"If you look at rugby objectively, the sport needs strength, speed and endurance from its athletes, and that certainly fits the profile of those who might be tempted to use performance-enhancing drugs.
"Drug testing on the scale required would not be a cheap exercise and World Rugby, the world governing body, must take a lead.
"They must insist that richer unions allocate a substantial percentage of their turnover to finance a comprehensive independent testing programme, especially in the top-tier countries, including — and arguably most importantly — within schools.
"Along with betting, doping has the ability to totally undermine rugby, as many Olympic sports will testify."
Recent World Anti-Doping Authority figures for union and league showed were 66 failures from 2,673 tests in competition; compared to 54 failures from 4,693 out-of-competition tests.
"Rugby clearly has a drug problem, in both codes," the MoS reported.
"Of the 59 current UKAD sanctions, 17 are from union and 12 are from league at a time when the focus on size, speed and strength has never been greater."
Former England coach Dick Best said: 'If it's as little as 16 in-competition tests in 132 Premiership games it looks like a bit of a token gesture.
"And what worries me about that is the possibility that, as players become aware of it, they might be enticed to take more risks and do something stupid."
