While the point of the story is that the SEC is lenient on enforcement of marijuana use, there are some good tidbits in the article that show that some programs are far more strict. I'm not trying to stir the pot here, but it was a "hot debate" as to whether Marylands drug policy was too strict when it was announced that Parker and Stoglin were to be suspended for a year. While no specific mention was made as to the reason why, it was all but confirmed that it was due to multiple failed drug tests (3rd failed).

Since this is the first report that has come out recently that specifically documents the drug policies at the schools in a major conference, I figured that I would compare what the "3rd offense" does. I'll list them out below:

Florida: Suspended for 20% of the season. They have the most lenient policy out of all schools in the SEC. It takes five failed tests before you are suspended for a year.

Alabama: Same as MD, suspended for an entire year.

Georgia, Kentucky and Mississippi State: It does not detail the 3rd suspension, but they suspend 10% of games for the first positive test. Kentucky suspends half the season for the 2nd positive test with the possibility of dismissal.

In general: Six schools have a 3 strikes and you're out policy, which aligns with Marylands. So in summary, it appears that MD doesn't over punish at all, but they appear to be in line with at least half of the SEC.
