Average Thc Content Of Illicit Marijuana example essay topic

Marijuana (Cannabis) Cannabis sativa, the hemp plant, grows wild throughout most of the tropic and temperate regions of the world. Prior to the advent of synthetic fibers, the cannabis plant was cultivated for the tough fiber of its stem. In the United Stated, cannabis is legitimately grown only for scientific research. In fact, since 1980, the United States has been the only country where cannabis is licitly cultivated for scientific research. Cannabis contains chemicals called cannabinoids that are unique to the cannabis plant. Among the cannabinoids synthesized by the plant are: cannabin ol, cannabidiol, cannabinolidic acids, cannabigerol, cannabichromene, and several isomers of tetrahydrocannabinol.

One of these, delta-9-tetrahydrocannabinol (THC), is believed to be responsible for most of the characteristic psychoactive effects of cannabis. Research has resulted in development and marketing of dronabinol (Marino), a product containing synthetic THC, for the control of nausea and vomiting caused by chemotherapeutic agents used in the treatment of cancer, and to stimulate appetite in AIDS patients. Cannabis products are usually smoked. Their effects are felt within minutes, reach their peak in 10 to 30 minutes, and may linger for two or three hours. The effects experienced often depend upon the experience and expectations of the individual user as well as the activity of the drug itself. Low doses tend to induce a sense of well-being and a dreamy state of relaxation, which may be accompanied by a more vivid sense of sight, smell, taste, and hearing as well as by subtle alterations in thought formation and expression.

This state of intoxication may not be noticeable to an observer. However, driving, occupational or household accidents may result from a distortion of time and space relationships and impaired coordination. Stronger doses intensify reactions. The individual may experience shift in sensory imagery, rapidly fluctuating emotions, a flight of fragmentary thoughts with disturbed associations, and an altered sense of self-identity, impaired memory, and a dulling of attention despite an illusion of heightened insight. High doses may result in image distortion, a loss of personal identity, and fantasies and hallucinations. Three drugs that come from cannabis-marijuana, hashish, and hashish oil-are currently distributed on the U.S. illicit market.

These drugs have not currently been an accepted medical use in treatment in the United States. Today, cannabis is illicitly cultivated, both indoors and out, to maximize its THC content, thereby producing the greatest possible psychoactive effect. Marijuana is the most frequently used illicit drug in America today. The term marijuana, as commonly used, refers to the leaves and flowering tops of the cannabis plant. 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 sevilla: without seed), derived from the un pollinated 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 may be 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.

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. Extended use increases risk to the lungs and reproductive system, as well as suppression of the immune system. Occasionally hallucinations, fantasies and paranoia are reported. Hashish consists of the THC-rich resinous material of the cannabis plant, which is collected, dried, and then compressed into a variety of forms, such as balls, cakes, or cookie-like sheets.

Pieces are then broken off, placed in pipes and smoked. The Middle East, North Africa, and Pakistan / Afghanistan are the main sources of hashish. The THC content of hashish that reaches the United States, where demand is limited, averaged 6 percent in the 1990's. The term hash oil is used by illicit drug users and dealers but is a misnomer in suggesting any resemblance to hashish. Hash oil is produced by extracting the cannabinoids from plant material with a solvent. The color and odor of the resulting extract will vary, depending on the type of solvent used.

Current samples of hash oil, a viscous liquid ranging from amber to dark brown in color, average about 15 percent THC. In terms of its psychoactive effect, a drop or two of this liquid on a cigarette is equal to a single "joint" of marijuana.
