Is It Safe to Combine Kava with Alcohol?

Healthcare professionals recommend not combining kava with alcohol, as it can lead to significant liver damage and impairment. It can also affect cardiovascular activity and increase sedation, leading to drowsiness and dizziness.

How Long Does Kava Stay in Your System?

There are many factors to determine the duration of kava in your body system, including kava intake, frequent use, body weight, liver health, and metabolism. 

So, the duration of kava in the system varies from person to person. We’ll understand it later. But first, let’s find out how long it takes for kava to begin producing its effects in the body.

How Long Does Kava Take to Kick In?

If you’re looking for quick and effective results from kava use, there's good news for you! Usually, kava takes approximately 20-40 minutes for kava to start working and making you feel calm.

It also depends on how you have prepared or consumed kava. A traditional kava drink typically begins to take effect within 15-30 minutes, whereas capsules or other forms may take longer to take effect. It’s because the best kava drink is prepared directly by grinding kava roots into powder and mixing them with water. 

On the contrary, kava capsules are prepared by extracting kavalactones and mixing them with solvents. These solvents are also present in the pills, making kava less effective.

How Long Kava Stays in the System Based on Body Weight

As far as body weight is concerned, kavalactones remain in the body for a longer period, particularly in individuals with higher fat levels. It’s because higher fat content in the body can lead to slower metabolism. It means that it’ll take time for kavalactones to completely leave the body.

If you’re lean, your system is likely to eliminate kava within 48 hours; however, if you weigh more than 200 pounds, it can take up to a week. A healthy liver and less dosage speed up the metabolism process, eliminating kava much quicker.

Let’s know more about how metabolism works in your body to eliminate kava.

How Is Kava Metabolized in the Body?

Once you consume kava, it releases kavalactones in your bloodstream. These compounds interact with the brain, relieving lingering symptoms of stress and producing calming effects. Once kava is fully metabolized in your system, the liver breaks down the kavalactones and prepares them for further metabolism. 

How Long Do the Effects of Kava Last?

So, how long do you feel the effects of kava after using it? And are there specific ways to maximize its effects in your body and mind? 

What Is the Duration of Kava’s Effects?

Kava’s effects reach their peak approximately two hours after consumption and can last for several hours, depending on the individual's dosage and frequency of use. If you take a higher dose, these effects last longer, and if you take a lower dose, these effects generally fade away more quickly.

How Long After Taking Kava Can You Expect to Feel Its Effects?

As we’ve discussed earlier, kava begins working in the body much earlier, depending on whether you consume it in the form of a drink or capsules. A kava drink begins working much quicker. 

Your muscles feel relaxed. You don’t feel any stress and are finally able to achieve a sense of peace of mind! Kava induces a mesmerizing state of mind within 30 to 40 minutes. Do you want to feel this magic for longer? There are a couple of ways that maximize the effects of kava, allowing you to enjoy its calming properties for longer.

How to Maximize the Effects of Kava?

You can maximize the effects of kava in the following ways:

  • Prepare kava by kneading and blending its root powder for about 8-10 minutes if you plan on having a drink

  • Take a kava dose on an empty stomach to allow it to be absorbed quickly and effectively.

  • Consume at least two tablespoons of kava for a quick effect. Larger individuals may require more kava to achieve a more effective result.

However, you should use kava only if your liver is healthy! If you are a regular kava user, it’s essential to check your liver health frequently and detect if kava causes any adverse effects. But is it possible to detect kava in drug tests? Let’s find out.

Can Kava Be Detected in Drug Tests?

Standard drug tests, such as blood and urine samples, are used to detect kava; however, specific tests can detect kava more accurately. For example, Gas Chromatography-Mass Spectrometry (GC-MS) is used to detect kavalactones and other chemical compounds in a sample. Kava can be detectable in blood for up to 48 hours and in urine for up to 72 hours.
