Mexican

Until around 1975, the great bulk of marijuana purchased in the United States was grown in Mexico. Recently, Colombian grass has become more popular. It tends to be stronger, for one thing, and it is also grown with less interference from the authorities Mexican growers often harvest their crops too early, to avoid detection, and this results in a steep decline in quality. In addition, Mexican marijuana has traditionally suffered from improper methods of curing and transport. Finally, the widespread use of Paraquat, a chemical defoliant, in the Mexican marijuana fields during 1978 made the Mexican product both scarce and unpopular in the United States.[9]
    "I find that certain high-altitude Mexican gives you a nice transparent high," says Lenny. "It makes you feel like you're walking around in a block of Plexiglas, and you don't feel sleepy." A clear, uplifting high is the most common designation of the better Mexican varieties, especially Oaxacan; it is usually green, with a smooth, spicy, and minty taste. It enters the lungs with a minimum of discomfort.
    Marijuana from Guerrero is also well regarded, but relatively few entrepreneurs are willing to venture into this wild and violent province. Even more scarce is the legendary Acapulco Gold. When it first appeared in the United States around 1964, it was one of the few quality varieties around; as a result, the name became popular and was soon being used to describe almost any good Mexican marijuana.
    Other Mexican varieties include the rare Zacatecas Purple ("only a handful of people in the whole country have tried it," boasted a California dealer); Popo Oro, which has a bluish tinge; Culiacan, grown in intense sunlight at high altitudes; Michoacan, which is silvery-light, pastel green in color, and very potent; and, in descending order of quality, Guadalajara Green (little more than respectable), Sinaloan (unimpressive), and finally a variety known as "Culiacan Garbage," which is apparently so disappointing that, according to Jerry Kamstra, author of Weed (a book about marijuana smuggling), "some dudes have even smuggled it back into Mexico so they won't have to look at it."
    In general, Mexican varieties are described as being happier and more mind-expanding than their Colombian counterparts. True, Colombian marijuana tends to be higher in THC; but the Mexican varieties, according to R., still have much to recommend them:

When people started switching to Colombian varieties in the early Seventies because of their "strength," as compared to Mexican, they were losing something, because some Colombians are unexcelled for inspiring contemplative philosophical states of mind, and some are amazing for the emotional and sensual intensities they evoke, but there's nothing like good old Mexican for laughter and sociability.
    In fact, it's unfortunate that more people don't start out smoking Mexican dope these days. People who have missed Mexican and started off smoking heavy Colombian often have their cannabis sensitivity stunned into a stupor by the sudden strength of some Colombian varieties. But to start by smoking Mexican, one gets introduced to many subtle initial levels of a high, subtleties that can be obscured in big bong blasts of Lumbo. Mexican has a delicate up-tempo, mariachi-like rhythmic complexity that few "heavier" dopes can duplicate.[10]
