There’s a long debate over the physical effects of marijuana. Although this drug isn’t very harmful if taken occasionally in prescribed form, it becomes seriously hazardous when people become addicted to it and start taking it without prescription. In such cases it doesn’t only harm the body of the addicted person but also leaves several negative effects on the brain. In this article we’ll study about those negative effects in detail:
- Over activation of Brain’s reward system: You might’ve heard that the key ingredient of Marijuana is Tetrahydrocannabinol or THC. When a person takes migraines and marijuana, THC enters his/her brain and activates its reward system due to which the user starts feeling euphoric. This reward system is responsible for all our cheerful feelings and is activated automatically by the brain whenever something delighting happens to us. Upon activation, it releases the chemical dopamine in our nerves and we start feeling happy. On the other hand, THC activates this reward system of the brain in the same manner as most other illegal drugs do – by stimulating the brain to release dopamine. Upon release of dopamine people start feeling high and euphoric.
Relaxation is another feeling that comes along with euphoria, and once its effect is over people start feeling either sleepy or depressed.
Other feelings that may come along with migraines and marijuana and relaxation include:
Increased sensory perception
Altered time perception
Increase in appetite.
However, these effects aren’t mandatory for everyone and may vary depending on the type of person who is consuming marijuana. Sometimes Marijuana users may also suffer from panic, anxiety or distrust.
- Inability in creating new memories: The usage of marijuana kills a person’s ability to create new memories. It means the user may not be able to remember new things in future due to distorted thinking. This happens because THC affects the way in which information is processed through the hippocampus, the area of the brain that’s responsible for creation of new memories. Most of the evidence for supporting this theory comes from animal research. For example, rats that were exposed to THC showed notable memory problems in comparison to normal rats. It also hastens the neuron loss process in the hippocampus area of the brain, which further dilutes a person’s ability to learn new tasks and information.
- Distorted Thinking: Distorted thinking is another negative mental effect associated with this drug. The addicted person may become unable to do complicated tasks that require coordination (i.e. athletic activities and driving) because THC disrupts the activities of mind by binding itself to basal ganglia and cerebellum, the areas that are responsible for the coordination and balancing.
- Other effects: Those who consume the drug in large quantities may also start suffering from acute psychosis, which is a stage of mind including loss of personal identity, delusions and hallucinations.
