For starters, no study was actually posted, just screenshots from alleged study. But I actually the found the video; this is old hat (and hardly scientific.)

When the author of the video that everyone is claiming is scientific says "this hasn't been done enough to be considered real science," well...
Everyone's favorite canna scientist Dr. Bruce Bugbee doesn't quite agree either:
Skip to 37:05. He's still basing his recommendation on principle of the science, but I think Bugbee has a little more credibility than one random video produced by PSI Labs.
