All dice are doubled. No static modifiers are.
So a poison using +2d6 dice would double. Poison giving +5 damage will not.
Page 196 PHB: "When you score a critical hit, you get to roll extra dice for the attack's damage against the target."
Incorrect. Mike Mearls clarified this on his twitter account, even though there should be no need to. Poison damage is determined by the save, not the attack roll. It's not attack damage, it's save damage. Therefore, the damage dice is not doubled.
