The thing you have to understand is that a making film is a very complicated task. Your crew and cast is a machine, and like most other machines, should not be operated by someone under the influence. By being on mind-altering substances, the result is usually that you will have distracted your focus and the quality of your film will go down, you won't make your point and it'll just be "some asshole films himself high again"...
I actually told some of my actors on my latest feature that even though there's a lot of references to drugs (marijuana and psilocybin particularly) in the movie, I wanted everyone sober when we were shooting, so not to get any ideas, LOL. Particularly the actors. When you're high on marijuana, there are two emotions you can experience well- Shock/Awe and Fascinated/Happy. When you're sober, you can experience and tap into the full range of emotions and still stay focused technically. If you film an actor high when he's playing a character that is high, internally he'll probably be in a good creative zone, but will most likely forget lines, play it monotone, dull, and not be able to portray his internal emotions physically. But that same actor could have just, you know, ACTED high, and with more of a fine-tuned thought process you'd get a more interesting performance, a better shoot ratio and a less frustrated boom guy, AD, etc.
I think mind altering substances are interesting creative catalysts for writers- most of the renowned novelists of history and our time wrote their greatest work while under the influence of something, whether it be opium, psychedelics, buckets of ale, boxed wine or cat piss. I bet Shakespeare was sniffing horse shoe glue when he wrote Titus. The point is, they had the chance to sober up, come back to their work the next day and edit their insanity, enhancing the coherence and quality of their work. You can't do that on a film set!
So my point would be (and for legal purposes I am not suggesting you do this, but) if you want to experiment with psychedelics in a film, do the psychedelics to inspire you (like a method actor such as Nick Nolte would) and bring the MEMORY of that experience into your sober, thought-out, planned re-enactment for your video.
