Houston Astros prospect Jonathan Singleton has been suspended for 50 games after having tested positive for marijuana.

Singleton came over to Houston from the Philadelphia Phillies as part of the Hunter Pence trade, and was ranked by Baseball America as the #34 prospect in baseball prior to the 2012 season.

Singleton wasn't likely to start the season with the Astros' major league club before the suspension, and now definitely won't.

It seems pretty dumb to me that testing positive for weed gets you the same suspension for testing positive for coke, PEDs, etc. Particularly when a player can get a DUI and not suffer any consequences. As more and more states legalize marijuana use, I suspect that we'll slowly but surely see MLB and other sports leagues adjust their drug policies to reflect the rather benign nature of that particular leaf.

But for now, Singleton will get to sit out the first two months of the season.
