its only cheating if one purposefully kisses right at that time to get a taste of the chocolate.  if it happens on accident FOR REALZ then its not cheating.  i mean, spitting it out is somewhat offensive to the kissee right?  so just swallow but next time, let them know that its close to kissing someone after they’ve smoked…. just not as sweet as it could have been

No, it is not cheating, for me, I actually like chocolates, and I have experienced eating chocolates before I kiss my boyfriend. That was great, and yummy..

I would say yes, it does.  I’m vegetarian and don’t kiss my guy after he eats meat (until he considerately brushes his teeth). 
Meat is gross to me though, so it’s not a hardship to avoid it.  Sugar is still tempting, so it’s easy to look for ways to cheat…
