Did you even read the articles or just the abstract? Lol. No numbers no data no nothing and, just going from the abstract we have Estrogen article -only 1 form of thc they tested reacted with estrogen recepters at very concentrated levels[b]in rats[/b] and cpuld not be reproduced in vivo. Shrinks your brain article- no data or evidence but ok again going off the abstract it clearly says it only affected thoze smoking before 17 and it MAY have a link Carcinogen presence article- clearly states multiple studies showing any causual relationship is still needed Yes any fool can go on pubmed or google scholar, read an abstract, and suddenly be an expert on the subject
