How Long Does THC Stay in the Blood?

The primary psychoactive compound in cannabis is tetrahydrocannabinol or THC. New or frequent users of marijuana must know the answer to how long does THC stay in the blood. The reason is that this knowledge can help them stay negative in cannabis drug tests. The common drug testing method can detect THC metabolites for up to 1-2 days after use for occasional users. Meanwhile, they remain identifiable in the blood for up to a week or longer for heavy users.

THC remains in the blood for varying lengths of time. Also, other types of drug test options can detect THC for different durations. For example, urine tests identify THC for up to 30 days, hair tests for up to 90 days or longer, and saliva tests for up to 24 hours. Nevertheless, many prefer blood tests to oral fluid, hair follicle, and urine testing. Thus, the article will present the factors that influence the duration of THC in the blood.

How Long Does THC Stay in the Blood Is Influenced by the Frequency of Use

The frequency of use influences how long does THC stay in the blood. The body metabolises THC and eliminates it through various processes. Generally, drug screening can detect THC in the blood for a few hours up to a few days after use. However, how often a person uses cannabis significantly affects the duration.

When an individual takes marijuana or consumes cannabis products, the bloodstream quickly absorbs THC. Then, it is distributed throughout the body. It undergoes metabolism in the liver, resulting in the formation of various metabolites. The amount of time it takes for the body to eliminate THC and its metabolites can vary depending on the frequency of cannabis use.

Typically, light users can eliminate THC from the blood within a few hours to a couple of days. However, chronic users of medical marijuana or regular recreational users may have detectable levels of THC in their blood for much lengthier periods. Chronic cannabis users may still have traces of THC in their blood even weeks after their last use.

Dosage Consumed

• 5mg: Moderate users, those with low THC tolerance, or one-time users typically use this low dose. It may produce mild relaxation and subtle mood uplifts.
• 10mg: A commonly advisable starting dose for regular cannabis users. It can provide more relaxing effects and slight increases in euphoria.
• 15-20mg: This dose can result in stronger euphoric effects and potential perception alterations. It may also enhance creativity and sociability.
• 25-30mg: The higher dose can induce a powerful state of relaxation. Moreover, it can potentially impair cognitive functions.
• 40mg and above: Very potent doses that can lead to intense psychoactive effects, impaired memory, and the potential for paranoia.

How Long Does THC Stay in the Blood Is Affected by the Method of Consumption

The consumption method affects how long does THC stay in the blood. When people smoke marijuana, the body rapidly absorbs THC into the bloodstream through the lungs. As a result, they feel the effects almost immediately. However, the detection duration is relatively short. On average, drug screens can identify THC in blood for up to 24-48 hours after smoking.

Meanwhile, when individuals ingest cannabis, such as through edibles or capsules, the onset of effects is delayed. The reason is that the body metabolises THC in the liver before entering the bloodstream. Subsequently, this results in slower releases of the chemical. Then, this extends the duration for which THC remains detectable in the blood, which is up to 1-7 days after ingestion.

Alternatively, when users consume THC through topicals or transdermal patches, the chemical does not directly enter the bloodstream. Instead, the body absorbs it through the skin. This is where it interacts with localised cannabinoid receptors. THC typically does not remain detectable in the blood through this method, as the chemical does not enter systemic circulation. However, it is identifiable in other bodily fluids, such as saliva or urine samples.

Understanding How the Body Processes THC

When THC enters the body, it is rapidly absorbed into the bloodstream through the lungs or the digestive system. From there, it travels to the brain and other organs, impacting various systems in the body. Once in the bloodstream, THC binds to cannabinoid receptors, specifically CB1 receptors. The interaction results in the psychoactive components of the drug.

After the initial impact of THC on the brain, the liver metabolises it. It breaks down THC into various metabolites. Then, the body further breaks down the marijuana metabolites before eliminating them through bodily fluids. Nevertheless, factors such as individual metabolism can affect how long it stays.

How Long Does THC Stay in the Blood Is Influenced by Individual Differences

Individual factors or differences play a significant role in determining how long does THC stay in the blood. Some people metabolise THC more quickly than others. This is due to genetic variations in liver enzymes responsible for the breakdown of substances. Therefore, their genetic makeup impacts how long THC concentration remains detectable.

For instance, the cytochrome P450 (CYP) enzymes are responsible for metabolising THC in the liver. Variations in the genes that code for these enzymes can result in different metabolism rates. Some individuals may have gene variants that make them fast metabolisers. Hence, they break down THC quickly and eliminate it from their system faster. Meanwhile, slow metabolisers may have gene variants that cause THC to stay in their blood for lengthier periods of time.

Also, Body Mass Index (BMI) and hydration levels can influence how long THC remains identifiable. Regular users with a higher BMI may store THC in fatty tissues or cells longer, leading to extended periods or detection windows. Drinking lots of water plays a role in flushing out THC from the body more efficiently, potentially reducing the time it stays in the blood.

Understanding Metabolism

After consumption, the body absorbs THC into the bloodstream quickly through the gastrointestinal tract. It reaches peak concentrations within the first hour. Metabolism of THC primarily occurs in the liver, where it undergoes enzymatic breakdown and transformation into various metabolites.

The metabolism of THC involves two main pathways: oxidation and conjugation. Oxidation mainly occurs through the action of enzymes known as cytochrome P450. It converts THC into its primary metabolite, 11-hydroxy-THC. The body metabolises it further through secondary oxidation and conjugation reactions, forming other metabolites like THC-COOH, the primary inactive metabolite. It is responsible for the prolonged detection of THC in drug abuse tests.

Conclusion

Various factors affect how long does THC stay in the blood. One of these is the frequency of consumption. Chronic or daily users are likely to have higher THC levels in their bloodstream, resulting in a longer detection window. Meanwhile, infrequent cannabis users may have lower levels, leading to a shorter detection period. Moreover, different yet common methods of consumption affect the duration. Inhalation results in shorter detection times. In contrast, edible consumption leads to extended periods.

Furthermore, individual factors can influence how long THC stays detectable in the bloodstream. People with faster metabolisms may have a shorter detection window, while those with slower metabolisms may have THC lingering in their system for a longer period of time. BMI and hydration levels also impact the window of time blood form of drug testing can detect THC. Ultimately, understanding how long THC remains detectable in the blood is crucial for those undergoing drug tests.
