smokers get cancer, tobacco contains carcinogens, however, studies rarely take enough account of the wide range of conditions that contribute to health, stress, nutrition, socio-environmental conditions, mental health, exercise, meditation and mindfulness, these are often left out, clearly they have an effect, it's not an easy task, I'm not an advocate of ingesting harmful substances, I am an advocate of interdisciplinary research that helps us understand the why and how humans are susceptible to what seems like 'wrong choices', or are they, see 'The Paris Problem', problem eh... don't forget the man in the dark street searching for his lost keys only under the light from a streetlamp..
