The Benefits and Harms of Marijuana

Let’s look at the damage marijuana does to our health, and how much it compares it to good. After all, the plant is used not only to achieve a narcotic effect but also in medicine for the treatment of life-threatening diseases, as well as in some industries.
In some countries, the use of marijuana is legal, in others, it is strictly prohibited.

What is Marijuana

Cannabis is a common plant that contains psychoactive substances of cannabinoids. It is also called marijuana, hemp, hash.

Marijuana happens sowing, Indian, and weed. Each species contains a different amount of cannabinoids. In the weed – they are the least.

To achieve the euphoric and hallucinogenic effects of marijuana, you can:

  • chew;
  • add to tea and various dishes, which is very dangerous due to a possible overdose;
  • use in the form of rectal suppositories.

Despite the large number of uses, intravenous injections with marijuana are extremely rare.

Marijuana in Medicine

The use of marijuana for medical purposes dates back to the XVIII century BC. The plant was used in ancient India and the Middle East as an anesthetic, antiepileptic, anticonvulsant, antiemetic.

To date, the effectiveness of the plant for therapy has been proven:

  1. Alzheimer’s disease. Modern medicine does not know how to deal with senile dementia. But ordinary hemp can inhibit the development of pathology.
  2. Epileptic seizures. The plant reduces their number by 54%.
  3. Multiple Sclerosis.
  4. Oncology.
  5. Type II diabetes mellitus.
  6. Asthma. Due to its anti-inflammatory properties.
  7. Erectile dysfunction.
  8. Hepatitis C.

Marijuana is an excellent painkiller that can quickly relieve pain, including with multiple sclerosis and arthritis.

Despite proven medicinal properties, marijuana should not be used without the permission of a doctor. After all, all the positive qualities of the plant can be reduced to zero by its negative effect on the body.

The Effects of Marijuana On the Body

Cannabis has a stimulating and sedative effect, and at high doses, hallucinogenic effects on the body. This is expressed in numerous manifestations.

Physiological level

In a person exposed to marijuana, the mucous membrane swells and the eyes become inflamed, the pulse quickens, the heartbeat intensifies, and blood pressure rises. Also, motor activity is disturbed, body temperature fluctuates. Perhaps the appearance of headaches, dizziness, feelings of nausea, increased appetite.


A person in a state of drug intoxication feels relaxed, his psychomotor activity decreases, his attentiveness worsens. He can talk quickly and without restraint.


Imaginary well-being, a state of euphoria, carelessness can be sharply replaced by anxiety and even aggressiveness.

Mental Disorders

A person worsens short-term memory, a general understanding of what is happening around. He is not able to fulfill the task set before him, even an easy one. At the same time, an increase in tactile sensitivity is observed, the pain threshold is reduced, visual and auditory perception and sense of smell are aggravated. The addict ceases to be aware of himself as a person. With a large dosage, the appearance of hallucinations and psychoses is not excluded.

It is from the above signs that one can determine a person’s drug intoxication, as well as identify addiction in his friends and relatives.

9 Symptoms of an Overdose

An overdose of marijuana leads to:

  1. Cramps.
  2. Dilation of the pupils, redness of the face.
  3. Increased appetite.
  4. Tachycardia and increased blood pressure.
  5. Impaired speech function.
  6. Heartache.
  7. Acute psychosis, the appearance of panic, paranoia, suspicion, delirium.
  8. Circulatory disorders in the brain.
  9. Recurring hallucinations (in some cases, even after six months of abstinence).

In theory, a fatal outcome from an overdose of marijuana can be assumed. But in order for it to come, it is necessary to increase the dosage by 40,000 times.

In any case, with the appearance of overdose symptoms, the help of a doctor is required.

The effect of marijuana on the organs and systems of the body

Cannabinoids are fat-soluble substances that primarily affect the brain, lungs, and reproductive system. In addition, they have a negative effect on the body at the cellular level: they alter biochemical processes and cellular metabolism, which leads to a slowdown or complete cessation of cellular activity.

At the same time, there is no accurate evidence of the negative effect of marijuana on the body.


In the process of research using modern accurate methods, it was found that there are no anatomical changes in the brain in people who consume marijuana for a long time, even in large doses.

In any case, when cannabis is consumed, cognitive abilities weaken, understanding, abstract thinking are disturbed, a person becomes practically unable to learn.

An individual reaction can be expressed not only in euphoria but also in anxiety, toxic psychoses.

Respiratory System

The effect of smoking marijuana is similar to the effects exerted on the respiratory system by smoking. A bad habit causes a risk of bronchitis, pharyngitis, sinusitis, malignant processes.

The Cardiovascular System

The direct effect of hemp on the cardiovascular system has not been established. Heart and vascular diseases are diagnosed only in 2% of plant consumers.

It should be borne in mind that the use of cannabis in any form leads to increased heart rate, increased heart rate, increased blood pressure. Such manifestations are quite dangerous for a person suffering from cardiovascular pathologies.

Reproductive system

With prolonged smoking of marijuana in men, the level of testosterone, which is the main male sex hormone, is significantly reduced. A strong change in the hormonal background, leading to sexual dysfunction, is not ruled out.

Some experts believe that marijuana enhances sexual desire, but at the same time, sexual stamina decreases.

Marijuana causes sexual desire in women, but at the same time leads to a change in hormonal levels and affects the likelihood of conception. However, experts have not established a connection between marijuana and infertility.

There is no evidence of the development of chromosomal or genetic damage to the fetus during pregnancy, miscarriages, and deformities associated with the consumption of cannabis.

Other experts talk about the strong toxic effects of marijuana on the fetus, the severe course of childbirth and pregnancy, developmental disabilities, and the frequent death of newborns.

Plant dependence

Marijuana develops a dependence on 9% of people who consume the plant. This is not very much compared with the dependence on other substances, for example, nicotine – 32%, alcohol – 15%.

Prolonged use of marijuana is dangerous:

  • social self-isolation;
  • transition to the use of more “hard” drugs;

The withdrawal syndrome is characterized by the following symptoms:

  • nausea, diarrhea;
  • loss of appetite;
  • chills, sweating;
  • tremor;
  • intolerable pain syndrome;
  • sleep disturbance;
  • irritability, depression, anxiety.

This condition can last for several hours or a week.


Modern medicine does not provide accurate evidence of both the harm and benefits of marijuana.

Each person decides on the possibility of using the plant. And if the use of cannabis for medical purposes can justify itself, then you should not try to achieve euphoria with it and make a bad habit out of it.
