Most of the tea leaves released after burning are carbon monoxide and inhalable particles. In addition, tar will be produced after combustion, which is harmful to human body. That is to say, in the case of burning, these healthy functional active substances contained in tea will be burned and turned into smoke, so the harm of tea smoke is also great.
At first, tea cigarettes were called "healthy cigarettes" under the slogan of quitting smoking instead of cigarettes, and were sought after by consumers. But later, it was found that the harm of tea smoke was actually the same as that of ordinary cigarettes, and tea smoke gradually disappeared from people's sight.
