Michael Buble: I never wrote a song without marijuana
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.'
