It totally depends on what I'm smoking. When I first started smoking I never had the giggles really, then i quit for a little while and got them pretty bad for a month or two and now I don't really get them at all. If I get a really good nice high then I'll laugh at absolutely nothing sometimes, but the shit I have right now is really weird and gives me kind of a numb feeling so I don't really laugh, just kinda relaxed.
