The theory of tobacco abstinence is currently being challenged by a new idea called (THR). THR splits tobacco into two parts: the harm caused by smoke and tar, and the harm caused by nicotine. Because nicotine addiction is the main problem when it comes to getting smokers to quit smoking, THR theory looks at the harm caused by nicotine itself compared to the harm caused by smoking. The good news is that nicotine is fairly safe in low doses, comparable to caffeine in effects and dangers. So in short, THR aims to give smokers who are unable to quit smoking an alternative source of nicotine to reduce tobacco harm.

The paper defends its ethical standards by arguing that it "was consistent with Facebook's Data Use Policy, to which all users agree prior to creating an account on Facebook, constituting informed consent for this research."

These studies are simply ignored by the Surgeon General's report and by my colleagues who have attacked me. It would be one thing if there were no evidence for my opinions, but it's hardly appropriate to attack an individual for expressing an opinion that is backed up by scientific studies.
