Like any other medicine your physician may recommend, medical marijuana can cause several side effects. Though they vary depending on your strain’s content and your administration method, one potential side effect of medical weed is slurred speech.
In addition to slurred speech, medical cannabis can also cause red eyes, hunger and giddiness. When you meet with your medical marijuana doctor, they’ll consider these side effects with consideration to your past treatments, medical history and personal preferences before deciding if the benefits of medical weed will counter its side effects.

Through an in-depth study, researchers discovered how medical weed causes slurred speech. The team found that cannabinoids, which are in all marijuana plants and total to more than 100, were involved. The cannabinoid involved was tetrahydrocannabinol (THC), which is known for its psychoactive properties.
During their research, the team found THC affected the use of the tongue. They discovered that the cannabinoid slowed down mouth muscle movements by interacting with nerve cells, which saw the flow of messages across the synapses become delayed.

Due to research efforts, the medical community understands how to prevent slurred speech from medical marijuana. Some methods include changing up your:
Even though many medical marijuana doctors recommend cannabis because of its extensive benefits, every patient is different. While one strain may work for another patient, it may not work for you. That’s why it’s essential to continue updating your physician on how you’re responding to your treatment plan and consult with them about any changes to it.
