I share some concerns with the commenters on the article. Having used salvia a few times, I can confirm that the way in which it is smoked has a drastic effect on the outcome. I can't imagine that the variables (method of combustion and inhalation, temperature, quantity) can be reasonably controlled for by observing home videos.
I assumed it was more of an exploratory study to figure out the possible effects. What's really amazing though is that A) people are dumb enough to post videos of themselves doing this and B) we're now doing science by observing YouTube videos. The whole method is brilliant for what it is, just think of how hard it would have been to get FDA and IRB approval to do this study the traditional way.
