From an article about the drug policies:
"Georgia, Kentucky and Mississippi State are the only ones with suspensions for athletes' first positive test for marijuana, 10 percent of the season for each. Kentucky includes possible dismissal for each of the first two positives, with a half-season suspension for No. 2.
The policy variations continue beyond the first positive test.
Six of the schools have a three-strikes-and-you're-out method. At Florida, you might get a fifth strike. At Arkansas, four. And Ole Miss doesn't have a defined number."
Apparently there are two standards, Drug tests by the school and those administrated by the NCAA. Also while it wasn't mentioned in this article Thug U's internal limit was five, per another article, and you have to wonder how many tests Thug U's FIVE STAR Jantzen failed before they sent him home for a spring semester to dry out. of course he didn't last any time at all when they allowed him back the fall semester. The player later charged with murder.
Note: UK's highest rated recruit and "most promising defensive player", Caffey, was kicked off the team PERMANENTLY after TWO positive tests.
