Why does Marijuana Help Nausea?

You may be quite surprised to hear that cannabis can help alleviate feelings of anxiety. Research has been coming on leaps and bounds since the laws regarding marijuana were relaxed in most states across the US. While there is a great deal of research on cannabis with regards to reducing pain, there has only been a small amount of research into the benefits marijuana can provide in helping reduce feelings of sickness.

Why does an upset stomach occur? The vast majority of the time it is to do with your brain, rather than your stomach. A good example to highlight this is when you bump your head, you sometimes feel a bit sick. Because certain strains of marijuana are psychoactive and modify the brain’s operations, cannabis can be used to prevent the brain from triggering feelings of nausea. This is made possible due to the presence of THC in the cannabis.

What method should you be using cannabis to help treat nausea? You can either use cannabis by:

  • Smoking
  • Vaping
  • Edibles/Oils

If you are looking for immediate relief, we would recommend vaping, as using an edible can take a little while for the THC to kick in. Most people would want the cannabis to produce an effect immediately, which can happen with vaping and smoking. However, if you were to use an edible, the effects could be longer lasting.


What Evidence Supports This?

Research first started in this area around forty years ago. There was a paper published within the New England Journal of Medicine, which detailed a study of the effects THC had on feelings of nausea. It was noted in the study that no subjects were sick when they were experiencing a “high”. The finding from the study was that THC does in fact have an antiemetic effect and performs better than a placebo.

Since that study 40 years ago, research has moved on. A leading Dr in Oncology (Dr Donald Abrams) said that were wasn’t a day that went by where a patient who was suffering from cancer didn’t suffer from terrible nausea and sickness. He reasoned that cannabis was the only tonic for stopping nausea, as well as increasing a patient’s appetite. This view is widely held amongst the medical profession, as 82{1973852c3d03fa9c7b89cf4e32c90950349d2a7529a1646edaa4b9e79bec0c07} in a recent study said that they think cannabis should be used in the treatment of symptoms associated with chemotherapy.
