Cannabis, also known as marijuana, has been the subject of debate in recent years due to its legalization in several countries and its medicinal use. Despite its potential benefits, it is essential to know and understand the risks associated with its consumption. In this post, we will present a detailed view of the dangers of using cannabis.

What is cannabis?


Before delving into the risks, it’s vital to understand what cannabis is. It is a plant whose components, mainly THC (tetrahydrocannabinol), have psychoactive effects on the human body. Marijuana, hashish, and hash oil are some of the products derived from cannabis.

Short-term risks

Psychological alterations

One of the most immediate effects of cannabis is mood alteration. This can result in feelings of euphoria, but also paranoia, anxiety, or hallucinations.

Memory problems

Cannabis consumption can affect the ability to remember recent events, making it difficult to learn and retain new information.

Coordination problems

THC affects motor coordination, which can increase the risk of accidents if, for example, one drives after consuming.

Long-term risks



Although many people believe that cannabis is not addictive, prolonged use can lead to psychological and, in some cases, physical dependence.

Lung problems

Smoking cannabis, like tobacco, can lead to lung problems, including chronic bronchitis.

Mental problems

Long-term consumption is associated with an increased risk of developing mental disorders such as schizophrenia or depression, especially in people with a genetic predisposition.

Cognitive problems

Continuous consumption can affect cognitive abilities, such as memory, attention, and decision-making.

Cannabis and young people


Young people are especially vulnerable to the risks of cannabis. Their brain is still developing, so the effects can be more harmful and lasting. It is essential to educate and talk to them about the dangers of its consumption.

Are there benefits to using cannabis?


While we have detailed the risks associated with cannabis use, it is important to mention that there are studies that support its medicinal benefits, such as relieving chronic pain, muscle spasms, or reducing anxiety. However, it is crucial that its use is supervised by a doctor and is done responsibly.

Cannabis is a substance that, like any other, has both benefits and risks. It is essential that each individual is informed and makes conscious decisions about its consumption. Moderation and education are key tools to avoid the dangers this plant can bring.


If you decide to use cannabis, or know someone who does, it is vital to be aware of the risks and seek medical guidance if any adverse effects occur. Health should always be our priority.‌
