What is the Most Addictive Thing on Earth?

My answer was money.

For some reason I found the answer (below) intriguing. It just hadn't crossed my mind. Whether that's actually more addictive than heroin I'm not sure... it's hard to judge deaths from Becker's answer. Although they certainly exist and likely in great numbers. Note: I consider death to be a primary factor in determining the addictiveness of something.

Contest.

Here's the answer.
