Lady Gaga puffs on a giant spliff during a live gig as she tells fans about the “medical wonders” of ganja.
The American superstar, 26, was performing in Amsterdam, where smoking marijuana has effectively been decriminalised.
She told the audience she was in the “appropriate place” to discuss her passion for the drug.
She added: “I want you to know it has totally changed my life and I’ve really cut down on drinking. It has been a totally spiritual experience for me with my music.”
Gaga — who got through several outfits during the concert, including a leather number that revealed her backside — joked she was going to talk to President Barack Obama in a bid to make marijuana legal worldwide.
The Poker Face singer said the drug’s leaf symbol is the “new peace sign”. She added: “It’s like saying everybody needs to take a breath and it’s going to be OK.”
