Environmental tobacco smoking is dangerous to both humans and animals as it contains cancer causing compounds. Nicotine found in tobacco affects the nervous system of both cats and dogs. It is therefore important to stop/reduce tobacco smoking in our environment to ensure better health for ourselves and our pets. This ONE HEALTH event is aimed at bringing together various disciplines from Human medicine, Veterinary medicine, and Environmental practitioners to increase awareness about the dangers of smoking on the health of humans and animals among students of Nottingham Trent University.
