Stormzy quits smoking ganja

Stormzy has stopped smoking marijuana in a bid to improve his mental health. The 26-year-old rap star has revealed he's decided to kick his unhealthy habit, admitting it used to make him feel "worse and worse and worse".

He shared: "If you've got mental health problems, stop smoking weed. It's not good for your mental health.

"I have suffered with mental health problems for the past few years.

"When I used to feel depressed, I would lock myself away and smoke weed and I would just get worse and worse and worse. It does not help your situation. It will f*** you up," the Shut Up hitmaker said.

"It feels good for, like, 20 minutes and then after that ... we all know, us weed smokers, we know how it goes."

Stormzy is a big advocate of maintaining physical fitness, too.

He said: "Exercise is good for mental health and also purpose. That's why I go back to that.

"Boxing - I feel like it's the greatest example because it gives you so much discipline and you've gotta learn, you've gotta stay sharp, you've gotta work at it every day to get better ... you have to stay focused."
