How Long Does 5mg of THC Stay in Your System?

How Long Does 5mg of THC Stay in Your System

The time it takes for 5mg of Tetrahydrocannabinol (THC), the primary active component in cannabis, to leave your body can vary a lot.

Factors such as metabolism, frequency of use, body fat percentage, and hydration can all influence the detection window.

For single-use consumers, the 5mg of THC is detectable in blood for up to 7 days. However, for chronic users, it could linger for several weeks or even more. But note that this is a generalized estimation and every person’s results may change.

Tetrahydrocannabinol (THC) is the compound present in marijuana that causes most of its mind-altering effects.

According to the National Institute on Drug Abuse (NIDA), it acts similarly to the cannabinoid chemicals naturally produced by our bodies. These cannabinoid receptors are mainly found in specific areas of the brain that are linked with various functions like thinking, memory, pleasure, coordination, and time perception.

When THC attaches to these receptors, it activates them, affecting our memory, pleasure, movements, thinking, concentration, coordination, and sensory and time perception, as mentioned by NIDA.

That’s why marijuana can also be used for medicinal purposes, as it’s known to provide relief for conditions like pain, nausea, and glaucoma.

How long do edibles stay in your system?

When you consume THC in edibles, your liver metabolizes it, turning it into a stronger compound that provides a longer-lasting and more intense effect.

After you take it, the effects usually start within 30 minutes to 2 hours, but it can vary depending on your metabolism, body weight, and what you’ve eaten. The effects can stick around for up to 10 hours, with the strongest point usually happening in the first 1 to 3 hours.

When it comes to how long edibles stay in your system, it really depends on a few factors, like your metabolism, how often you use them, your body fat percentage, and how hydrated you are.

For someone who only uses them occasionally, a one-time edible might show up in a blood test for up to 7 days. But for those who use them regularly, it could be detectable for several weeks.

In urine, THC metabolites can be detected for up to 7 days for single-use consumers and potentially up to several weeks for regular users.

How long does 10mg edible stay in your system?

For most of the users, a 10mg edible might be detectable in a blood test for up to 7-14 days. However, for regular users, this can extend to several weeks.

In urine tests, THC metabolites from a 10mg edible can be found for around 7-21 days in occasional users and potentially up to several weeks in chronic users.

Hair tests have the longest detection window, so they can potentially detect THC metabolites for up to 90 days. Remember, these durations are estimations and can vary greatly based on individual physiology and usage patterns.

What does a 5 mg edible do to you?

A 5mg edible is usually considered a good starting point for first-time users or those with a lower tolerance to THC.

The impact may differ depending on factors like metabolism, body weight, and tolerance. But generally, taking 5mg can give you a mild psychoactive effect.

You might experience feelings of relaxation, heightened sensory perception, and subtle changes in thinking. It’s also possible to have a heightened sense of creativity and laughter.

However, edibles can be a bit unpredictable, so the effects might not be the same every time. Always start with a small dose and take it slow which gives your body enough time to process the THC before thinking about having more.

How Edibles Work in the Body?

How Edibles Work in the Body

Edibles go through a unique process in the body that is quite different from smoking or vaping. Here are the key stages:

  • Ingestion: The first stage is ingestion, either by eating or drinking the edible. Unlike smoking where THC directly enters the bloodstream via the lungs, the edible needs to be digested first.
  • Digestion: After ingestion, the edible goes to the stomach where it gets broken down. From there, it travels to the intestines where absorption happens.
  • Metabolization: The absorbed THC is transported to the liver for metabolization. Here, Delta-9 THC, the primary psychoactive compound in cannabis, is converted to 11-hydroxy-THC, a more potent form.
  • Circulation: Once the THC is metabolized (known as 11-hydroxy-THC), it enters your bloodstream. So, you can expect to start feeling the effects of edibles within around 30 minutes to an hour after you consume them.
  • Interaction with Brain: The THC in the blood reaches the brain and attaches to the cannabinoid receptors. This triggers the psychoactive effects associated with THC.
  • Elimination: Over time, the THC is eliminated from the body by the natural metabolic and excretory processes. This is when the effects start to wear off.

Edibles vs. Inhaled Cannabis: Onset and Duration

When you inhale cannabis, it starts right away because the smoke or vapor goes straight into your bloodstream through your lungs. You’ll usually start feeling the most intense effects within 30 minutes to an hour, and they’ll generally wear off within 3 to 4 hours.

On the other hand, edibles have a slower onset, usually between 30 minutes to 2 hours, with the peak effects occurring around 4-12 hours after consumption.

The effects of edibles can actually last for up to 8 or even 12 hours. It all depends on the dose you take and how your body works. But, this longer effect can be great if you’re looking for some long-lasting relief or want to have a sustained experience.

