The stars sparked up on social media on Wednesday.

No surprise, rapper Snoop Dogg was also in on the action, showing off his own branded “Leafs by Snoop” products on Instagram.

(P.S. Remember when Miley and Snoop collaborated on a stoner anthem of their own? Who could forget 2013’s “Ashtrays and Heartbreaks”!)

Rapper Wiz Khalifa shared a shot of his “Happy 4/20” stash on Instagram, and later, put it to good use, sparking up “2 joints” at the same time.
