Marijuana is a mixture of the crushed leaves and flowering tops of the hemp plant (Cannabis sativa). The plant contains a substance called THC (tetrahydrocannabinal) that has a combination of psychoactive properties which defy simple categorization. It produces euphoria and release from inhibition much like the depressant alcohol; the relaxation or even fatigue of a sedative; and hypnotic, sensory, and perceptual distortions like a mild hallucinogen (which ordinarily increases wakefulness). This is why marijuana and other cannabis drugs are treated as a unique category of psychoactive substance in the latest revision of the Diagnostic and Statistical Manual of Mental Disorders, or DSM III (1980). The various forms of cannabis   differ chiefly in their concentration of THC. Of the natural forms of cannabis, marijuana is the least potent, and hashish (pure plant resin) the most potent. Recently an almost pure form of THC has been artificially synthesized in the laboratory.

Cannabis is most frequently taken by smoking it in a cigarette or pipe. It can also be eaten (Alice B. Toklas, a friend of the poet Gertrude Stein, is said to have baked delicious marijuana brownies). At low dosages, most users quickly develop a feeling of relaxed euphoria. Some become more talkative, while others become quiet and contemplative. Many describe their perceptions and sensory experiences as intensified and unusual. Previously   unnoticed colors and sounds become vivid and important. Space and forms may appear distorted, and time slows. However, while many people feel only pleasant or interesting effects, others become anxious and irritable. The particular pattern of one’s reactions depends a great deal on the particular situation and the behavior of those who are nearby.

There are physical symptoms as well. The eyes redden as blood vessels dilate, the mouth dries as saliva flow is inhibited, and the heart beats faster; appetite often increases.

As more THC enters the bloodstream, the user feels more and more drowsy. Speech may become slurred and thinking distorted. Things may seem hysterically funny and inspire long spells of giggling. Finally, the user falls into a deep sleep.

For many centuries, cannabis was used in Asia as an anesthetic and medication for maladies ranging from insomnia to rheumatism. In the mid-nineteenth century, Western European doctors began to prescribe it for neuralgia, menstrual pain, and migraine headaches. In the early twentieth   century, its medical use was widely promoted in the United States by the drug company Parke-Davis. By the 1930s, however, doctors were prescribing such other drugs as morphine, aspirin, and barbiturates instead.
Marijuana began to be used simply for pleasure and was distributed illegally.

This period was marked by progressively harsher antidrug laws, and by 1937, marijuana, incongruously lumped with opium and heroin, was completely outlawed. During the 1960s marijuana use underwent a resurgence, with growing recognition that the harsh legal penalties seemed inconsistent with its apparent low level of danger, The National Survey of Drug Abuse (1979) reported that during 1979 more than 26 million Amercans icons used cannabis at least once, including 31 percent of adolescents under   18 (10 percent of all high-school seniors), 68 percent of individuals between 18 and 25, and 20 percent of those over 26. It is clear that earlier efforts to characterize cannabis as a “killer weed” were counterproductive exaggerations. Concerning its safety, however, real doubts still remain. Some evidence suggests that it is addictive.

Chronic users may develop tolerance (Nowland & Cohen, 1977) and experience  withdrawal symptoms such as loss of appetite, running nose, diarrhea, and sweating (Jones, 1977). Also, the potency of illegally obtained cannabis has increased, and there are more instances of accidents related to cannabis intoxication (Marijuana Research Findings, 1980). Longer-term dangers may include susceptibility to lung disease (Tashkin, Calvarese, & Simmons, 1978) and reduced fertility (Hembree, Nabias, & Huang, 1979).

There are many people in the world that believe weeds are only killed properly by noxious chemicals that pollute the air and possibly even the ground water in the area. Only these super potent death dealers can rid them of their weed problem. The truth is that some of the most effective killers of this unwanted plant life are entirely organic, biodegrade quickly, and destroy weeds fast.

The easiest natural weed killer to procure is actually nothing more than water. Yes, water kills weeds. This only fails to make sense until the rest of the concept is heard, however. The water must be boiling hot before it is applied. This quick, effective, method of killing these unwanted plants works very quick. The weeds will absorb the water into their system and the high temperature will destroy it from the inside out. This is similar to reasons why people are told not to water their outside plants and gardens during the hottest part of the day.

Beyond the source of all life known as water, there are other well known weed killers available. These range from highly acidic fruit juice, to vinegar. The type of juice and vinegar purchased directly from a store for consumption may not be potent enough, however. As a killer of plant life the best method will involve further distillation of store bought vinegar or lemon juice. These two items work because of the acetic acid they contain. Acids are one of the most common weed killing agents used. Other acids used are sulfuric, nitric, and pelargonic acids. These are found in grapes, apples, and carrots. The weed killer WOW! uses a formula derived from these types of plants, just as Burnout uses vinegar and lemon juice.

Natural killing agents for weeds come in many varieties. The best part is that using compounds made from primarily sulfuric or nitric acids will not only kill the weeds but also improve the ground soil. Sulfuric acid oxidizes with almost any mineral to create sulfates. These work well as a fertilizer aid for plants. A similar action occurs with nitric acids. This compound mixes with minerals to form nitrates, another important source of plant nutrition. Using organic chemicals such as this will destroy the weed problem and increase the health of the lawn altogether.

While many people will spend a great deal of money on noxious chemicals, the organic methods work well. They can also be self created and will improve the overall quality of the lawn in question when used.
