Since the introduction of Marijuana to the American Public there has been an unresolved debate as to whether the said drug renders positive or negative effects on its users. This paper shall provide the arguments and evidences provided by each side; and shall opt to take the stand that marijuana is a harmful drug when used beyond its supposed medical capacity. I personally oppose any form of regulated substance that has been deemed as an addictive drug. If marijuana is being used merely for recreation or short term (often myth) benefits then there is no good reason for our government to loosen its laws prohibiting the use of cannabis.

On the other hand, it must be noted that there is enough scientific evidence regarding the medical value and potential marijuana has for ill persons. Let us first begin my laying down the research as to how marijuana affects ones brain and consequently other aspects of an individuals physiology and life. Marijuana (also termed as joint, hannabis (the species of plants that the drug is made from), weed, pot et cetera); is commonly taken into the body either by smoking or mixing it into foods and liquids.

The main chemical component that induces the high is the THC ((delta-9-tetrahydrocannabinol) which binds with the cannabinoid receptors in the brains nerve cell membranes (NIDA InfoFacts: Marijuana, 2006). The THC causes a chain of cellular reactions that leads to the brain and body to experience various symptoms taken to be the high sensations that marijuana users experiences (NIDA InfoFacts: Marijuana, 2006). In order for a more elaborated understanding of how the above mentioned proceeds, we shall trace the step by step manner of how marijuana enters the body and affects the brain.

When an individual takes a puff or smokes a cigarette type of marijuana the latter is immediately inhaled into the lungs. Consequently, the THC component and other toxins of the said drug is absorbed into the blood stream and travels to the different parts of the body including the brain (NIDA InfoFacts: Marijuana,2006). As already mentioned the THC merges with the cannabinoid receptors, the latter influence various sensations including pleasure, cognitive skills (i. e. memory) sensory and time perception, and kinesthetic coordinated function. This affects the functioning of an individuals brain both short term and long term.

Thus, when the brain experiences the effects of THC, the body would also manifest the symptoms of drug use. The result of marijuana in a persons system may cause him/her to use marijuana for a. ) Mood-altering properties and, b. ) Its proven medicinal applications. I believe that the latter is the only acceptable use of marijuana. Yes, the angling of ones consciousness may lead one to believe that the feel-good sensation of marijuana is harmless. However if we appeal to everyday psychology it is highly detrimental to a persons ability to live his/her full potentialities due the hallucinogenic effects of marijuana.

One becomes addicted and dependent on marijuana in the belief that such user would not be able to perform his or her tasks and moreover feel good about him/herself. From a psychological perspective this causes an individual to escape from reality and retards growth and development both socially and physiologically. The laughing state stimulated by marijuana is experienced with the sensation of hunger, hyper sensory sensitivity and inability to grasp ones surrounding as a whole. Marijuana is also seen as a trigger for a heart attack to those with pre-existing heart conditions.

Habitual use of the said substance would result to ones body becoming immune to its medicinal benefits. Since this drug contains toxins that are found in tobacco, and is ingested more directly and held in the lungs by marijuana smokers, there is increase chance of developing lung cancer. In terms of long term use, the psychological effect of marijuana is similar to drugs like heroine and cocaine in the sense that since the body becomes immune; an increase in dosage becomes necessary in order to induce the same effects of so-called euphoria.

Marijuana affects the portions of the brain designed to manage the sex and growth hormones of boys and men. As a result, male users may experience a decrease in their testosterone level and sperm count as well as the development of abnormal kinds of the latter. As such, one of the manifestations of low testosterone is the development of breast that has been reported to be due to the hormonal imbalance of male pot users. Further, marijuana is considered to be one of the contributing factors in the rising count of infertile males (Narconon: Effects of Marijuana, 2001).

On the other hand brain control of hormones is also affected in woman. As a result the latter would experience irregular menstrual cycles as a result of drug-use. Further, pregnant women who use marijuana often give birth to infants exhibiting symptoms of drug withdrawal and even fetal marijuana syndrome. As such these babies have high risk of having development and learning disabilities as well as hormonal irregularities (Narconon: Effects of Marijuana, 2001).

Scientific study has shown that THC directly affects the brain in very detrimental ways, as Narconon further reports: THC changes the way in which sensory information gets into and is acted on by the hippocampus that is crucial for learning, memory, and the integration of sensory experiences with emotions and motivations. Investigations have shown that neurons in the information processing system of the hippocampus and the activity of the nerve fibers are suppressed by THC. In addition, researchers have discovered that learned behaviors, which depend on the hippocampus, also deteriorate. (Narconon: Effects of Marijuana, 2001)

It is the case that marijuana when regulated and prescribed properly for ill persons could benefit from the said drug. There is economic as well as valid medical advantage derived from the prescriptions of marijuana and the latter is promising in terms of helping cancer patients as well as those inflicted with glaucoma. Further the government should maintain the crack down of drug users who apparently use marijuana without probable medical cause. In another perspective however, the government should loosen up the status of marijuana from a prohibited substance towards a regulated one.

The American public would be able to use Marijuana over pharmaceutical drugs offered over the counter. Surely, our government is far more concerned in being able to provide the best quality of health even if it means re-evaluating drugs it previously judged as illegal. The brain is a highly complex system, marijuana and its symptoms could aid in allowing better function for those sick individuals in need of appetite stimulants and natural pain relievers. However, the public ought to be warned that the abuse of marijuana when one garners to medical benefits from its use is subject to future complications.

Yes, marijuana is organic, but like everything else, when abused and misguided in its use it could be harmful to ones body. Sooner or later when one becomes a habitual if not chronic user of marijuana the latter would eventually fry the persons brain. Normal function is difficult to regain once the THC becomes a regular visitor to ones nerve cells. Marijuana debilitates an individual to exercise his or her full cognitive capacity as a result there is huge correlation between academic failure and pot use. The above mentioned also produces a lethargic sensation making it difficult to go through the day.

It is the case that recent study show that the effects and the substances in marijuana stays in ones brain even after one seizes to smoke a joint (Warner, 2005). As a result the disadvantages of the said drug are manifested further through long-term observation. One may be able to survive the short term effect but what is disturbing is the fact that sooner or later it would damage the brain. As such, I remain in the position that due to the detrimental effects of marijuana particular to ones brain there is a need to regulate its use as to only allow medical usage.
