Everything you need to know about marijuana (cannabis)

Worldwide, marijuana is the most widely used illicit drug. Classified as a Schedule 1 controlled substance, cannabis is a mood-altering drug that affects almost every organ in the body.

In 2017, 6 percent, or about 1 in 16 high school seniors in the United States, reported using marijuana (marijuana) every day. In the last 20 years, the number of 12th-grade graders has halved, considering cannabis use to be risky.

According to the National Drug Abuse and Health Survey (NSDUH) in 2013, there were 19.7 million or 60 drug users in the United States. people percent of people. They used marijuana the month before the U.S. survey.

People can consume marijuana, inhale it through steam, prepare it as a tea, apply it as an ointment, or eat it in products like brown or chocolate bars.

Some people use marijuana to treat chronic pain, muscle spasm, anorexia, nausea, and sleep disorders.

Medical cannabis refers to whole cannabis or its components, such as cannabidiol (CBD), which forms the basis for a limited number of approved drugs.

Medical cannabis is not subject to official standards, so its ingredients and potency are unknown. This is illegal in all states.

Quick information about marijuana:

  • The primary psychic component of ma cannabis is delta-9-tetrahydro-cannabinol (THC).
  • Marijuana contains more than 120 compounds, which probably have different properties.
  • The effects of recreational use of cannabis include lightheartedness, comfort, increased appetite, and decreased blood pressure.

What is cannabis?

Cannabis comes from the dried flowers, leaves, stems, and seeds of the cannabis Sativa (flax) tree.

People have used marijuana for hundreds of years for fiber (flax), seed oil, seeds, medicine, and recreational treatments.

There is some evidence that marijuana or some of its components such as CBD can relieve severe pain, inflammation, nausea, and chronic conditions.

However, CBD is one of at least 120 substances (cannabinoids) derived from cannabis. People have many health concerns about drug use.

Another major ingredient in cannabis is delta-9-tetrahydrocannabinol (THC).

In the case of cannabis, THC is the main psychoactive substance. It acts on specific brain receptors, potentially causing mood swings, depression, suicidal thoughts, memory problems, and disrupting general learning skills. It also increases dependence.

The compound stimulates appetite (informally known as “Mundi”) and stimulates a relaxed state, as well as other effects of smell, hearing, and sight. THC can also cause fatigue. In some people, THC may reduce aggression.


The results of more than 120 cannabinoids present in cannabis are mostly unknown, but the most potent psychoactive agent to date has been identified as THC.

When a person smokes cannabis, THC is rapidly absorbed into the bloodstream and reaches the brain within minutes.

THC is absorbed more slowly by the body when consumed, delaying the onset of action for up to 2 hours and prolonging the duration of the effect.

Cannabis THC and other cannabinoids are equivalent to cannabinoids produced by the body. These natural cannabinoids act as neurotransmitters that send chemical messages between nerve cells (neurons) throughout the nervous system.

These neurotransmitters affect the areas of the brain involved in memory, thinking, concentration, movement, coordination, time, and sensory perception, as well as pleasure. The receptors that respond to these cannabinoids also react to THC, which can disrupt normal brain function.

Some studies have shown that THC affects brain regions that regulate memory and attention.

It also disrupts other parts of the brain, adversely affecting balance, posture, coordination, and reaction time. This can make it unsafe for a person using marijuana to drive a car, operate heavy machinery, or play sports or other potentially dangerous physical activities.

THC also stimulates specific cannabinoid receptors that increase the release of dopamine, a neurotransmitter associated with feelings of pleasure.

People use marijuana to achieve a feeling of euphoria (high), dizziness, and relaxation. Marijuana also causes changes in sensory perception. The colors can look brighter, the music is louder and the emotions deeper. Some people experience feelings of paranoia.

When people use cannabis for entertainment purposes, they may experience the following effects:

• changes in perception due to a slight hallucinogenic effect that can create a distorted illusion of time and space

• mood swings, leading to euphoria, feelings of energy or a relaxed state

• higher heart rate

• lowering blood pressure

• Decreased concentration and memory

• reduced psychomotor coordination

• nausea, although some cannabinoids may help reduce nausea

• increased appetite

• faster breathing

Depending on the duration and amount of use, some traces of THC may be present in a person’s urine for several months after the last use of marijuana.


Here are some examples of findings that suggest or demonstrate some of the negative effects of cannabis use:

Crisis damage: A BMJ study found that a person is much more likely to crash their car if they drive within 3 hours of smoking marijuana.

Reproductive problems: According to a review of animal studies, cannabis use can cause sexual dysfunction.

Immune response: According to a study, smoking marijuana could eventually suppress the body’s immune system, making the user more susceptible to certain types of cancer and infections.

Psychosis: A sibling study found that long-term use of marijuana could increase the risk of developing psychosis in young adults.

Risk of gum disease: One study found that smoking cannabis increases the risk of developing gum disease, regardless of whether the user smokes.

Decreased brain function: Researchers have found that regular cannabis users who started before age 15 did not perform well on brain tests, like their counterparts who started using cannabis later in life.

Acute memory loss: A British study suggests that smokers of strong strains of cannabis (eg skunk) may be at increased risk for acute memory loss.

Changes in human DNA: A British study found convincing evidence that cannabis smoke damages human DNA in such a way that the user can become more sensitive to the development of cancer.

Testicular Cancer: A 2015 review and meta-analysis of three previous studies found that frequent or prolonged use of marijuana may increase the risk of developing testicular cancer, but more evidence is needed to confirm this.
