How does marijuana work:There are so many rumors about marijuana in the society. mostly among guys and especially those who use it.Based on the motion support your local team, most users of marijuana says it treat a lot of health problems but is that statement true?
Depending on the country’s policy marijuana may be illegal or legal. There is a nation currently allowing its people to use weed openly and this is your homework but i know that you know it.
To understand the works of marijuana is to understand how the brain work. for brain to work it needs chemicals to translate information from one brain part to the other. Depending which chemical has received the information the brain will respond accordingly. we call those chemicals neurotransmitters.
marijuana works like those neural transmitters such that the brain will have overdose of such chemicals. We know that anything that is more than normal always creates abnormal.

In details how marijuana work
Endogenous cannabinoids such as anandamide (see figure) function as neurotransmitters because they send chemical messages between nerve cells (neurons) throughout the nervous system.
They affect brain areas that influence pleasure, memory, thinking, concentration, movement, coordination, and sensory and time perception.
Because of this similarity, THC is able to attach to molecules called cannabinoid receptors on neurons in these brain areas and activate them, disrupting various mental and physical functions and causing the effects described earlier.
The neural communication network that uses these cannabinoid neurotransmitters, known as the endocannabinoid system, plays a critical role in the nervous system’s normal functioning, so interfering with it can have profound effects.
For example, THC is able to alter the functioning of the hippocampus and orbitofrontal cortex, brain areas that enable a person to form new memories and shift his or her attentional focus.
As a result, using marijuana causes impaired thinking and interferes with a person’s ability to learn and perform complicated tasks.
THC also disrupts functioning of the cerebellum and basal ganglia, brain areas that regulate balance, posture, coordination, and reaction time.
This is the reason people who have used marijuana may not be able to drive safely and may have problems playing sports or engaging in other physical activities.
THC, acting through cannabinoid receptors, also activates the brain’s reward system, which includes regions that govern the response to healthy pleasurable behaviors such as sex and eating.
Like most other drugs that people misuse, THC stimulates neurons in the reward system to release the signaling chemical dopamine at levels higher than typically observed in response to natural stimuli.
This flood of dopamine contributes to the pleasurable “high” that those who use recreational marijuana seek.
How does marijuana affect your intelligence, work and social life?
Research has shown that marijuana’s negative effects on attention, memory, and learning can last for days or weeks after the acute effects of the drug wear off, depending on the person’s history with the drug.
Consequently, someone who smokes marijuana daily may be functioning at a reduced intellectual level most or all of the time.
Considerable evidence suggests that students who smoke marijuana have poorer educational outcomes than their nonsmoking peers.
For example, a review of 48 relevant studies found marijuana use to be associated with reduced educational attainment (i.e., reduced chances of graduating).
A recent analysis using data from three large studies in Australia and New Zealand found that adolescents who used marijuana regularly were significantly less likely than their non-using peers to finish high school or obtain a degree.
They also had a much higher chance of developing dependence, using other drugs, and attempting suicide. Several studies have also linked heavy marijuana use to lower income, greater welfare dependence, unemployment, criminal behavior, and lower life satisfaction
To what degree marijuana use is directly causal in these associations remains an open question requiring further research.
It is possible that other factors independently predispose people to both marijuana use and various negative life outcomes such as school dropout.
That said, people report a perceived influence of their marijuana use on poor outcomes on a variety of life satisfaction and achievement measures.
One study, for example, compared people involved with current and former long-term, heavy use of marijuana with a control group who reported smoking marijuana at least once in their lives but not more than 50 times.
All participants had similar education and income backgrounds, but significant differences were found in their educational attainment: Fewer of those who engaged in heavy cannabis use completed college, and more had yearly household incomes of less than $30,000.
When asked how marijuana affected their cognitive abilities, career achievements, social lives, and physical and mental health, the majority of those who used heavily reported that marijuana had negative effects in all these areas of their lives.
Studies have also suggested specific links between marijuana use and adverse consequences in the workplace, such as increased risk for injury or accidents.
One study among postal workers found that employees who tested positive for marijuana on a pre-employment urine drug test had 55 percent more industrial accidents, 85 percent more injuries, and 75 percent greater absenteeism compared with those who tested negative for marijuana use.

Much has been said but there is still more to know about marijuana. Based on observation from marijuana users the effect differ from one person to another. Other marijuana users tend to be more stronger than others when they take it. You may not be lucky always sometimes marijuana can take you to a psychiatric hospital.
Other documentations says it treats cancer, glaucoma and details are given on mechanism of marijuana for producing such benefits.
