psychoactive, those Cento certified are really good all by themselves. I have used many a can and you gotta taste the tomatoe before you add ANYTHING, cause they don't need nothin'. I generally take the tomatoe out of the can, leave the juice in the can. Hand crush the tomaoe to the desired consistancy. If too thick, add some of the juice from the can to get the consistancy you want. Be gentle with those or any fine foods.
