"Regulate" came from the soundtrack to the movie "Above The Rim" that starred 2Pac and Leon. It kicked off what Warren G. and Nate Dogg called the "G-Funk Era" for hip hop.
Nate Dogg passed away on March 15th, 2011 from complications from a stroke. His real name was Nathaniel Dwayne Hale.
Warren G. aka Warren Griffin III is working independently and kicked off his web site of the same name in April of this year.
Warren hooked up with Chris Kanik to promote a new natural male enhancement supplement called Affirm XL.
Hope they "Regulate" their usage and use it in moderation.-DocFB
