Researchers do studies and put out articles about what is healthy and unhealthy more often than I change undershirts. One day cholesterol is all bad, the next day there is a good kind too. One day cell phones cause cancer, the next day they don’t. I do not buy any of these studies, any except one that is. Smoking really does cause cancer, this is not a study, this is a fact and a logical one, filling your lungs and other’s lungs with smoke will obviously have consequences. Smoking should be outlawed completely, it will only benefit us.
