World heavyweight title contender Tyson Fury believes boxing has "a big problem with drugs" ahead of his fight with Wladimir Klitschko this weekend.
Englishman Fury, known for his outspoken views as well as his talent in the ring, feels his sport has a major issue with doping.
But the 27-year-old would not be averse to fighters being allowed to use drugs as he prepares to do battle with champion Klitschko in Dusseldorf on Saturday.
"I can look at a man and tell you if he's full of drugs by one glance at his body with his top off," he told BBC Radio 5 live,
"Boxing has got a big problem with drugs, but it doesn't bother me because at the end of the day it's about determination over drugs."
Fury added: "I think being in a democratic world means we have to be open to different things. Why don't they make drugs totally legal in sports and then it would be fully fair?
"If the governing bodies want to do that, it will be a bit fairer. You can't tell me that 99 per cent of these sportspeople ain't taking drugs if they've got bodies like Greek gods.
"If a man wants to pump himself full of drugs it's only shortening his life isn't it? When you're pumping yourself full of drugs it's putting pressure on your heart, your liver, your lungs, your kidneys.
"You're on a one-way ticket to a heart attack so that's why you see a lot of these bodybuilders and weightlifters having heart attacks young because they're pumped up so much and the heart can't take the pressure."
