Marijuana can be an unpredictable drug with side effects varies according to a variety of factors including your brain’s unique chemistry, the type of marijuana used, how much you consume, and your method of consumption.

For example, if you smoke marijuana, you get it feel its side effects after inhaling, which typically lasts for another four hours. Edibles, however, can take about an hour to catch up with effects lasting up to 24 hours.

Studies on the effects of marijuana often show contrasting results, and its status in the United States as an illegal federal drug program makes it difficult for researchers to drive. large complex studies.

That said, here’s what we know so far about the short- and long-term effects of marijuana:

Short-term effects of marijuana

Marijuana contains so-called chemicals cannabinoids that interact with endocannabinoid receptors in your body brain and body. These receptors influence many different functions including pleasure, memory, thinking, movement, and perception of time. That’s why using THC, the most important cannabinoid in marijuana, can lead to the following effects:

1. It causes red eyes

Marijuana typically lowers blood pressure causing the blood vessels to dilate, which increases blood flow. “As a result, the blood vessels in the eyes expand, leading to red or‘ bloody ’eyes,” he says. Lawrence Weinstein, MD, and Chief Medical Officer in American Addiction Centers.

2. Relieve pain

Studies suggest marijuana moderately reduces pain, particularly nerve pain, muscle spasms and cancer. Researchers believe this is the case due to the liquid THC to multiple receptors in the nervous system and blocking the sensation of pain.

3. Stimulates appetite

Appetite stimulation is one of the best known of marijuana effects. It is bound to THC binding to receptors which release the hormone, ghrelin, which stimulates the appetite, says Weinstein.

4. Induces euphoria

Studies show THC increases dopamine in the brain, the neurotransmitter responsible for euphoria. This induces feelings of bliss commonly called “high feeling.”

5. Increases anxiety / paranoia

While THC can cause feelings of euphoria, consuming too much THC can cause an opposite reaction such as anxiety or paranoia.

“Dose is the crucial factor. A little can be helpful, but too much is problematic,” he says Jordan Tishler, MD, President of the Association of Cannabis Specialists.

6. Impeding judgment

Marijuana is associated with an impaired ability to strategize, solve problems, and make good decisions. However, the extent of this effect is it depends on several variables including marijuana potency and previous exposure to the drug.

For example, a study found chronic marijuana users have done poorly compared to those who are not users in tests that measure their ability to make strategic decisions.

7. Increase heart rate

After consuming marijuana, yours heart rate increases to accept lower blood pressure and provide oxygen to the body and brain, says Weinstein. For this reason, Weinstein advises people with cardiovascular conditions, such as a history of heart attack or stroke, to refrain from using it.

Long-term effects of marijuana

The long-term effects of marijuana vary from person to person, especially depending on the frequency with the drug. Most of the following effects have been documented only in chronic users, who are those who use marijuana every day for an extended period of time.

8. It can increase depression and anxiety

The majority of studies have linked marijuana use to an increased risk of psychiatric disorders including depression, anxiety and schizophrenia – particularly in people predisposed to the conditions.

But, the results of the study are conflicting: A big one Study 2016 found no association between marijuana use and mood and anxiety disorders. However, a sample of different data of American adults reported using marijuana more than once a month was associated with an increased risk of social anxiety.


For some people, marijuana use can worsen mental health problems, ”says Weinstein, noting that this is probably based on individual factors.

Therefore, if you have a family history of mental health conditions or are already diagnosed, it is best to avoid marijuana until you consult with your doctor.

9. Damage to cardiovascular health

Studies have linked marijuana use to an increased risk of:

  • Heart attack
  • Corsican
  • Atrial fibrillation (an irregular heart rate is fast)

However, more studies are needed to understand the health implications of cannabis, says the American Heart Association.

10. Causes memory loss

A great 2016 in the long run study found an association between regular marijuana use and lower scores on verbal memory tests and processing speed.

11. It can damage the lungs

Some research suggests that smoking marijuana can lead to symptoms such as chronic cough, mucus production and wheezing.

However, a 2012 study found chronic users of marijuana who smoked a joint daily for 10 years scored well on tests of measuring lung strength and capacity.

However, researchers have noted a decrease in lung strength after the 10-year mark, but lung capacity has continued to increase with greater exposure to marijuana for life.

12. Helps with weight loss

While cannabis can stimulate appetite, several studies show an association between the long run cannabis use and a reduced body mass index (BMI), even in users who eat more calories than those who are not users.

U The average American diet is characterized by a high intake of sugar and starchy foods, Which researchers theorize can cause an imbalance in the body’s endocannabinoid system. Cannabis is believed to “reverse” this imbalance, causing the body to burn and retain calories more efficiently.

13. Impede development

The effects of marijuana on brain development are unclear and probably varies depending on:

  • Age when you start using it
  • How much do you use
  • What type of marijuana do you use
  • Genetics

Mostly studies suggests that regular marijuana use in adolescents is associated with reduced volume in certain regions of the brain that could lead to reduced brain function. However, others note no structural difference between the brains of marijuana users versus nonusers.

14. Increases the risk of dependence

U The Centers for Disease Control (CDC) suggests one in 10 marijuana users will become addicted. That number increases to one in six in people who start using it before the age of 18.

Like other addictive drugs, Liquid is associated with the release of dopamine which “teaches” the brain to continue to use it.
