it sounds to me like you just took way too big of a hit, most ppl dont even get high their 1st time, so it was most likely just the large amount of smoke in you lungs

also a while back my friend also threw up from smoking, he just quit for a while and just recently started again...he just takes like 3 little hits then he stops smoking, he gets high from this and hasnt thrown up since, maybe you should try that, but deffinitely dont give up bro, keep on blazing! :rasta:
