Herbal cigarettes are more harmful than normal cigarettes, finds study

Herbal cigarettes are more harmful than normal tobacco cigarettes, a study by IIT Gandhinagar has found. Herbal cigarettes emit 20% more sub-500 nanometre particles than normal cigarettes, which are linked to cardiovascular and respiratory diseases. "Our findings challenge the widely held belief that tobacco-free means risk-free," Assistant Professor Sameer Patel, of IIT Gandhinagar, said.
