Some of the biggest findings in the subject of nicotine have come from the secretive Nicotine Research Collaborative, which is made up of researchers, doctors, and academics. However, because they were worried about political and professional issues, they never linked the organisation to any papers that were disclosed. Since the group has conducted extensive research on the nicotine molecule and reached contentious and frequently unpopular conclusions, its membership has remained unknown to this day. The group focuses on studying nicotine, not cigarettes or other tobacco products, and has never accepted support from the industry. An overview of their meetings over the past 30 years is provided in this booklet. As a student and later as a research associate of one of the most well-known thinkers and researchers in the group, I had the honour of attending these sessions.
