The Food, Drug and Cosmetics Act defines dietary supplements as foods , and specifically, not drugs . GHB meets three separate provisions of the FDC Act that defines dietary supplements. It is, by federal legal standards, officially, a food . There are none. You might want to ask Mr. Pryor if Alabama has an analog-drug statute .
Most states do.
It is my considered opinion that there are no whole foods which do not contain detectable levels of several of these GHB-analog substances. Mr. Pryor's statement that GHB cannot be bought or sold in the US is entirely fictitious. GHB in food is openly sold. GHB-containing plastics are openly sold. GHB-containing clothing is openly sold.
