Yesterday, Playboy Founder and longtime Editor-in-Chief Hugh Hefner passed away at 91-years-old. Besides creating Playboy, Hefner was also known for his support of a number of progressive causes including civil rights, gay rights and free speech. But another cause he supported has gone somewhat unnoticed: marijuana legalization.

In 1970, Hefner wrote a $5,000 check to help start the National Organization for the Reform of Marijuana Laws (NORML). He also contributed money to the organization and similar causes throughout his life. NORML still exists today and continues to fight for marijuana legalization. It's possible without a little help from Hefner, they wouldn't be around at all.

Here's a video produced by NORML telling the story about how Hefner got involved in their organization: 

The only way living in the Playboy Mansion surrounded by Playmates could've gotten any better is if he had easy access to legal marijuana.
