Musician, who has been sober for 34 years, says marijuana is addictive and ‘leads to other drugs’

Elton John has hit out at the legalisation of marijuana in parts of North America, saying it was “one of the greatest mistakes of all time”.

The musician, who brought his touring career to an end last year and has been sober for 34 years, has helped fellow celebrities including Eminem and Robbie Williams to recover from addiction.
