Willie Nelson was in D.C. this week to play a Salute to the Troops benefit at the White House.

The country legend steered clear of perhaps his favorite topic — marijuana legalization — during the concert, but opened up to CNN following the show (via Rolling Stone).

Specifically, Nelson thinks that President Obama might want weed legalized.

"I think I realize how he feels about it," Nelson said. "And I've read some of his books and things about when he was a kid, how he maybe had delved into that matter a little bit. I'm sure he's very understanding of what's going on and he may be happy to see it happening."

The 81-year-old said money will be a driving factor.

"I think [it will happen] once people have realized ... how much money there is in it," he said. "Colorado and some of those other states have shown the people already that it's a very lucrative business. So I think it won't take long before the rest of the states come around."

Oh, and legalization might bring more peace and happiness to a turbulent nation.

"Well, I really think stress is the cause of a lot of our problems, and I really believe that the best medicine for stress is pot," Nelson said. "Yeah, I think it would make us get along better all over the world."

President Obama did not comment on Nelson's musical performance specifically, but noted the mix of artists (including Mary J. Blige, Common and John Fogerty) was appropriate, "because here in America, no matter where you're from, no matter what music you listen to, we're all united in our respect and admiration for our brave men and women who wear our country's uniform."

Nelson just signed a deal to host Inside Arlyn, a TV series that will feature guest performances and interviews inside Austin's Arlyn Studios.
