tell your friend that there is no proof G-13 (probably the 'Govt strain' he's talking about) ever existed (maybe urban legend), and they didn't have the means to test THC accurately, in those days (60's), anyway ... besides, there are a handful of U.S. Govt' supplied patients that are still alive, who say the Gov't.-grown cannabis is very average-to-poor ... and, there's a lot more to pot, than THC ... :smokin:
