I think it makes sense from many angles to test for performance enhancers like roids.
I doubt anyone would get kicked off tour for using them, but I'm not basing that on any real knowledge. Maybe guys already use them.
A lot of people seem to be scared they will test for weed. Do people consider weed performance enhancing? I've never heard anyone who smokes pot say anything but great things about it, so for someone who smokes to denounce it would be new. I have no idea cause I don't use.
I guess the main thing will be to legitimize the sport for the average person. If you have to use drugs to be a pro then what's the point? Nobody is asking free surfers to get tested. They already seem to do a good job keeping most of their drug problems private. Until it's too late. Though maybe that's another argument for testing.
