Don't think it was a dope test, just part of his pre-fight physical.

However, it would make sense to test that blood if they are drawing it for that reason, surely they could draw a little bit more and test it.

I think a large part of the problem here is that Pac is so far away and in a country where the telecommunications system is pretty messed up. I have to occasionally call the Philippines for work and it's a nightmare getting through sometimes. Also, it's been Christmas so he's probably unwinding with family etc, but I sometimes wonder if he knows just how big a shit storm this is
