Effects of Cannabis on Cognition and Psychology

Effects of Cannabis on Cognition and Psychology

For many years, cannabis has been the subject of controversy and inquiry. With the legalization of cannabis in several areas of the world, understanding the effects cannabis has on our cognition and psychology has become even more crucial. In this complete tutorial, we will look at how cannabis affects the brain, cognition, and psychology. We will also look at the potential advantages and disadvantages of cannabis use.

People have utilized cannabis for ages for a variety of uses. The cannabis plant contains a number of chemicals that impact the brain and body. Cannabis has two major chemicals – THC (tetrahydrocannabinol) and CBD (cannabidiol). The main psychoactive component responsible for the “high” associated with cannabis consumption is THC. On the other hand, people believe that CBD provides a variety of medical benefits and it is not psychotropic.

Understanding Cannabis

What is Cannabis?

Cannabis, often known as marijuana, weed, or pot, is a plant that contains a number of chemicals that have an effect on the brain and body. People utilize it for a variety of things, including medicine and recreation. People often smoke, vaporize, or ingest cannabis in the form of edibles or tinctures.

Types of Cannabis

Cannabis comes in three varieties: Sativa, Indica, and Hybrid.Stimulating and uplifting properties are known for Sativa strains, while relaxing and tranquil properties are known for Indica strains. Hybrid strains are a cross between Sativa and Indica and can create a variety of effects depending on the strain.

How Cannabis Affects the Brain

The Endocannabinoid System

The endocannabinoid system is a complex network of receptors and neurotransmitters that regulate a variety of physiological functions such as pain, mood, appetite, and sleep. CB1 and CB2 are the two major receptors in the endocannabinoid system. THC binds with CB1 receptors predominantly present in the brain, while CBD attaches to CB2 receptors mainly located in the immune system.


The primary psychoactive element in cannabis is THC, and it is responsible for the “high” that is associated with cannabis consumption. It operates by attaching to and activating CB1 receptors in the brain, resulting in a variety of consequences such as altered perception, mood, and cognition. In contrast, researchers believe that CBD offers a range of therapeutic benefits, including anti-inflammatory, analgesic, and anxiolytic effects, and is not psychotropic.

Effects of Cannabis on Cognition

Memory and Learning

Studies have found that cannabis use impairs memory and learning. THC has an effect on the hippocampus, a part of the brain that is important for memory creation and retrieval. Researchers have linked chronic cannabis usage to reductions in hippocampus volume and poor memory performance.

Attention and Concentration

Cannabis use has also demonstrated to impair attention and concentration. THC has an effect on the prefrontal cortex, which is responsible for attention and executive function. Chronic cannabis usage decreases prefrontal brain activity and impairs attention ability.

Executive Functioning

Executive functioning is a set of cognitive processes that are in charge of behavior planning, organization, and control. Research has proven that cannabis impairs executive functioning, particularly in jobs that require planning and organizing. Chronic cannabis usage has also been linked to decreased gray matter volume in brain areas involved in executive function.

Effects of Cannabis on Psychology

Anxiety and Depression

While some people use cannabis to relieve anxiety and depression symptoms, others claim it can exacerbate these conditions. Depending on the amount and individual circumstances, THC has been proven to cause both anxiogenic and anxiolytic effects. Chronic cannabis use has been linked to an increased risk of anxiety and depression.

Psychosis and Schizophrenia

Researchers have linked cannabis usage to an increased risk of developing psychotic symptoms and schizophrenia, especially in individuals who are predisposed to these disorders. Certain people have demonstrated psychotic-like effects, such as paranoia and delusions, due to THC. Studies have linked chronic cannabis usage to structural abnormalities in the brain comparable to those seen in individuals with schizophrenia.


Cannabis use can develop into an addiction, especially when used repeatedly and in high dosages. THC stimulates the reward system in the brain, resulting in feelings of pleasure and happiness. Tolerance, dependency, and withdrawal symptoms can result from long-term cannabis use.

Benefits and Drawbacks of Cannabis Use

Medicinal Uses

People have used cannabis medicinally for a variety of reasons, including pain relief, nausea and vomiting, muscle spasms, and seizures. CBD contains anti-inflammatory, analgesic, and anxiolytic properties, making it a possible treatment for a variety of illnesses.

Recreational Uses

People often use cannabis recreationally because it can cause sensations of relaxation, pleasure, and changed perception. However, recreational use can pose a number of risks and side effects, including impaired cognition, addiction, and legal ramifications.

Risks and Side Effects

Cannabis use can pose a number of hazards and negative effects, particularly when used frequently and in large doses. Impaired intellect, addiction, respiratory difficulties, and legal implications are examples of these.

Misconceptions About Cannabis

The gateway drug idea, which holds that consuming cannabis will lead to the use of heavier drugs, is a prevalent misperception regarding cannabis. However, research has not supported this theory, and the vast majority of cannabis users do not progress to the use of more dangerous drugs. Another common myth is that legalizing cannabis will increase use and addiction. While legalization may increase use, research indicates that it is unlikely to result in an increase in addiction rates.

The Future of Cannabis Research

Cannabis effects research into cognition and psychology is ongoing, and there are various areas of concentration for future study. Researchers need to conduct more studies to determine the long-term effects of cannabis use on cognitive function, especially in older adults. Additionally, they should investigate the effects of various cannabis strains and consumption methods. Lastly, further research is necessary to evaluate the potential benefits and risks of using cannabis for mental health treatment.


Cannabis has the potential to have numerous effects on our cognition and psychology. While some people may benefit from its use, others may suffer negative consequences. Before deciding whether or not to use cannabis, it is critical to understand how it affects our cognition and psychology. As the cannabis study progresses, we will certainly obtain a greater grasp of its effects and its applications.
