Can you drill a hole in your skull to stay high?

Think of the brain as a pudding: It can expand and pulsate, but once the skull has completely sealed ’round it, it can no longer do that. The pulsation is suppressed and the blood passes through without pulsating. And this is why all of us want to get high.

What is the difference between lobotomy and trepanation?
