Music legend Willie Nelson is jumping into the movement to commercialize marijuana and plans to roll out his own brand of cannabis that he intends to make "the best on the market."

The singer-songwriter announced in a statement Monday that Willie's Reserve will be grown and sold in Colorado and Washington, two states where recreational use of the drug is legal.

A release explaining Willie's Reserve says it reflects Nelson's appreciation for "the many varieties and range of the plant's qualities."

The release says the 81-year-old Nelson will collaborate with master growers to define standards for the strain.

Nelson is a longtime supporter of marijuana for personal use and has spoken of its benefits for hemp production.

He's also pushed for the end of laws criminalizing use of the drug.
