Heather Mills refused to marry Sir Paul McCartney unless he stopped smoking cannabis.
The 37-year-old blonde said the former Beatle used the drug "as regularly as others drink cups of tea" and gave him an ultimatum to ditch his habit if he wanted to marry her.
She told Britain's Daily Mail newspaper: "Him and (his first wife) Linda smoked it every day for the whole of their lives together.
"But I would not get married to him if he was taking drugs. I hate it."
Heather also said she introduced the ban for the sake of their daughter, two-year-old Beatrice.
She added: "I could not have him lying to our child about not taking drugs and then going off for a sneaky puff.
"50 per cent of people can smoke joints their entire life and be fine. But the other 50 per cent, if there's a history of depression in their family or in their genes, they cannot smoke marijuana."
The former model, who lost a leg in a motorcycle crash, also revealed she has always been sober throughout her life.
She explained: "I've never taken drugs.
"I never really drank either until I met Paul. I was recently drunk on two glasses of wine at a Christmas party."
