David Crosby winds down his summer tour next week and took time out to talk about some of the more important aspects of life with The Las Vegas-Review Journal. When asked about what the 78-year-old, two time Rock and Roll Hall of Fame inductee regrets, Crosby said, "I used to do hard drugs. I would definitely tell my younger self to never do that again. They very nearly killed me. Just so much wasted time, but here I am. I'm the luckiest guy I know. I would also tell my younger self that only a few matter: the people and dogs you love, music, and my country."

Crosby, who remains and avid pot smoker and plans to start his own brand of pot, gave his thoughts on marijuana, explaining, "Weed is like beer and wine. It's mild. . . God knows we need the money for important things and I think legalizing it has the ripple effect. Plus, I had a conversation last night with two sheriffs from another state who said, 'I hope they legalize it here, so we can deal with real crime and not just bust kids for reefer.'"

Crosby spoke about his activism and lifelong fight for equality: "I've been fighting racism ever since I encountered Dr. King and black musicians. I've also been fighting for women. You're half the human race. You deserve half the power."

Ultimately with Crosby, it always comes back to music: "Music is a lifting force that makes things better. Just in the same way that war is a down force, music is the exact opposite. War brings out the very worst in the human race. Music brings out the best of our humility, compassion and love."

Among the many highlights on David Crosby's recent solo shows is the song "Radio," which Crosby, Stills, & Nash began performing back in 2012, with Crosby releasing it in 2015 on his critically acclaimed Croz album. Crosby says that he's amazed that the muse can still run so hot in him after decades of songwriting: "The thing that I like about 'Radio,' is that it's saying, 'You can reach out.' Not only can you, but it's your job to look out for other human beings. I'm encouraged by me writing a song like that when I'm this old, I'm this battered, and been through as much as I have. There's a youthfulness to it; a certain positiveness and I still believe!"
