Singer Michael Buble reckons pot makes him productive

Michael Bublé believes that marijuana has helped him writes hit tunes.

A Class B illegal drug in the UK, the drug can have a hallucinogenic effect.

Marijuana can be very useful in the studio,’ says Michael, 36.

‘I never wrote a song without a bit of a smoke.

‘It helps me create something good.’

But Michael admits model wife Luisana Lopilato, 24, doesn’t agree with him – and she made her feelings clear on a recent trip to Holland.

‘My wife hates the hash fumes,’ he tells The People.

‘Each time we passed a coffee shop I took a deep breath while she was disgusted.’
