Marijuana, one of the most common recreational drugs worldwide, has generated much controversy in terms of its health effects. Although many advocates argue in favor of its medicinal and recreational use, several studies have shown that excessive and continued consumption of this substance can have significant negative effects on the brain and mental health of people.
1. Decreased cognitive function
One of the most studied negative effects of marijuana on the brain is its impact on cognitive function. The use of this drug can interfere with memory, attention, concentration and learning ability. These effects are especially worrying in adolescents whose brains are still developing, since marijuana use at this stage can have long-term repercussions on their cognitive ability.
2. Alterations in brain development
Marijuana use during adolescence and early adulthood can affect brain development. Studies have shown that frequent use of this drug can alter the structure and function of various brain areas, such as the hippocampus, prefrontal cortex and limbic system. These alterations can have long-term consequences on people's mental and emotional health.
3. Increased risk of psychotic disorders
Another negative effect of marijuana on the brain is its association with an increased risk of psychotic disorders, such as schizophrenia. The use of this drug, especially in people with a genetic predisposition to psychotic disorders, can trigger acute psychotic episodes or worsen symptoms in those who already suffer from such disorders.
4. Impact on mental health
Marijuana use can also have negative effects on people's mental health. Chronic use of this drug has been found to be associated with an increased risk of depression, anxiety, and personality disorders. In addition, it can worsen the symptoms of pre-existing mental disorders and make their treatment more difficult.
5. Dependence and withdrawal syndrome
Despite being considered a drug with less addictive potential compared to other substances, marijuana can generate psychological dependence in some users. Those people who consume this drug regularly and in large quantities may experience withdrawal symptoms when trying to reduce or stop their consumption, such as irritability, mood swings, insomnia and anxiety.
6. Alterations in sensory perception
Marijuana consumption can alter people's sensory perception, which can manifest in the form of visual, auditory and tactile distortions. These effects may be temporary, but in some cases, especially in sensitive people or with high doses, the sensory alterations can be intense and disturbing.
7. Reduced sleep quality
Another negative effect of marijuana on the brain is related to sleep. Although this drug can help you fall asleep in the short term, its regular use can interfere with normal sleep cycles, causing difficulty falling asleep, disruption of REM sleep, and a lower quality of night's rest overall.
8. Impact on motor coordination
Marijuana use can affect people's motor coordination and responsiveness. This can increase the risk of accidents, especially when driving or operating machinery, as the drug can slow reaction times and decrease perception of reality.
9. Impaired lung function
Using marijuana regularly and through inhalation of smoke can have negative effects on people's lung function. Like tobacco, marijuana can irritate the airways and lungs, which can lead to chronic cough, bronchitis, and other long-term respiratory problems.
In conclusion, while marijuana can have therapeutic benefits in certain contexts, its excessive and continued consumption can have harmful effects on the brain and mental health of people. It is important to take these risks into account and seek professional help if you experience difficulties related to the use of this drug.
