Marijuana And The Juvenile Justice System

The first juvenile court in the United States was established in Illinois in 1899. The juvenile justice system was founded on the principles of rehabilitation, with a focus on the offender, not the offense. In the 1950s and 1960s, many began to question the ability of the juvenile court to effectively rehabilitate delinquent youth by the 1980s, the pendulum began to swing away from lenient approaches and toward more severe sanctions for juvenile offenders. The 1990s completed this turnabout as...

The Respiratory System

The scientific community seems to agree that damage to the lungs is the main physiological risk from marijuana because smoking is the preferred method of getting high from marijuana. This may be because the effects from marijuana are almost instantaneous when inhaled. In other words, THC bypasses the digestive system and goes directly from the lungs into the bloodstream. Indeed, after an extensive scientific investigation, experts at the Institute of Medicine found that the health effects from...

Reinforcement The Key Motivator

One of the keys to understanding psychological dependence on marijuana is the concept of reinforcement. This is viewed by many experts as the underlying motivator of drug-taking behavior. Some researchers even believe that psychological dependence, based on reinforcement, is the driving force behind drug addiction. Reinforcement occurs when a teen receives a pleasurable sensation from using marijuana and is then motivated to use marijuana again to achieve the same pleasurable experience. The...

Agonists And Antagonists

Remember, the primary job of the neurotransmitter is to fit or lock into its own particular receptor, and then to initiate specific physiological responses within the body. However, many drugs, such as THC, are able to bind or attach themselves to a specific receptor, thus mimicking or blocking the normal function of the neurotransmitter destined for that receptor. Some drugs are agonists that activate or turn on receptors, and some are antagonists that block receptor function. It is not even...

Recovery

Once a frequent marijuana user clears the drug from the body and passes through any withdrawal symptoms, the journey to recovery begins. This is not an easy journey. It requires a complete reorganization and restructuring of thought processes, attitudes, and lifestyle. A marijuana-dependent teen may have organized nearly all daily thoughts and routines around obtaining or using marijuana. Recovery involves a conscious and deliberate effort to create new, more socially productive ways of...

Set

Set is a person's expectation for the type of effect he or she will experience after using marijuana. This expectation is created by a person's total past experience-what he or she has ever heard, read, seen, or thought about encounters with marijuana. Sometimes teenagers (just like adults) do not really know what their deep-down feelings are about using marijuana. One person could feel eager to fit in with friends and could think smoking marijuana is cool, but really be scared of what might...

Tolerance And Dependence

The concept of tolerance is important in understanding the properties and effects of marijuana. Tolerance can be defined as the need for increasing doses of a drug over time to maintain the same effect achieved at previous lower doses. Receptors in the brain develop a tolerance to THC. Since the body becomes tolerant to the effects of marijuana, heavy users often feel a decreasing effect from the drug and thus may need to smoke ever-increasing quantities to achieve the earlier high. Because of...

Willingness to Break Social Norms and Violate the

Many experts observe that social norms about a drug are deeply influenced by the drug's legal status and whether or not it is considered dangerous. Since marijuana is illegal and considered by many to be harmful, its use is discouraged by most of today's American society. Yet, teenagers as a group often rebel against societal norms. Hence, it is not surprising that many teens use marijuana, or at least experiment with it, despite the consequences of clashing with parents, school authorities,...

Zero Tolerance

The concept of zero tolerance drives much of today's legal and educational policy. The zero tolerance policies teach that using marijuana even once puts the user at risk for dependence and abuse of the drug. Most drug education programs are built around this zero tolerance message. Proponents of this policy stress that the purpose of drug education is to prevent drug experimentation therefore, the topic of drug use is practically forbidden. In addition, as part of this zero tolerance policy,...

Endogenous Internally Produced Cannabinoids

Thc Action

There are many examples of naturally-occurring plants that contain drugs that interact with neuronal receptors, including THC, nicotine, morphine, LSD, and cocaine. The effects that result from the use of these drugs, both desirable and undesirable, are determined through their actions at specific receptors. Scientists have long wondered why nature would create receptors in the human body that could be activated by chemicals in plants. Clearly, these receptors did not evolve simply to recognize...

An Introduction To Cannabis Sativa

Differents Types Indian Drugs

The chemical compounds primarily responsible for the psychoactive and medicinal properties of the hemp plant are concentrated in an aromatic, tar-like resin in the flowering tops of the Indian hemp plant (Cannabis sativa). This resin tends to be most potent in the female plants, especially when they are cultivated before the seeds form. (They are also known as sinsemilla, a Spanish word meaning without seed.) It is said that the hemp plant produces the resin as protection from heat in order to...

How Are Teenage Trends And Attitudes Measured

Department of Health and Human Services (HHS) tracks the nation's substance abuse patterns through three major surveys The National Household Survey on Drug Abuse (NHSDA), the Monitoring the Future (MTF) Survey, and the Drug Abuse Warning Network (DAWN). Statistical information from these surveys helps the United States identify potential drug abuse problem areas in order to set national drug policy and devote financial resources that target areas of greatest need. Data from these...

Reassurance about the Safety of Marijuana

Experts speak of perceived risk versus perceived benefit when attempting to understand the teenage trends of marijuana use. Most of our everyday decisions are based on a balanced scale of these two ideas. When deciding to do something, we weigh the pros and cons the benefits and risks and then make our decision. It is commonly believed that this risk benefit assessment is a primary factor in determining whether or not a teen will use marijuana. In addition, studies show that information about...

Routes Of Exposure

How does marijuana affect the body To answer this question, we must ascertain how THC gains access to the body the route of exposure . Routes of exposure may be as important as dose when considering implications to human health, since they strongly influence the body's response to marijuana. The major routes through which marijuana may enter the body are inhalation and ingestion. The greatest effect with the most rapid response is produced when THC is inhaled. This is because smoking bypasses...

The History of Marijuana

Marijuana is the flowering part of the Indian hemp plant Cannabis sativa, a weed-like species that grows wild and is also cultivated in many tropical and temperate parts of the world. Cannabis means hemp in Latin and is derived from the Greek word kannabis. Marijuana probably comes from the Mexican Spanish marijuana marihuana Mary's leaf or plant or from Maria and Juan Mary and John . Among its many names, marijuana is commonly known as weed, ganja, mary jane, and pot. For thousands of years,...
