Nah, went to hang out with someone IRL for the first time in a year or so. His friends smoked and all that shit in his house. I left after maybe 15 minutes, then came back later and sat around for 30 minutes.
Unless you were in an air tight room completely filled with smoke for like, an hour, you're good.
EDIT: I realize how much of an exaggeration this is now.
Here's to hoping you had more fun with it than I did.
Dude I LOVE it. It's really fun. But I can't wait til the Wii U version, apparently my state is gonna have a lot of tourneys around my area for Smash Wii U. Can't wait for it.
