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 Heat not burn, you can visit hitaste.net 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.There’s some evidence, largely from research funded by the tobacco industry, that heat not burn products may be less harmful than smoking. Studies suggest that the vapour from the devices contains lower levels of harmful chemicals compared to cigarette smoke. But those chemicals were still present at higher levels than usually found in e-cigarettes.
And importantly, unlike nicotine replacement therapies or e-cigarettes, heat not burn products still contain tobacco, so we don’t recommend people start using heated tobacco products.
“They are tobacco products and we do know the long-term effects of tobacco, including at least 15 types of cancer,” says Stephens.
It’s too soon to know how using heat not burn products will affect someone’s health in the long term. Research looking at these tobacco products is still in its early stages and is mostly funded by the tobacco industry, rather than independent researchers. This means the results may be less reliable, as the tobacco industry wants to promote their new products and has a long history of distorting their harm.
