I just read this quote from Steve Jobs:

"Doing LSD was one of the two or three most important things I have done in my life."

Now I'm wondering:

• Has there ever been a study where programmers have been given drugs to see if they could produce "better" code?
• Is there a programming concept, which originated from people who where drug-users?
• Do you know of a piece of code, which was written by someone under the influence?

EDIT

So I did a little more research and it turns out Dennis R. Wier actually documented how he took LSD to wrap his head around a coding project:

"At one point in the project I could not get an overall viewpoint for the operation of the entire system. It really was too much for my brain to keep all the subtle aspects and processing nuances clear so I could get a processing and design overview. After struggling with this problem for a few weeks, I decided to use a little acid to see if it would enable a breakthrough, because otherwise, I would not be able to complete the project and be certain of a consistent overall design"[1]

There is also an interesting article on wired about Kevin Herbet, who used LSD to solve tough technical problems and chemist Kary Mullis even said "...that LSD had helped him develop the polymerase chain reaction that helps amplify specific DNA sequences." [2]
