Is a Kava Overdose Possible?

Kava kava is an herb that has grown in popularity over recent years. Renowned for its relaxing effects, it is often served as a drink or tea and can act as a substitute for alcohol in some cases. It does so by providing similar feelings but without the risk of intoxication or hangover. As more research is done, many are left to wonder how much of this unique herb is too much. Banyan Chicago asks the question: Should we be worried about a potential kava overdose?

What Does Kava Feel Like? 

This ingredient is an anxiolytic herb that produces a sense of relaxation in the central nervous system. Taking kava is known to produce a similar buzz as an alcoholic beverage. It is extracted from the Piper methysticum plant, which is found among several Pacific Island chains. Native Islanders have used it in religious ceremonies for centuries, while Western cultures tend to use it for anxiety and stress relief in social settings. It can come as a liquid, tablet, or tea, and while it is psychoactive, it is, in fact, non-alcoholic. 

The active ingredient kavalactone is believed to interact with the limbic system. That is the part of the brain that is responsible for producing feelings of anxiety. As the kavalactones bind to these receptors, it is theorized that it naturally reduces that fear.  

Does Kava Get You High? 

While some people may experience a sense of euphoria and a heightened level of sociability, it won’t necessarily get you high in the traditional sense. People that take kava claim to remain clear-headed, something that is often sacrificed when drinking alcohol. Additionally, how buzzed a person feels may depend on the body mass index. So, someone with a lower BMI is more likely to experience a greater buzz than someone who is larger.  

Users have also reported that their tongue and lips feel numb, due to the action of specific kavalactones. Some people find this sensation pleasurable, while others may not. A warm and tingly feeling can affect the muscles, adding to the relaxed symptoms. While kava will not exactly make you high, it can produce similar, albeit less intense, effects to alcohol. 

Is Kava Addictive? 

This will depend on the person taking it. The National Institute on Drug Abuse (NIDA) defines addiction as a “chronic, relapsing disorder characterized by compulsive drug seeking and use despite adverse consequences.” In other words, choosing to consistently take a substance that affects the reward center of the brain can be classified as an addiction. 

In the case of kava, it is not currently listed as an addictive substance by the United States Food and Drug Administration (FDA). Some studies have found it can cause similar effects to those of addictive substances. By interacting with dopamine receptors and GABA, the elevation of mood can result in dependence.  

The connection between addiction and long-term health underscores the importance of professional support, like the residential recovery services offered at our inpatient rehab facility in Cathedral City, CA.
