The 26-year-old has been open about her use of the drug in the past, even declaring her love for cannabis as she lit a cigarette onstage in the Netherlands in September 2012, reported Contactmusic.
However, Gaga chose to shun marijuana as she worked on her upcoming release.
In an online chat she said, "No weed on Artpop. No. Weed in the bathtub though. Hahaha."
The singer also told fans to expect edgy music on her new record, adding, "Artpop is very risky. If you're not taking a risk you're not breaking any boundaries."
