When I was in high school - Music and Art, in New York in the many decades ago... I noticed that there was a lot of creativity going on in the heads of guys who smoked alot of weed, and very little of it found its way onto the canvas. There were exeptions, but, art seems to happen when there is some irritation to scratch, when every thing is cool... why get up and paint, sing etc, and if you look at great times of artistic expression, it is generally a generation challenged to greatness, not a fat and comfortable generation. But, as I say this, one of my favorite contempory painters, who lived accross the hall from me in the 70s, to quote an old lawyer friend, was never known to draw a sober breath, and one could get a contact high standing outside his door.
I - myself, dont have the money or engery to get high. Too much else to do first.