Factors that influence how long THC stays in your system

There are several key factors that influence how long THC stays in your system:

  • Dosage.  The amount of THC in an edible affects how long it stays in your system. Higher doses take longer to metabolize. A 10mg THC edible can last 4-12 hours. Most products have 10mg THC per serving, like one gummy. If you have 20mg THC (two servings), effects can last over 12 hours.
  • Metabolism: Just like with any other substance, your metabolism plays a vital role in how quickly THC is processed and eliminated from your body. If you have a faster metabolism, you’ll generally get rid of THC quicker compared to those with a slower metabolism.
  • Frequency and Quantity of Use: Those who consume cannabis more frequently or in larger quantities will likely find that THC stays in their system for longer periods. This is because THC builds up in the body with repeated use.
  • Body Mass Index (BMI): THC is stored in fat cells. Therefore, people with a higher BMI, especially those with more fat cells, may retain THC for longer periods of time.
  • Hydration: Staying well-hydrated can facilitate the elimination of THC from the body. This doesn’t mean you can flush out THC with water, but proper hydration can support overall metabolic functions.
  • Physical Activity: Regular physical activity, particularly aerobic exercise, can potentially help the body process and eliminate THC more quickly by burning the fat cells where THC is stored.

Detection Window for THC

There are different tests to check for THC in your system. Here are the detection times for edibles:

  • Blood Tests: THC gets eliminated from the blood very quickly, so these tests work best within a few hours to a couple of days after using it. But if you’re a heavy user, it might still show up for about a week.
  • Urine Tests: These are the most common type of drug test. For those who don’t use marijuana often, THC metabolites can usually be detected for up to a week after consumption. If you’re a moderate user, that window might extend to about 3 weeks. But for heavy users, it’s possible to test positive for a month or even longer after your last use.
  • Saliva Tests: THC can be detected in saliva for about 24-48 hours after last use. However, these tests are relatively new and not as common as urine tests.
  • Hair Follicle Tests: This test can find THC in your body for up to 90 days after you use it. However, hair tests are relatively uncommon due to their expense and the fact that they can give positive results from passive exposure to marijuana smoke.

Effects and Duration of Impairment

Since edibles tend to give you a longer “high” compared to smoking cannabis, there are a few effects you should keep in mind.

  • Cognitive Impairment: When you consume THC, whether it’s through edibles or other methods, it can cause temporary cognitive impairment. This means you might have some trouble with memory, attention, and decision-making.
  • Motor Skills: THC can impact your ability to move and coordinate, so it’s highly advised to avoid operating any heavy machinery or driving while using cannabis.
  • Psychoactive Effects: THC causes psychoactive effects like euphoria, altered perception, and relaxation. However, it can also cause paranoia or anxiety, especially in new users or at high doses.
  • Tolerance Buildup: Regular use of THC can cause the development of tolerance, which means that over time, higher doses are needed to achieve the same effects.
  • Dependence and Withdrawal: Regular and frequent use of THC can result in dependence, leading to withdrawal symptoms such as irritability, insomnia, and loss of appetite upon discontinuation.
  • Potential Health Benefits: Despite the potential side effects and risks, THC actually has some health benefits too. It’s used medically to treat conditions like chronic pain, nausea, and glaucoma. It might even help with symptoms of conditions like multiple sclerosis and PTSD. So, it’s not all bad.
  • Long-Term Effects: We still don’t fully understand the long-term effects of THC use, as more research is needed. But, it’s important to be aware that long-term use could potentially cause risks like cognitive impairment and mental health issues.

How can you reduce the duration of THC in your system?

It’s not possible to instantly cleanse the system of THC, but making certain lifestyle changes can definitely help speed up the process.

A balanced diet rich in fiber can help your digestive system eliminate waste more efficiently. It helps you get rid of waste more efficiently, which might just speed up the expulsion of THC

Regular exercise, especially cardio activities like running or cycling, may also help burn fat cells where THC is stored. Hydration is key, too; drinking plenty of water which helps in the removal of toxins from the body.

As THC is fat-soluble and stored in the body’s fat cells, those with a lower body fat percentage or higher metabolism may find that THC leaves their system faster. However, everyone’s body metabolizes THC at a different rate and many factors can affect how long it stays in your system.

Keep in mind that none of these methods guarantee a fast elimination of THC from your body. If you’re aiming to pass a drug test, the most dependable way is to just avoid using it.


In conclusion, the duration that THC remains in your system varies greatly depending on a multitude of factors like metabolism, frequency of use, BMI, hydration status, and physical activity level.

While there are many ways to possibly speed up the elimination process, like living a healthy lifestyle, these methods aren’t guaranteed to make THC removal faster for everyone.

Remember that the most reliable way to pass a drug test is abstinence. Understanding the nuances of THC, its effects, and detection windows can help people create informed decisions about their cannabis use.


Do edibles make eyes red?

Yes, consuming edibles can make your eyes red. This effect is due to THC, the primary psychoactive compound in cannabis, which causes blood vessels in the eyes to expand, increasing blood flow and causing redness.

How quickly do THC levels decrease?

THC levels start to decrease soon after consumption. However, the rate of decrease highly depends on factors like body fat, metabolism, and frequency of use. For infrequent users, THC levels may drop to undetectable levels within a few days. In contrast, for regular users, it could take weeks or even months for THC levels to fall below detectable levels.

What is considered high THC?

Usually, strains with a THC content of about 15-20% are considered high, while those surpassing 20% are often labeled as very high. These strains can give you some strong psychoactive effects and they can also be used for therapeutic purposes, like relieving pain and enhancing your mood.
