16 Things Weed Does To Your Body According to Science

Quality strains of marijuana are gaining mainstream acclaim, and the medical benefits of hitting the bong are only now being studied in earnest. 

Here’s 16 things that weed can do to your body and brain.

Damages Blood Vessels

The more you’re exposed to marijuana smoke, the more time your veins and arteries aren’t working as well. Over time, this can lead to less overall effectiveness which can mean extensive circulatory and cardiovascular limitations.


Exacerbates Anxiety

Though many use pot to mellow out, it can also cause our body to produce additional cortisol, which is our “stress hormone.” Over time, use can also inhibit dreaming, which increases overall anxiety, even in those who receive short-term relief from using marijuana.


Pain Relief

Certain kinds of pain, such as aches, arthritis, discomfort from cancer and cancer treatments, and muscle tightness can all be aided by the analgesic effects of smoking or ingesting marijuana. 


Impairs Memory

The brain of a lifelong pot smoker looks very similar to the makeup of a person who suffers from schizophrenia. That isn’t to say there is a link between the two, but it is to say that weed changes the way the brain operates.


Has Addictive Properties

Though marijuana doesn’t have the same heavy addictive effects that you find with cocaine, methamphetamines, crack, heroin, and other hard drugs, it does affect the reward pathway of the body, making it potentially addictive. 


Can Ease Seizure Disorders

Though testing is relatively sparse, indicators show that marijuana has reduced the likelihood of certain types of seizures, particularly those brought on by Dravet and Lennox-Gastaut syndromes.


Increases Dopamine Levels

While being used, marijuana enhances our dopamine, which is the brain’s feel-good drug of choice. By doing this, it helps combat depression for the immediate future, reduces bodily inflammation, makes socializing easier, and relaxes us.
