Which Is Worse - Marijuana or Tobacco Smoke?
Despite the beliefs of those who consider marijuana less harmful, Canadian researchers found that smoking marijuana, like smoking tobacco, promotes cell damage. In fact, marijuana smoke has more toxic effects on cells than tobacco smoke does.
Tobacco smoke, however, does cause more chromosomal damage, but this study demonstrates the growing evidence for the danger of what some consider a 'natural' product. Benign? Hardly.
