i got you all beat for stupidest thing smoked... during the winter of 5th grade me and this kid rolled tissues into regular paper and tried smoking them in the woods... we didnt know how to inhale yet so basically just sucked them in a blew it out... i dunno what we were thinking. did the same with dead leaves more then once to. sniffed all kinds of food things... one of the worst was wheat germ cause the particles didnt feel like they left my nasal caity for hours. kids are stupid.
I've actually tried smoking dead leaves, but that can actually get you high...just depends what plant they fell off.
