The hyperemesis described is not an acute OD-like effect, but happens to some chronic users. It wanes when cannabis use ceases. Very hot baths and showers help suppressing the nausea.
Like i said in another post, where I linked the pubmed reference, the most effective way to suppress that nausea is to apply capsaicin cream on the abdomen but like you implied the only way to completely suppress it is abstinence.
With that in mind, in any case - I can still not understand the logic of associating this phenomenon with "teens getting sick".
Also, if you cannot handle smoking weed chronically, maybe you should just stop. Personal responsibility again..

For whatever it's worth, that is also applicable to acute overdose.
