Although the two look very similar as young plants, their distinctions become very obvious as they mature. Hemp is tall and lanky with very few leaves and fewer branches; marijuana is much shorter and very bushy. Hemp matures much faster than marijuana (90 days versus 120 days). By the time farmers begin harvesting hemp, the pot would have just begun to develop its flowers, the only part of a marijuana plant that is of value for drug use. One of hemp's primary uses in cultivation is as a weed killer. Because hemp naturally grows much faster and taller than pot and because hemp plants are grown very close together -- 7- to 14-inch separation in row crops -- it creates a canopy over the pot, blocking the light and killing marijuana plant with all the other weeds. Even if the pot did reach maturity, its value as a drug crop would be greatly reduced because of cross-pollination. The hemp grown around the world today has as little as 0.03 percent THC; marijuana typically has 14 percent to 24 percent THC. The concentration of hemp pollen not only creates seeds, which decreases the quality of the flowers on its own, but also generates a lower THC marijuana plant on subsequent generations. T.D.
