Well, I used to make my music when I got back from doin the parties, so I was normally chemically enhanced.
I used to argue that the music was made for people in that state, so it would come across better.
Then I gave everything up, and also came to the conclusion that, If you can make your music give you a rush when you are straight. then anyone on chemicals is gonna feel it even more.

So I write most of my stuff when straight.

BUT drugs have taught me how sound can work on the brain at high volume.
