Should Fighters Be Tested Outside Competition?

This comes from Rick M via email.

More fighters test positive for recreational drugs than performance enhancing drugs. But still a low percentage for the actual amount of recreational drug usage that is involved in the sport. We've seen guys like Baroni and Randleman get busted, but the testing is random. It should mandatory for every fighter, at every event. It seems that recreational drugs - like coke, pot and others are very popular among fighters as well. The current state of affairs is simply too lax.
