Personality changes due to cannabis use

Possible opportunities and risks in medical applications

The topic of personality changes caused by cannabis consumption is increasingly being discussed in our society. Personality can be altered both in the short and long term—both positively and negatively. Various individual factors such as dosage, personal predisposition, and frequency of consumption can play a decisive role.

Side effects can occur, especially due to improper use of medical cannabis. This makes it all the more important to seek medical support to maximize opportunities and minimize risks. The following guide highlights such risks and highlights the advantages that medical support can have. This helps patients find the right balance between benefits and potential negative effects.

The most important things in brief:

Long-term cannabis use can lead to personality changes, including psychological effects (1) and cognitive impairments (2).
In particular, potential risk factors must be considered, such as pre-existing mental health conditions such as psychosis (3).
If you are interested in using or treating medical cannabis, you should have it under medical supervision. This way, you can weigh the benefits and risks and find the right balance.

What is personality change and why can it occur with cannabis use?

A look at our personality reveals that it is constantly developing and changing. Factors such as social influences, biological processes, and even experiences play a crucial role. When a personality change occurs, our behavior, way of thinking, and emotions change over the long term. Cannabis consumption can also lead to personality changes, as these processes can be influenced by its effects on the brain.

The side effect of THC (tetrahydrocannabinol) is particularly crucial here. It causes neurotransmitters to be released, which in turn can influence areas such as mood or cognitive abilities (4).

The personality changes resulting from cannabis use can be as individual as the patients themselves. While some experience positive effects such as increased relaxation (5), others may experience negative effects such as anxiety (6).

IMPORTANT:

Whether and what changes occur can depend on various factors, including personal predisposition, frequency of consumption, and dosage.

The influence of cannabis on the body’s endocannabinoid system

The endocannabinoid system (ECS) is a network within the body that regulates various processes. These include reactions to stress and emotions. Within this network are receptors to which the active substances contained in cannabis, such as THC, bind (7).

As a result, signals within the brain can be influenced, resulting in various effects and consequences, such as relaxation and euphoria, but also tension and anxiety. Long-term cannabis use can also lead to long-term changes (8). This can affect mental state and personality.

Influencing factors that may play a role

A look at the influencing factors and the associated consequences of cannabis use shows that they can vary from person to person. Depending on the factors, personality changes can take different forms and vary in severity. These factors include, among others:

Genetics: Due to individual genetic predisposition, some patients may be more sensitive (9) – this particularly concerns psychological side effects.
Age: Young people, in particular, may be more susceptible to changes (10). This is due to the brain, which is still developing.
Frequency of consumption: If consumed regularly, the likelihood of long-term effects may increase.
Dosage: If the dose of THC is too high, psychological side effects from cannabis can occur. The risk of possible effects such as anxiety increases.
Strain: THC and CBD content vary depending on the cannabis strain . This can influence the effects and results.
Mental health: If you already have a mental illness, cannabis use can worsen your symptoms.

Possible short-term effects and long-term consequences of cannabis use on the brain

Cannabis consumption can produce both short-term and long-term effects and impacts on the brain. Some effects, such as altered perception, may subside after a short period of time. However, long-term consequences that are far more profound can also occur. This is primarily due to the active ingredient THC in cannabis, which can affect transmission between nerve cells (11).

The consequences of cannabis use depend on various factors, such as dosage and frequency of use. If cannabis is consumed regularly, side effects can occur, especially due to THC. These can affect, among other things, attention span (12).

Overview of possible short-term effects

Depending on the dose and personal sensitivity, various short-term effects may occur. They can occur within a few minutes or hours.

Reduction of stress and relaxation: It could have a calming and relaxing effect, which in turn could reduce stress.
Increased creativity: Cannabis may help promote creative thinking and discover new perspectives.
Changes in perception: The senses may become more intense, allowing external influences such as sounds or colors to be perceived more intensely.
Sensitive reactions to emotions: Cannabis consumption may lead to heightened feelings, both positive and negative.
Impaired perception of time: Perceived passage of time and the experience of one’s surroundings can fluctuate slightly to significantly. For example, a few minutes might feel like hours.
Development of paranoia and anxiety: There could be an increase in inner restlessness and even anxiety.

Overview of possible long-term consequences

When used long-term, cannabis may have long-term effects on the brain, causing profound changes. As a result, personality changes may occur due to cannabis use.

Psychosis: In rare cases, psychosis may be triggered—especially if there is a genetic predisposition. Symptoms include paranoia, delusions, or loss of touch with reality (disorientation and derealization).
Impairment of cognitive abilities: Memory and concentration problems may occur, and these may even worsen over time.
Schizophrenia: The risk of developing schizophrenia may be increased.
Anxiety disorder: Those affected may be more prone to anxiety attacks and increased worry in the long term.
Impulsive behavior: It may be difficult to control your impulsiveness in the long term, which could lead to rash actions.
Lack of motivation: Increased reduction in performance and lack of motivation may be perceived.
Depression: Mild to severe depressive moods may occur.
Dependence: Long-term use could lead to cannabis dependence, which can increase the need for regular and increased use.
Memory impairment: Long-term memory may be negatively affected. This is especially true for adolescents.
Exacerbation of mental illnesses: If you already have a mental illness such as an anxiety disorder, it could be exacerbated by regular consumption.

How you as a patient can benefit from medical cannabis and use it safely

Cannabis consumption is not only associated with short-term effects and long-term risks. Under medical supervision, it can also have therapeutic benefits. This is especially true if you want to treat conditions such as ADHD or arthritis and alleviate their symptoms. In this case, medical cannabis can be a useful supplement.

It’s important to use cannabis in a controlled manner to minimize unwanted side effects and avoid personality changes caused by cannabis consumption. In any case, medical advice will help you find the right strain and dosage.

Together with a doctor, you will also find the appropriate form of consumption and will receive long-term support and examination so that you can react in a timely manner to possible risks and side effects.
