April 20, or 4/20, is known as "Weed Day" in some circles because the date corresponds with a numerical code for marijuana.

Yes, it seems arbitrary. So how did the number 420 come to represent smoking pot?

First, let's get the myths and rumors out of the way:

Some claim the number is drawn from the California criminal codes used to punish the use or distribution of marijuana. But the state's 420 code actually applies to obstructing entry on public land. So, not quite.

The rapper has been lighting up fans since his debut on Dr. Dre's aptly titled "The Chronic" in 1992. So it makes sense that he was one of the first to offer Twitter well wishes on 4/20 aka "Weed Day."

Snoop tweeted "4 m****f***in 20 #merryjane" bright and early Thursday. He also shared some imagery, including a headline about a plan by Bob Marley's son, Damian, to buy a former prison and transform it into a marijuana farm.

The singer has revealed she has smoked marijuana with her 20-year-old daughter, Bailey Jean, and 18-year-old son, Beckett.

"It was funny at first, and then they realized it's very natural [at the] end of the day," Etheridge recently told Yahoo. "It brings you closer. I'd much rather have a smoke with my grown kids than a drink."
