Miley Cyrus -- Weed Can't Stop In Amsterdam

Stop us if this one sounds familiar ... Miley Cyrus was surrounded by weed last night -- only this time she was with super-sexy model Cara Delevingne.

Miley bounced from the Greenhouse in Amsterdam looking giggly and glassy-eyed after kicking it inside for a few hours with Cara and some friends.

The Greenhouse seems to be a popular spot for celebs ... with stoners like Snoop Dogg and Wiz Khalifa recently taking in the greenery at their shop.

Cara kept a low-profile when the group left ... but Miley was front and center looking awfully toasty.
