Former Warriors coach Don Nelson made his former players laugh back in February when he revealed how he was keeping busy in retirement.

"Yeah, I've been smoking some pot," Nelson told reporters in Oakland. "But! But I never smoked when I played or coached, so it's new to me. But anyway, I'm doing that, and I'm having a pretty good time. It's more legal now than it's ever been, so I'm enjoying that."

It turns out Nelson might have undersold his post-coaching habits.

In an interview that will air Tuesday at 10 p.m. ET during HBO's "Real Sports," he told Bryant Gumbel that he smokes marijuana every day and compared growing it -- and other plants -- on his Hawaii farm to raising a child.

"You've gotta treat it like a baby," Nelson said with a laugh. "You've gotta water 'em. You've gotta have music for them. You've gotta bless them when you go in. ... It's a whole process, I'm telling you!"

Nelson, 79, played 13 NBA seasons and coached for another 31. Last year, he told The New York Times that using marijuana medicinally helps him "deal with the pain without pain pills, and helps with that stress," revealing he began growing a self-named strain of marijuana called "Nellie Kush." Hawaii became the first state to legalize medical marijuana in 2000, expanding its program in 2016.
