Katy Perry says cannabis doesn't "agree with her".
The 'Dark Horse' hitmaker thinks she would turn into more of a "weirdo" if she smoked the drug.
Speaking recently whilst in Amsterdam for her Prismatic world tour, she said: "I'm going to go to the red light district tonight, actually, but I'll just say this: the weed doesn't agree with me.
"I turn into more of a weirdo than I actually am!"
The 30-year-old singer also insisted her partying days are long gone but she does enjoy a glass of wine now and then.
She added to Elvis Duran and the Morning Show: "I don't even really do cocktails anymore.
"There's a certain point in your life where you just turn to red wine, and that's kind of the point I've hit now. I love a nice Malbec."
Meanwhile, Katy recently admitted her body "can't take" as much drinking and says years of performing has had an effect on her physical health.
She said previously: "My knees are giving out on me now. I do acupuncture every two to three days. I tour with a sage that goes from the front of the house to the back of the house with a triangle thrust that is a moving treadmill, [like] I think I'm some kind of Olympic athlete!
"I don't drink much. I used to drink a lot more when I was younger. Body can't take it. Mind can't take it. Focus can't take it. You know how it is - 30, you just don't recover."
