Auto grade nitrous oxide has sulfur dioxide which tastes and smells bad, presumably to prevent people from inhaling the automotive grade. I haven't vented much co2 gas, but have not noticed anything like that when I did. Its meant to be a noticeable additive (like the additive to natural gas, but not the same), but I'm not sure why it would be added to co2. Probably still lingering from when it was filled with the nitrous gas which does say it had so2 in it.
