AFL players will be drug tested more than ever before as part of a raft of reforms to the competition's illicit drugs policy, to be outlined at Thursday's conference of the 18 clubs.
Clubs look certain to be granted the power to target-test players, but will have to pay for those tests.
AFL chief executive Andrew Demetriou has confirmed the game's working party into illegal drugs will present its report to the club bosses, having completed a series of meetings since it was established in January.
Under the proposed reforms:
■ Clubs will be granted the power to request increased general testing of its players, as well as target-testing of specific footballers;
■ Spreadsheets detailing player drug activity will be presented to all clubs as often as twice a year, with the players' names withheld although details of the illicit substances revealed;
■ The three-strikes policy will be upheld, with confidentiality remaining a cornerstone of the policy;
■ The AFL could establish more hair tests during players' holiday breaks, but the results will remain confidential and outside the three-strikes policy;
■ The self-reporting loophole will be removed, with players potentially restricted to one lifeline;
■ The AFL and the clubs will work to introduce increased medical and welfare resources and supervision specifically for players with mental health and/or addiction issues.
Demetriou refused to discuss details of the working group's proposed reforms, but said: ''I think it's fair to say our work has finished and the pillars of our illicit drugs policy remain.
''The proposed amendments will be put to the clubs and the AFL
Players Association and then to the Commission. [We are] confident the amendments will be supported.''
Despite a push by some clubs to introduce hair testing - which can trace illegal drug activity within the last two to three months - during the home-and-away season and finals, this relatively revolutionary procedure will not be permitted during the season or as part of the three-strikes policy.
The reforms look certain to be the subject of debate at the meeting of club chiefs, which will also include an address from AFL players' boss Matt Finnis.
While Finnis was initially at odds with Collingwood chief Gary Pert, a key contributor to the working party, the AFL, its players and clubs, along with medical officer Hugh Seward appear to be in general agreement over the proposed changes.
The drugs policy came under fire after the CEOs met late last year and Pert spoke of ''volcanic'' illicit drug activity presenting a significant risk to players and clubs during the players' holiday period.
The move by the players to lengthen their post-season break and not return to their clubs until December - a move strongly supported by Demetriou - has placed them on a collision course with some clubs pushing to at least postpone the extended holiday provisions until the end of 2014.
That too will be hotly debated at the club talks on Thursday.
The illicit drugs working party was established in January, with initial member Ian Robson removed after the Essendon supplements scandal was revealed. Ultimately, club chiefs Travis Auld (Gold Coast) and Stuart Fox (Hawthorn) joined Pert, Finnis and Demetriou to thrash out reforms.
The propensity for players to avoid a second or third strike by reporting themselves to the AFL doctors was identified as a key avoidance tactic.
It was also found the game needed to pour more resources into welfare and medical programs to ensure footballers suffering from depression and other health disorders did not fall victim to a dependence on illegal drugs.
While the players have demanded the three-strikes policy remain the cornerstone of the policy, along with assurances of strict individual confidentiality, the working party accepted that the illicit drugs crisis that erupted at West Coast in 2007 could have been better handled had the Eagles been given detailed knowledge of the drug strikes against its players, along with details of the substances involved.
