Methamphetamine Epidemic: A Case Study

With the rise of the “ice epidemic” and media accounts of the terrible impacts of methamphetamine, its legitimate medical uses has been relegated to the background. Methamphetamine is highly addictive and affects the central nervous system, (NIDA, 2013). The drug is classified as a Schedule 8 or dangerous drug of addiction (DDA) in Australia due to its high potential for abuse. It is only available through a doctor’s prescription in America (Medical News Today, 2014). Thus, this essay will investigate whether methamphetamine should be used to treat obesity using the medicine, desoxyn. Biochemistry behind the issue - (marked as KU1, KU2, KU3 on SACE Rubric) (words: 352) Figure 1: The interaction of methamphetamine in the neuron …show more content…

The transporter molecule, known as dopamine active transporter (DAT), which usually transports dopamine or norepinephrine, carries the methamphetamine to the nerve cell terminals (NIH, 2009). The methamphetamine causes an increased release of the neurotransmitters (dopamine or norepinephrine) in the brain (Macalester, 2008). The methamphetamine however blocks the reuptake of the dopamine because the drug alters the DAT by making it reverse instead of transporting the chemical back to the presynaptic neuron, (NIH, 2009). As shown in figure 1 the methamphetamine travels its way to the dopamine receptor on a vesicle and blocks up the dopamine transporter (NIH,2009). As an increased level of dopamine reaches and builds up on the postsynaptic neuron the person feels a sensation of euphoria for a short amount of time, (Medical News Today, 2014). The postsynaptic neuron is responsible for receiving neural information from the presynaptic neuron and determining whether the information is valuable to send to other neurons or send back to presynaptic neuron (NIH,2009). As the euphoric effects mentioned above are the blame for the misuse, addiction and physical and psychological side-effects, the molecule has medical purposes. Methamphetamine is …show more content…

Desoxyn has proven efficacy in elevating the mood as well as suppressing the appetite in obese people allowing them to achieve their weight loss goals, (PDR health, 2015). Patients prescribed this medicine may experience depression due to their weight and failed weight-loss treatments, thus desoxyn can be a key advantage for them because it reduces weight, elevates the mood, increases attention and motivation. Desoxyn has been shown to cause more weight loss when taken alongside a dietary management, compared to people taking a dietary management alone (PDR, 2015). This evidence demonstrates that the medicine is most effective when taken alongside a dietary management

The Methadone Train Addictions to opiates, and opiate derivatives, are some of the most prevalent and long-standing drug abuse issues known. These abuses have also contributed to other social problems such as the spread of HIV/AIDS and Hepatitis C due to needle injection being a popular method of delivery. In the 1960s, methadone, a synthetic opiate substitute, was introduced as the preferred medical treatment for opiate abuse and addiction and remains so today. Reduction of disease distribution is only one of its heralded benefits. Methadone is commonly used in management of withdrawal symptoms related to addiction to heroin and other opiate drugs, both prescription and non-prescription.

Methadone exists as two enantiomeric forms, R and S (Eap et al., 2002). The most commonly used form of methadone in maintenance treatment is the racemic mixture (RS- methadone) (Groman et al., 1997). It is the R-isoform that gives most of the opioid effects (Eap et al., 2002). Methadone exerts its analgesic and narcotic effects through the µ-OR subtype, and has antagonistic effect at the NMDA receptor (Trescot et al., 2008). The antagonistic effect at the NMDA receptor is believed to be advantageous in preventing induction of tolerance (Callahan et al., 2004).

This is almost the same high a powder cocaine user experiences, but bigger increments of dopamine are released. The addiction of crack comes from the brain because dopamine is a type of reward system for the brain that provides the brain with pleasure. The center for substance abuse research states, “After having tried Crack Cocaine, the user will rapidly develop an intense craving for the drug since the chemistry of the brain’s reward system has been altered” (Ceaser). The human body also becomes tolerant of this drug. In most cases in life this tolerance is a good thing, but when it comes to using drugs in order to get high it can be very deadly.

Drugs are substances that trigger temporary changes in the body which may result in such a pleasurable and relaxing effect. Some of the types can slow down the nervous system’s action, while other types can have the exact opposite effect; spurring the nervous system into rapid action. Drugs are connected to cravings or addiction since a person’s body starts yearning for drugs after he or she has taken it for a while. Drugs affect consciousness significantly! They may cause people to hear or see things that aren’t real (hallucinations), experiencing mood swings, or may even distort people’s perceptions.

All these characteristics led to the conclusion that drug addiction is a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use. It is considered as a brain disease because drugs change the structure of the brain, and how it works. Every drug affects different systems of the brain. For example, in the case of cocaine, as the brain is adapted in the presence of the specific drug, brain regions responsible for judgment, decision-making, learning, and memory begin to physically change, making certain behaviors “hard-wired.” In some brain regions, connections between neurons are pruned back.

Drug Addiction : Treatment or Punishment? When a person takes a drug the chemicals affect the brain by interfering with how the neurons send messages. According to the National Institute on Drug Abuse, the structure of Marijuana and Heroin mimic a natural neurotransmitter which tricks the receptors into allowing the drug to activate neurons inside the brain which interferes with messages and leads to abnormalities of behavior. With other drugs such as cocaine there is an abnormally large amount of neurotransmitters released which disrupts communication channels.
