Martina Pötschke-Langer, MD of German Cancer Research Center, Heidelberg, Germany talks about how doctors can address the issue of smoking. Doctors need to work together and focus on changing legislation. A possible approach which may be taken in Germany, is to ban advertising for tobacco products. Dr Pötschke-Langer thinks tobacco taxes are too low in most countries. Doctors must be aware of these issues in order to start initiatives.
