oh yeah it happened to me about a week ago... i was hitting my bong and i was SO baked i forgot that i was holding the lighter over the weed for 20 secs and milking the bong. needless to say that was THE hottest smoke ive ever inhaled. i cleared the whole thing, fell down to the floor caughing, and almost passed out. my throat felt like shit for 2 days after, but i kept on smokin (i didnt milk it again for those 2 days because its just way too harsh to handle with a raw throat). oh and yeah that one single hit torched .5g bowl and kept me high for 3+ hours. it was kinda sweet, too bad i didnt enjoy it
