How Long Does Weed Stay in Your System: Urine, Blood, Hair?

This is true whether the addiction is to other substances such as heroin or alcohol, or activities like gambling, shopping, or sex. Furthermore, as John C. Umhau explains, “The increased potency of cannabis over the years has caused more people to have significant withdrawal symptoms when they try to quit.” But even though more and more people are using marijuana and it is less addictive than other drugs, users aren’t exempt from the symptoms of withdrawal. By your second week, your symptoms should be must less intense than the first week, and any flu-like symptoms (changes in body temperature, headaches) will have dissipated by now. You may begin to feel restlessness, boredom, and depression creeping in.

Chronic heavy use increases the length of time that it can be detected. People may feel cravings for cannabis after they have stopped using it, especially in contexts and settings where they are used to using cannabis. THC defines the potency of cannabis products, while terpenes define the aroma and flavor. The more THC the cannabis contains, the greater the effect on the brain.

Drug tests can detect relatively small quantities of THC, and the amount of THC in a given cannabis cigarette varies. However, little research has examined how much a person must smoke to fail a drug test. A blood test may detect marijuana in blood more quickly than a urine test and up to two days from consumption.

  1. After use, cannabinoids reach the hair follicles via small blood vessels, as well as from sebum and sweat surrounding the hair shaft.
  2. It typically takes anywhere from a few days to several weeks for THC to be eliminated from the body after quitting.
  3. These include mood symptoms like depression, irritability, as well as continued difficulties with sleep, or vivid dreams.
  4. Exercise will not significantly change the rate at which the body metabolizes THC.
  5. For many people, medical detox is the first step in the recovery journey.

The first days and weeks after quitting marijuana can be a rollercoaster of thoughts, physical symptoms, and emotions. Though we provide a general timeline of typical withdrawal symptoms, everyone is different. Your experience with withdrawal is influenced by how much and how long you’ve used as well as a host of biological and psychosocial factors that make your experience wholly unique. So, use this as a general outline to mentally prepare yourself for what’s to come, but don’t be alarmed if your experience is a little different. Generally, symptoms of withdrawal begin within the first 24 hours of abstinence, peak by day three and can last for up to two to three weeks or longer.

One person’s experience with marijuana withdrawal can be quite different from another’s. However, there are some cannabis withdrawal symptoms that are more common, the severity of which depends on a host of factors, including frequency of use and overall health. Specific tests include urine, saliva, hair and blood tests, says Medical News Today.

Blood tests

The marijuana-dependent should be prepared for weed withdrawal with a wide range of symptoms that can last days, weeks, or even months. These symptoms can include irritability, insomnia, depression, loss of appetite, and intense cravings. Seeking professional help or joining support groups can aid in managing the challenges of marijuana withdrawal and provide necessary guidance throughout the process. Alcohol withdrawal symptoms can be challenging, but there are many resources available to help you get through them. Similarly, when quitting marijuana, you may experience withdrawal symptoms such as irritability, insomnia, anxiety, and changes in appetite.

The mood difficulties and physical discomforts of withdrawal peak in the first week of quitting and can last up to 2 weeks. This article will explore how and why a person can develop withdrawal symptoms from weed, as well as how to treat them. As the body stores THC in fat cells, regular exercise may help to break fat cells down and release THC into the blood for further excretion. However, while exercise might help the body metabolize more THC, exercising too near to a test may also cause a positive result due to having THC in the bloodstream.

How to Prevent Marijuana Withdrawal

This marijuana withdrawal symptom usually fades after two weeks, but some former smokers report continued symptoms for several weeks or even months. An estimated 46.9% of former pot smokers report sleep disruption issues during cannabis withdrawal. Sleep-related weed withdrawal symptoms include experiencing insomnia (trouble getting or staying asleep), unusually vivid or disturbing dreams, and night sweats.

Drug tests for cannabis measure THC and its by-products, or metabolites. These metabolites remain in your system long after weed’s effects have worn off. If a person is ready to quit cannabis use, they should make sure to take care of their body during the peak withdrawal period within the first week.

Whether you’re worried about a drug test at work or getting pulled over on the road, the age-old question – how long does weed stay in your system after quitting – can be of utmost importance. Understanding the factors that influence the duration of THC’s presence in your body is crucial for various scenarios. Let’s delve into this topic to provide you with the necessary information. They also vary in severity based on the length of time a person has used cannabis. Once the THC metabolites are stored in your hair, they will stay there until you cut your hair.

What factors affect how long THC and its metabolites stay in your system?

Tetrahydrocannabinol (THC) is the main component responsible for the euphoric high you get when using marijuana. Over time, THC stored in your body’s tissues and organs is released back into the bloodstream. When withdrawing from marijuana, you might feel extra edgy and irritable, have trouble sleeping and eating, and may even get a stomachache or headache. Some people compare it to the feeling you get when trying to quit caffeine. A 2020 review found that THC was still detected in the oral fluid of frequent smokers 72 hours after use. THC may be detected in oral fluid longer than in blood after acute use.

The number of symptoms experienced by participants was significantly linked to how often and how much marijuana they smoked. By the end of your first week, most of the physical symptoms of withdrawal will have begun to show signs of improvement—for some, these will go away completely. Even so, people may continue to struggle with sleep, lack of energy, or loss of appetite. In some people, decreased appetite may even result in significant weight loss.

As such, exercise right before a drug test may increase the likelihood of a positive test result. That range will depend on how much marijuana you use and for how long. Tests can detect THC in urine for up to 30 days in a heavy user who uses weed at least once per day.

Additionally, tests can detect THC for longer periods in individuals who use cannabis products more frequently. This is because chronic cannabis use will result in THC accumulating in fatty tissues, which will result in a slower elimination of metabolites. Whether weed is detected depends on the THC dose, the person’s body fat, their sex, how hydrated they are, if they recently exercised and their metabolism rate. “Cannabis metabolites accumulate in body fat and can take weeks to leach out of the body, so some effects of withdrawal may last a long time,” says Umhau. If you continue to feel anxious after a week of discontinuing use, seek professional help. Cannabis use can sometimes cause a substance-induced anxiety disorder.
