What are the best scientific and medical journal articles that provide solid evidence that vaporizing MJ is a healthier alternative to MJ combustion? When I look up the subject with typical keywords, I am overwhelmed with results and not sure who the most credible sources are. While I know it is ridiculous for anyone to take a stance against vaping, but being that it is still a federally illegal substance I did not know if there is any scientific and medical sources that I could present to the world's greatest skeptic. He specifically argues that MJ consumption is consumption; be it by vape or by fire [and soot]. ...I argue he is a numbskull and not worth the effort. But that numbskull is a relative so I figured I would take the higher ground () and educate with a few well regarded sources. Thanks!
