Dhaka, Bangladesh - Provision of Designated Smoking Areas (DSAs) in hotels, restaurants, and trains has been ineffective, rendering non-smokers widely vulnerable to becoming victims of secondhand smoke, according to a study conducted on 118 residential hotels and 355 restaurants in Dhaka city, and 53 passenger trains. 

Among the 526 venues contacted successfully, only 41 or 8% venues had a DSA.

Those who vaped or smoked more frequently had higher DNA damage.

Epithelial cells line the mouth. DNA damage is an early change associated with an increased risk for cancer and inflammatory diseases.

“For the first time, we showed that the more vapers used e-cigarettes, and the longer they used them, the more DNA damage occurred in their oral cells,” said senior study author Ahmad Besaratinia. He is a professor of research population and public health sciences at the Keck School of Medicine in Los Angeles. READ MORE
