Short-Term Effects
Euphoria and relaxation
When you consume cannabis, one of the first effects you may experience is a sense of euphoria and relaxation. This is due to the psychoactive compound in cannabis called delta-9-tetrahydrocannabinol (THC), which interacts with the brain’s reward system. You may feel a heightened sense of pleasure and an overall sense of well-being.
Impaired memory and cognitive function
While the initial effects of cannabis may seem enjoyable, it’s important to note that it can also impair your memory and cognitive function. THC can interfere with the normal functioning of the hippocampus, a region of the brain responsible for the formation of new memories. This can result in short-term memory loss and difficulty in retaining new information.
Distorted perception
Another short-term effect of cannabis is distorted perception. THC binds to cannabinoid receptors in various parts of the brain, including those that regulate perception and sensory processing. As a result, you may experience alterations in your senses, such as changes in color perception, heightened sensitivity to light and sound, and a distorted perception of time.
Increased heart rate
When you consume cannabis, your heart rate may increase temporarily. THC binds to cannabinoid receptors in the cardiovascular system, leading to dilation of blood vessels and increased blood flow. This can result in a faster heart rate, known as tachycardia. It’s important to note that this effect is generally mild and temporary, but individuals with pre-existing heart conditions should be cautious.
Difficulty in coordination and motor skills
Cannabis can also affect your coordination and motor skills. THC affects the cerebellum, which plays a crucial role in the coordination of movement. As a result, you may experience difficulty in performing tasks that require precise movements, such as driving or operating machinery. It’s crucial to avoid activities that require focus and coordination while under the influence of cannabis.

These changes can affect cognitive function, emotional processing, and decision-making abilities.
Risk of addiction
Regular use of cannabis can also lead to the development of addiction. While not everyone who uses cannabis will become addicted, individuals who start using at a younger age and use it frequently are at a higher risk. Cannabis addiction can have a significant impact on various aspects of your life, including relationships, work, and overall well-being.
Cognitive impairments
Long-term cannabis use has been associated with cognitive impairments, particularly in individuals who began using at a young age. Studies have shown that prolonged exposure to THC can affect attention, memory, and executive functions, which are essential for problem-solving and decision-making. Chronic cannabis use during adolescence has been associated with a decrease in IQ.
Psychiatric disorders
There is a connection between cannabis use and an increased risk of developing psychiatric disorders. Regular cannabis use has been linked to an increased risk of anxiety disorders, depression, and psychosis. Individuals with a predisposition to mental health disorders may be more vulnerable to the negative effects of cannabis.
Impaired educational attainment
Cannabis use during adolescence has been shown to have a negative impact on educational attainment. Studies have found that regular cannabis use during adolescence is associated with lower academic achievement, poorer school performance, and an increased likelihood of dropping out of school. It’s crucial to understand the potential consequences of cannabis use on educational goals.
Effect on Adolescent Brain Development
Increased risk of mental health disorders
Adolescence is a critical period of brain development, and cannabis use during this time can have long-lasting effects on mental health. Research has shown that regular cannabis use during adolescence is associated with an increased risk of developing mental health disorders, such as anxiety and depression. The developing brain is particularly vulnerable to the negative effects of THC.
Impaired cognitive function and IQ
The adolescent brain is still undergoing significant development, and regular cannabis use can interfere with cognitive function and IQ. Studies have found that individuals who started using cannabis during adolescence and continued using it in adulthood had lower IQ scores compared to non-users. Cannabis use during this critical period can disrupt the normal trajectory of brain development.
Potential long-term impact on brain structure
Regular cannabis use during adolescence may have long-term effects on brain structure. Studies have shown that early and frequent cannabis use can lead to changes in the volume and connectivity of brain regions involved in memory, attention, and cognitive control. These structural changes may persist into adulthood and have implications for cognitive function and mental health.
Effect on Adult Brain Development
Potential cognitive impairments
While the majority of research on cannabis’s effects focuses on adolescent brain development, it’s important to consider its impact on adult brain development as well. Regular cannabis use in adulthood has been associated with cognitive impairments, particularly in attention and executive functions. Chronic cannabis use may affect your ability to concentrate, problem-solve, and make decisions.
Increased risk of mental health disorders
Adults who use cannabis regularly are also at an increased risk of developing mental health disorders. Research has shown that prolonged cannabis use is associated with an increased risk of anxiety disorders, depression, and psychosis. The relationship between cannabis use and mental health is complex and influenced by various factors, including genetics and individual susceptibility.
Impact on brain connectivity
Chronic cannabis use in adulthood can impact brain connectivity. Studies have found changes in the functional connectivity between brain regions involved in cognitive processes and emotional regulation. Altered brain connectivity may contribute to cognitive impairments, emotional dysregulation, and an increased risk of mental health disorders.
Effect on Memory
Short-term memory impairment
One of the most well-known effects of cannabis is short-term memory impairment. THC affects the hippocampus, a brain region involved in the formation of new memories. When THC binds to cannabinoid receptors in the hippocampus, it disrupts the normal functioning of this region, leading to difficulties in remembering recent events or information.
Interfering with the consolidation of long-term memories
In addition to short-term memory impairment, cannabis use can also interfere with the consolidation of long-term memories. Studies have shown that THC can disrupt the process by which memories are stabilized and stored in the brain. This can lead to difficulties in retaining and recalling information over an extended period.
Effect on Attention and Concentration
Decreased ability to focus
Cannabis use can impair your ability to focus and concentrate. THC affects brain regions involved in attention, such as the prefrontal cortex and the anterior cingulate cortex. When these regions are impacted by THC, it becomes more challenging to filter out distractions and maintain sustained attention on a given task.
Impaired attention span
Similarly, cannabis use can lead to an impaired attention span. The psychoactive compounds in cannabis can disrupt the normal functioning of brain networks responsible for sustaining attention over time. This can result in difficulties in maintaining focus, especially during tasks that require sustained attention and concentration.
Effect on Decision-Making
Impaired judgment and decision-making abilities
Cannabis use can impair your judgment and decision-making abilities. THC affects brain regions involved in decision-making, such as the prefrontal cortex. When THC binds to cannabinoid receptors in these regions, it can interfere with their normal functioning, leading to impaired judgment, impulsivity, and difficulties in making sound decisions.
Effect on Brain Chemistry
Interaction with neurotransmitter systems
Cannabis interacts with various neurotransmitter systems in the brain, including the endocannabinoid system. THC, the psychoactive compound in cannabis, binds to cannabinoid receptors, affecting the release and reuptake of neurotransmitters. This interaction can influence the overall balance of neurotransmitter activity in the brain and impact various brain functions.
Altered release of dopamine
One of the neurotransmitters affected by cannabis use is dopamine. THC can increase the release of dopamine in the brain’s reward system, leading to feelings of pleasure and euphoria. However, chronic cannabis use can disrupt the normal release and regulation of dopamine, potentially resulting in changes in reward processing and motivation.
Effect on Neuroplasticity
Potential impact on brain’s ability to rewire and adapt
Neuroplasticity refers to the brain’s ability to rewire and adapt in response to experiences and environmental changes. Chronic cannabis use has been shown to impact neuroplasticity, potentially affecting the brain’s ability to adapt and rewire neural connections. This may have implications for learning, memory, and recovery from injury or disease.
