If you manage to utilize cannabis to enhance your life, hats off to you. We can all admit to pursuing that, regardless of the substance of choice (mine being coffee and occasionally, nicotine). That being said, while cannabis use is more or less one of the safer addictions a person can develop, I think it is important to note its potential as a 'reverse gateway' drug. It normalizes smoking and has been found to increase the risk of future nicotine dependency in young adults who had not been exposed to either beforehand. https://www.ncbi.nlm.nih.gov/pubmed/16185213 Contradictory to this, some people claim that cannabis has helped them quit nicotine by providing a somewhat safer alternative. The studies investigating this are mostly looking into the motives for smoking cigarettes and pot. A friend of mine has been smoking cigarettes for over a decade and has been slowly replacing the tobacco with weed, now only smoking joints rather than spliffs.
