well im guessing
but
i think its becuase your 15.
your thinking the nicotine in a blunt is a buzz maybe
cuase i will tell you str8
the half a jiont, does u more than that blunt ,,,the blunt is just weed in a cigar wrap
now really think about it,i think maybe
you feel the weed faster in a jiont,why,becuase its not diluted with cigar wrap your smoking so when you toke a blunt,its not a real weed buzz your enjoying but a mix of the too,weed(thc) and cigs(nicotine)= blunt buzz,
i know people who cant smoke blunts,cuase they get sick on the nicotine

i get that way if i smoke too many cigs without eating ,or something
never off weed,
weed in fact settles my stomach down
next try just try half a jiont,,and stop
before ya get sick,
peace
