Remember that one of the by-products of the conversion of 1,4 into GHB is ethylene glycol. This substance is not readily removed from the body, and the possibility exists, it would seem to me, that an excess of 1,4 consumption would have much more serious consequences than that of similar GHB consumption. I have tried them both, of course, and 1,4 just SEEMS harmful for some reason. I cannot find any literature to back this up, however I do know of one individual who had his liver panel taken after some heavy 1,4 consumption through a summer, without any other drug use, and found his bilirubin to be at 2.9! That is high, folks.
