- It’s a decision you need to make for yourself, but understand that beating a drug test when you’re a regular marijuana user is almost impossible.
- These products, while legal, could trigger a positive result as they can create the same byproducts or leave trace amounts of THC in your bloodstream.
- It has more than 100 metabolites, but the most significant ones are 11-OH-THC (11-hydroxy-delta-9-tetrahydrocannabinol) and THCCOOH (11-nor-9-carboxy-delta-9-tetrahydrocannabinol).
- Knowing how long weed stays detectable in a blood test can help individuals navigate these situations more effectively.
- The biggest risk factor for CHS is heavy cannabis use, i.e. daily or multiple instances of use a day for years.
- This is mainly due to the immense belief that marijuana use leads to substantial risk while on the job, whether it’s due to impaired abilities or lack of concentration.

These factors include the frequency and amount of weed consumed, the method of consumption, and individual factors such as metabolism and overall health. While there is no exact timeframe for how long weed stays in your blood, it is generally detectable for a few days to a few weeks. Weed can stay detectable in the bloodstream for up to 12 hours if you’re a regular user, but it’s a sliding scale depending on your body mass, body fat percentage, and frequency of use. Please note that this is just a general guideline and individual results may vary. Other factors, such as the sensitivity of the drug test being used, can also affect the detection timeframe.

How Long Does Weed Stay in Your System? Information on How Long Marijuana Stays in Urine, Blood, Hair & More
THC is stored in fat cells and is slowly released back into your bloodstream over time. 3 This means you could still test positive for THC in a drug test days, weeks, or even months after you last used weed, depending on your usage patterns and personal factors like metabolism. While blood tests can only detect THC within hours after consumption, urine tests can identify THC metabolites days or even weeks later. This prolonged detection period makes urine testing ideal for assessing long-term drug use. Drug tests for cannabis — also known as marijuana, weed, or pot — measure THC and its metabolites. Urine and hair tests have a longer detection window from 1–90 days after the last use.
THC in Drug Tests
- Because THC is broken down pretty quickly into molecules called metabolites, it is detectable in the blood for the shortest amount of time.
- Taking tolerance breaks can help decrease the amount of THC and other cannabinoids and metabolites in your system which can help shrink some of these detection windows.
- However, they did not measure beyond 30 hours to find the last negative result time.
After entering and circulating through the body, some THC will reach hair follicles through small blood vessels where small amounts are deposited into the growing hair. Once the THC is in the hair, it will likely be detectable for years. In fact, hair preserves drug residues so well that scientists can even find evidence of cocaine use in the hair of a 900 year old mummy.9 But, fear not–that is not the normal detection window. Hair follicle drug tests can assess previous drug use for up to 90 days, because as standard they only test the newest 3.9cm of hair.
What factors affect how long THC and its metabolites stay in your system?
Regular cannabis users may have elevated THC levels even after a period of abstinence. There are different types of drug tests that can detect THC in your system. Each test has its own detection window, and how long weed stays in your system depends on the type of test used.
- After smoking, THC runs through the blood and gets stored into fat, where it stays for longer periods of time.
- The process requires opening up the hair cuticles to expose the middle part of the hair follicle where metabolites are stored.
- THC can enter the saliva through exposure to secondhand cannabis smoke.
- For frequent users of heavy doses of cannabis, it can take up to seven days to pass a blood test.
- This THC doesn’t make it into your bloodstream in any significant quantity.
- Today you are going to learn exactly how long THC (including edibles) stays in your system and how to speed up the detox process.
Blood testing for how long does weed stay in the bloodstream cannabis is more useful for catching recent use, like saliva. THC-COOH will only be detectable in the blood for a couple of days after your last use. Saliva tests are more useful for detecting recent use than urine tests, and it’s likely to be detectable (at standard cutoff values) for around 2 days, possibly 3.
