San Francisco-based graphic designer Brian Pollett has done what any physician would strongly advise you not to do - take a different narcotic every day for 20 days.
They weren't all class A's, though: he spent his last day high on love, which is probably just as well given the possible state of his mind, body and soul.
With the few brain cells he has left, he described the experience as something he'd wanted to do for years and that psychedelics have changed his core being.
It's hardly a surprising outcome, but at least he's answered the time-old question "I wonder what the artist was smoking when he did that".
Needless to say, the results are pretty trippy and watching the process even more so.
