acapulco and columbian gold are NOT strains. they are called this the same reason that oil is refered to as black gold. they were the cash crop of that area of the world. they were however sativas, and many differant strains of sativa were refered to as gold.
alot of dealers back in the 70s would call there herb somthin just as a sales gimmik. with no idea where it actually came from.
