“Around 2005, I took all the pills out of the work. I still have the [pot] leaves, because I really like the shape of nature. I started growing and putting pot into my work, because I wanted some signifiers for the drug subculture other than geometric drugs that came out of the corporate-industrial complex. I thought it was all about the same thing, about altering your consciousness, or feeling better, or the lack of pain.”
