Do cannabis edibles cause eye twitching?

Getting the right answers in your cannabis journey can be tricky. But with The Cannigma’s Ask the Expert, you can find questions from readers like you, answered by a real cannabis pharmacist. 


Hi I just want to ask a question, do cannabis edibles cause eye twitching and if yes how do I make it stop?


Thanks for your question.

To try to answer your question most directly — yes cannabis could be contributing to your eye twitching problems.

Technically eye twitching could be a couple of different issues, but there are reports of this side effect.  While not common, there are reports of muscle twitches in people after they smoke THC or take THC edibles, sometimes eye twitches, other times other muscles as well.

The endocannabinoid system is all over the body, including inside the muscles and nerves responsible for moving your eyelids. The ECS also regulates the movement of electrolytes like calcium and sodium.

Therefore, since THC and other parts of cannabis interact with the ECS, and the ECS is all around the eye, its possible cannabis could be making your eye twitch worse.

There is no perfect “fix” for your problem, but you could try to reduce the twitching by taking any or all of the below approaches:

  • Reduce your dose of THC
  • Add CBD — adding CBD can modify the effect psychoactive of THC, so it may help with other effects
  • Ensure you’re well hydrated
  • Consider supplementing with magnesium or other electrolyte replacements
  • Make sure you’re getting enough sleep

I hope this helps you enjoy your cannabis more–I know those twitches can be quite annoying
