of the CBI probe into the telephone tapping case," he said.

Vijayendra also tweeted links to news reports that claimed the then PWD minister H D Revanna had transferred 700 officials on a single day last year when Kumaraswamy was the chief minister.

Later, speaking to reporters in Bengaluru, Vijayendra slammed Kumaraswamy for making "baseless allegations" against him and his family.

"It is not appropriate to make baseless allegations against me and our family. It does not befit his stature," Vijayendra said.

He challenged Kumaraswamy to make the facts public if he has evidence to back his claim.

"People have seen how during your tenure governance had collapsed due to the involvement of your family. People of the state have seen how 700 staff in the PWD were given promotion and transferred," Vijayendra said.

Reacting, Kumarasawmy cautioned chief minister Yediyurappa to keep his children "within their limits."

He alleged that the chief ministers residence has turned into a "transfer market" these days.

Speaking about the governments intention to conduct a CBI probe into the alleged phone tapping, Kumaraswamy said he was not scared of any probe because he did not do anything wrong.

However, he asked the chief minister not to fix innocent people only to take revenge on him.

Days after phone tapping allegations during the previous Congress-JDS coalition government surfaced, Yediyurappa on Sunday said he will order a CBI probe citing demands by several political leaders including from the Congress.
