Cannabis has become one of the heated topics across the globe, not only for its potential benefits but some side-effects that it may cause on the human mind and body. The drug has helped a wide range of patients coming from different age groups. Health conditions such as cancer, epilepsy, etc have been treated by medical marijuana.

Patients often take MMJ cards to seek marijuana legally. For instance, if you are a resident of San Jose, then you can easily get the San Jose medical marijuana card (MMJ) for your health. With the legalization of medical marijuana in almost all the US states, people think that the drug has a lot of potentials which is true also. But do you know how exactly it affects your body and brain? Let’s read about that below-

Marijuana’s Effect On Brain

In order to understand marijuana’s effect on the brain, first, we need to understand that it depends on the different types of strains. It varies on the plant’s chemical composition and the growing technique used. The main psychoactive ingredient delta-8 THC (Tetrahydrocannabinol) interacts with the brain’s cannabinoid receptors.

Now, these receptors are connected to nerves in the brain which influence emotions such as pleasure, thought, concentration, memory, and coordinated movement. That is why you feel excited after taking the weed. The high feeling you get from cannabis is because of the THC which is found in varying potency.

THC interacts with the hippocampus, a part of the brain which is responsible for altering the way information is processed and how memories are found. Research suggests high consumption of THC by adolescents can cause cognitive impairment and brain cell loss. That being said, studies have also shown that marijuana helps slow down the progression of Alzheimer’s disease.

Marijuana Makes You Feel Good 

One of the main reasons why weed is popular is because it makes you feel good. The majority of youngsters use marijuana for recreational purposes as it helps them to deal with daily life stress and tiredness. The THC compound when interacts with the brain’s receptors, produces dopamine, a feel-good chemical in the brain.

The more you consume marijuana, the more it excites you. However, one needs to keep in mind that excessive dosage of cannabis can lead to negative effects such as anxiety, uncontrolled emotions, etc.

Marijuana’s Effect on Body 

There are different ways of consuming weed and how you consume can have different types of effects on your body.
