Adam Lambert lit up the joint earlier this week ... and then handed it to Miley Cyrus.
TMZ obtained this photo -- taken at Bootsy Bellows nightclub in West Hollywood -- showing a costumed Adam and Miley passing what sure appears to be a blunt.

In case you're wondering if the club tolerates it, as Simon Cowell would say, Welcome to Hollywood.
