Marijuana Detox


  • Marijuana detox is necessary for removing THC from your body safely and managing complications. 
  • Most symptoms during detox are psychological and tend to respond to medications. Nonetheless, the FDA has not approved any drug to treat cannabis withdrawal. 
  • At-home detox is not usually recommended due to high interindividual differences in response to withdrawal and the potential for severe withdrawal symptoms. 
  • Medically supervised detox is safe and increases the success of addiction treatment. 

As more states legalize recreational and medical marijuana, more people are taking it than ever before. People who take marijuana as a medicine are less likely to develop an addiction. Conversely, recreational use raises the risk of developing dependence and subsequent addiction. Best marijuana detox helps such users remove marijuana and its metabolites safely from their system. 

Moreover, some users may want to detox for marijuana before a drug test. Marijuana and its metabolites can appear in the blood, saliva, urine, and hair for weeks after a single heavy use. While our body naturally flushes drugs and toxins from the body, it is often unable to do so when you take large amounts of a drug for prolonged periods. 

Besides, marijuana tends to accumulate in your fat cells. As a result, your natural detoxification system – comprising the liver and kidneys – has difficulty removing it from the body.

What Symptoms Arise With Marijuana Detox?

Marijuana detox causes uncomfortable symptoms, especially in heavy long-term users. During the first two weeks after stopping marijuana use, you may experience the following withdrawal symptoms: 
  • Cannabis craving
  • Irritability
  • Nervousness
  • Anxiety
  • Increased aggression
  • Restlessness
  • Increased anger
  • Sleep difficulty
  • Strange/wild dreams
  • Depressed mood
  • Loss of appetite
  • Unusual sweating
  • Shakiness
  • Headaches
  • Stomach pains
  • Nausea

Your doctor may ask you to take medications to relieve some of these symptoms. For example, antidepressants can help lift your mood and control anxiety symptoms, and painkillers reduce headaches. If you have a sleep problem, your doctor may give you a sleeping aid. 

These symptoms begin to wane two days after abstinence and continue to become less intense until you gain full recovery within 4 weeks. Detox professionals provide appropriate services throughout the detox and help you cope with the uncomfortable symptoms. 

How Long Does Detox Last?

Marijuana detox can last from 2 to 4 weeks, depending on:
  • How long you have been using marijuana
  • Your body fat percentage
  • The total quantity used
  • Individual metabolism 
  • Dietary habits

Is Marijuana Detox at Home Dangerous?

Though marijuana withdrawal symptoms are rarely life-threatening, experts don’t recommend at-home detox. This is because detoxing in usual environments increases the risk of relapse.
Cravings are most intense during the early few days of abstinence. Attempting unsupervised detox during this period makes you more likely to use marijuana again. 
Moreover, some heavy users may develop dangerous symptoms, such as panic attacks, excessive vomiting, and psychosis-like signs. In such medically critical situations, immediate medical care is essential. Notably, there is considerable variability in response to marijuana withdrawal. 
It is best to seek professional help from addiction specialists to improve your chances of transitioning to a drug-free life.

How Long Does Marijuana Stay in the System?
