How Long To Flush Marijuana Out Of Your System?

After consuming marijuana in any form, THC metabolites can stick around in your system for a while. Although the effects of marijuana wear off within a few hours, you could be looking at days or weeks to completely flush marijuana out of your system depending on how much you use.

Load Up On Water

Health professionals generally recommend drinking at least 2 liters of water a day, but those looking to flush marijuana out of their system may want to drink even more. If you have a drug test coming up soon, drinking as much water as possible in the days leading up to it will help you flush out as much THC as possible. It also helps to drink 2 liters of water a couple of hours before a drug test.

Other fluids can also help. For instance, prune juice and cranberry juice are often used as natural diuretics to speed up the excretion of THC. Things like green tea and lemon juice can also help you detox your body of weed faster.

Take Supplements

Taking certain supplements can also help you clear your body of THC faster. There are even supplements that help you mask the THC in your system, which users often use before a drug test to avoid failing.

Two supplements commonly used for marijuana detoxes are B Vitamins and Creatine. Vitamin B-12 and B-6 help speed up your metabolism and clear toxins out of your system faster. Niacin is also especially useful for cleansing your body of THC metabolites. Creatine restores flushed out creatinine from your urine, which helps ensure that you don’t fail a drug test.

Take Supplements

However, B Vitamin complex and creatine are the most useful supplements for flushing marijuana out of your system fast.

Increase Your Metabolism

Since excretion helps flush marijuana out of your system, it helps to do what you can to speed up your metabolism. Users with faster metabolisms will naturally flush marijuana out much faster. However, those with slower metabolisms can still take measures to speed up digestion.

Although exercise helps with speeding up your metabolism, it’s not recommended for those looking to pass a drug test. A study found that fasting and exercise can increase THC in the system. Therefore, it’s best to focus on dieting and avoiding exercise in the days leading up to a drug test.

Use A Detox Kit
