Why marijuana affects people differently?


 Marijuana

Bhang or marijuana is a commonly used drug worldwide. According to the World Drug Report by the United Nations, the number of people who are using bhang or marijuana is high as two hundred and thirty-eight million. Therefore, this indicates that marijuana users are spread out globally. Based on the Report of the United Nation, about one hundred and thirty-five countries are engaging in the cultivation of marijuana. These countries cover about ninety-two percent of the world population.

The high number of bhang users is directly proportional to its effects. Recently, there are many cases related to marijuana users. The effects of bhang in the human body differ from one person to another. The different effects of marijuana in the body depend on its biochemistry in the body and cannabinoid genetics.  

Cannabinoids are the biologically active components in marijuana. So far two of these cannabinoids have been identified to have effects in the human body. They encompass cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC). The assessment of other cannabinoids is still going on. 

Biochemistry of marijuana in the body
The human body has two cannabinoid receptors (CB1 and CB2). CB1 mainly affects the central nervous system. CB2 mostly affects the immune system. The cannabinoid receptor activation mediates the psychoactive effects of delta-9-tetrahydrocannabinol.  

Naturally, the human body has its cannabinoids called endocannabinoids. As a result, the endocannabinoid system is present in the body. Endocannabinoid system a group of receptors and their matching antagonists. The endocannabinoid system is responsible for controlling mood, appetite, temperature, fertility and reproduction, immune function, pain, and pleasure. 

Endocannabinoids are released in the human body with the help of eating foods containing fatty acids, For example, fish and nuts. The endocannabinoids bind to cannabinoid receptors to induce different effects in the body. On the other hand, THC and CBD bind to the same cannabinoid receptors to trigger distinctive effects observed in most marijuana users. 

Normally, the effects of THC are more pronounced than the effects of CBD. THC interacts with the cannabinoid receptors in the body, resulting in different effects experienced on the body and mind. Cannabinoid receptors belong to GPCR (G-protein coupled receptors). G-proteins mediate the inhibition of the activities of adenylyl cyclase. The inhibition leads to a reduction of levels of cyclic AMP. THC stimulates cannabinoid receptors which activate potassium channels to open. 

The action reduces the period of neurotransmitter release and potential action. 2-G (2-arachidonyl glycerol), endocannabinoids and anandamide are the natural ligands responsible for the CB1 receptors. Normal functions of these ligands are responsible for memory, pain, mood, and hunger. Anandamide is generated when it is needed. Hence, it is not kept in the synaptic vesicles. FAAH (fatty acid amide hydrolase) is responsible for the inhibition of anandamide.  FAAH also acts as a deactivator of endocannabinoids by stimulating enzymatic hydrolysis.

 Endocannabinoids have longer influence as compared to THC. Endocannabinoids and THC take part in strengthening the impacts of opiates in the body. THC acts on areas that deal with memory. For instance, hippocampus, basal ganglia, prefrontal cortex, amygdala, and cerebellum. Cannabinoid receptors are concentrated in the basal ganglia, cerebellum, and hippocampus. Binding of THC with the receptors in the hippocampus results in the relocation of recent events. THC also interferes with coordination which is regulated by the cerebellum. THC also interferes with motor movement, is controlled by the basal ganglia.

Cannabinoid genetics of individuals
Different people have unique cannabinoid genetics (endocannabinoid genetics). Some people have a genetic mutation in their endocannabinoids. They are known to have good endocannabinoids. They constitute about 20% of the world population. As a result of their condition, anandamide and endocannabinoid levels increased in their bodies. Therefore, consuming marijuana has little effects in their bodies.

Bottom line:
The effects of bhang in the body are based on marijuana biochemistry in the body and endocannabinoid genetics. The cannabinoid receptors are distributed differently in the body. Moreover, different individuals have a unique distribution of cannabinoid receptors. Some areas of the brain high concentration cannabinoid receptors than others. These areas are responsible for specific functions in the body. 

So, if you consume bhang which increases the levels of CBD and THC, the areas with a high concentration of cannabinoid receptors are likely to be affected. Additionally, if people with endocannabinoid genetic mutation consume marijuana, they are less affected than their counterparts.  These differences result in the individualistic effects of bhang in people.

How to write a Forensic Case Study: Murder of Junko Furuta

Image
Photo of Junko Furuta  For one to score high marks in a Forensic Case Study, one must  adhere to the following: Background of the case: This section contains details about the crime. It includes; the reasons for committing the offense, the conditions which the crime was committed, the circumstances of the crime scene and clear identification of the suspect(s) and the victim(s). One should ensure that the information in this part gives a precise idea of what the case is all about.   Pick and Write an article on Iwriter Website Evidence: This encompasses the piece of evidence found at the crime scene. The evidence should be described in details, that is, ways in which the evidence was collected, processed and preserved.   Forensic Tests: The tests should be two or more that were used to analyze the evidence. The science or theory of instrumentation used must be described fully.   Results: This consists of a detailed explanation of the forensic ...

Roles of Sodium Carbonate when Extracting Caffeine from Tea Leaves

Image
A student failed to add sodium carbonate (Na 2 CO 3 ) when extracting caffeine from tea leaves with hot water. Though, high yield of caffeine was produced. The crystals melted at temperatures between 202  and 214 degree  Celsius. Explain. This happened because sodium carbonate did not interfere with the caffeine content of the tea leaves. Sodium carbonate (which is a base) deprotonates the phenolic hydroxyl group (-OH) (acidic) of tannins rendering them anionic. Hence, making them highly soluble in water, but parsimoniously soluble in methylene chloride. So, if sodium carbonate is not added when extracting caffeine with hot water, the extracted caffeine would also contain tannins. Additionally, sodium carbonate is added during the extraction to keep caffeine (an alkaloid which is an organic base)  in a free base form. It prevents caffeine from reacting with available acid available, which may lead to the formation cation. It reacts with a phenolic h...

Arrhenius equation: Increasing temperature increases the rate reaction

Image
The rate of reaction of a particular reaction often increases as one increase the temperature. However, how can this belief be proved using Arrhenius equation? According to the Arrhenius equation, the rate constant (k) is obtained by the ratio of Ea to RT, in which Ea denotes required energy while RT is the available thermal energy. The Arrhenius Equation is given by: k=Ae - (Ea/RT) When Ea is larger, it results in slower reactions. On the other hand, when RT is large, it leads to faster rate of reaction. Larger Ea gives smaller rate constant k, but larger RT produces larger rate constant (k). Larger rate constant increases the rate of reactions.  By using Arrhenius equation, one can easily see that when the temperature is increased, the rate constant will also increase. Let us consider these two scenarios. In the first scenario, Ea=120,000 Joules/mole, R=8.31 mol -1 K -1 , and K=373K.In the second scenario, Ea=120,000Joules/mole, R=8.31 mol -1 K -1 , and K...
