Everybody Must Get Stoned!

So I read that the Rolling Stones are playing in Serbia and the usual drug haze that goes with those shows will be centered over the stables nearby...

BELGRADE - A plan to sedate more than 300 horses stabled at Belgrade's racecourse to keep them calm during a Rolling Stones concert there has enraged Serb animal lovers who are lobbying to have the gig moved to another venue.

The concert is expected to draw more than 100,000 people to the Hippodrome, Belgrade's largest fenced space. The horses will be only a few meters from the stage.

Actually, I think this sounds like a terrible thing to do to the horses. Why shoot them up with sedatives when the marijuana contact high will work just as well?
