5 common questions about 'heat not burn' products answered


'Heat not burn' or 'heated tobacco' products are electronic devices that, unlike e-cigarettes, contain tobacco leaf and heat it to a high temperature, without setting it alight.To get more news about HNB, you can visit hitaste official website.

This difference is important. Because the devices contain tobacco, they come with all the long-term health concerns of tobacco. And with the tobacco industry investing heavily in research, development and marketing of these new products, understanding what's in them is vital.

So how do they work? And are they safe? We caught up with Dr. Ed Stephens, a researcher at the University of St Andrews, whose work has compared the health impact of tobacco, e-cigarettes and heat not burn products, to find out more.Heated tobacco products work by using electricity to heat sticks of tobacco, producing a vapour that's inhaled. The vapour contains nicotine, chemicals and other tobacco particles that are also found in traditional tobacco smoke.

"I don't like the term heat not burn," says Stephens. "The word 'burn' has two meanings. The first is to light something so that it catches fire and continues to combust until the fuel runs out, like a candle or a cigarette. The second is to heat something until it chars around the edges – like when you leave a cake in the oven for too long and it chars. Switch the oven off and the charring stops. Heat not burn products don't burn like a cigarette, but the tobacco is 'cooked' and may even char. So it would be better called heat not combust."

The devices heat tobacco to 350C (662F), far lower than traditional cigarettes that burn at temperatures up to 900C (1,652F), but still high enough for harmful chemicals to be released into the vapour.
