A tobacco-like substance produced by drying the leaves and flowering tops of the cannabis plant, marijuana varies significantly in its potency, depending on the source and selection of plant materials used. The form of marijuana known as sinsemilla (Spanish, sin semilla: without seed), derived from the unplanted female cannabis plant, is preferred for its high THC content. .
             Marijuana is usually smoked in the form of loosely rolled cigarettes called "joints" or hollowed out commercial cigars called "blunts." Joints and blunts are sometimes laced with a number of adulterants including phencyclidine (PCP), substantially altering the effects and toxicity of these products. Street names for marijuana include pot, grass, weed, Mary Jane, Acapulco Gold, and reefer. .
             Although marijuana grown in the U.S. was once considered inferior because of a low concentration of THC, advancements in plant selection and cultivation have resulted in highly potent domestic marijuana. In 1974, the average THC content of illicit marijuana was less than 1 percent; in early 1994, potency averaged 5 percent. The THC of today's sinsemilla ranges up to 17 percent. As of August 2001, THC content in Marijuana produced in the Vancouver BC area averages in the 18 to 24 percent. On one occasion the THC content was measured at 36%, but that was a rare occurrence. "BC Bud" as it is referred, is in such demand that it sells for approximately $3000.00 per pound in the Vancouver area, $5000.00 per pound in Los Angeles and $8000.00 per pound in New York. .
             Marijuana contains known toxins and cancer-causing chemicals, which are stored in fat cells for as long as several months. Marijuana users experience the same health problems as tobacco smokers, such as bronchitis, emphysema and bronchial asthma. Some of the effects of marijuana use also include an increased heart rate, dryness of the mouth, reddening if the eyes, impaired motor skills and concentration, and frequent hunger and an increased desire for sweets.
