I have never smoked salvia or really knew of anyone smoking it, but from what I can tell just a couple hits and you lose all your motor skills. First off, why would you place a video of you smoking salvia on a public domain? Secondly, it seems like most salvia users need to be in a padded room to stop from getting hurt.

This guy takes two hits from the bong and literally has a "bad trip" right out of a window. Let's watch him make a fool of himself.

This is the first part of the video, the second part is a bit long, but shows the dude didn't get hurt. Good for him, bad for his windows and blinds.
