There was also Mexico Gold. The summer after my freshman year ('71) I bought a pack of "cigarettes" from a high school bud whose brother had sent a carton from Nam. The story was that the filters were laced with opium. All I know is that it was some crazy sh¡t. I have a number of classmates (both high school and ND), many I see to this day, who will attest to its potency .
Sad to say, this was the time that weed, LSD, Peyote, Mescaline, Peyote, etc. were in transition from a social to a business enterprise. I miss the old days.
