Acapulco Gold is the traditional name of a legendary, dank potent strain of marijuana (Cannabis sativa L.) originating in Mexico. Like Panama Red, Acapulco Gold became popular in the cannabis-smoking underground during the 1960s and 1970s. Although it is increasingly rare, Acapulco Gold is still grown in more remote areas of its native range. The rise of Cocaine trafficking has brought the general decline of Cannabis culture in Mexico. Due to inbreeding much of the Acapulco Gold that is still grown has lost its potency. Some longtime U.S. growers maintain clones of heirloom plants purported to be Acapulco Gold. Many people saved seeds during the heyday and still today there are old Acapulco Gold seeds sitting in coffee cans in attics.
Some claim that the famous gold color of Acapulco Gold came from a technique of "girdling" the plants, or cutting through the xylem and phloem layers of the stalk, before harvest. This supposedly would cut off the flow of nutrients to the plant, leaving the stalks and buds a blanched golden color at harvest time. Many techniques such as this are used by traditional growers to shock or stress the plant during flowering, in the belief that the plants will respond to stress by producing more of the active (THC-containing) resins responsible for the plants' medicinal potency. This theory has been refuted by people who have grown Acapulco Gold outside of Mexico. The gold coloring is the natural coloring of this plant. More specifically, when grown under normal conditions, Acapulco Gold will cure with golden pistils and yellow to pale green leaves which makes for an overall golden appearance. This is the same with Santa Marta Colombian Gold.
It is also possible that the Apple of Discord was made out of Acapulco gold, as mentioned in the Principia Discordia.
