How to Overcome a Cannabis High? Duration, Effects & Proven Remedies

Feb 21, 2025

Cannabis is one of the most commonly used substances worldwide, and with increasing legalization, many users are concerned about how long weed stays in their system. Whether for employment drug tests, legal reasons, or personal curiosity, understanding the duration THC (tetrahydrocannabinol) remains detectable is crucial.

Various factors affect the retention of weed in the body, including metabolism, frequency of use, and the type of drug test conducted. In this blog, we will dive deep into the science behind cannabis detection, types of drug tests, and tips for clearing it from your system faster.

How Long Does THC Stay in Your Body?

How Long Cannabis High Stays on your body?

THC, the psychoactive compound in cannabis, is stored in fat cells and gradually eliminated through urine, sweat, and feces. The length of time THC stays in the body depends on several factors, such as:

Metabolism: Faster metabolisms clear THC quicker.

Frequency of Use: Occasional users eliminate THC faster than daily users.

Body Fat Percentage: Since THC is fat-soluble, individuals with higher body fat retain it longer.

Hydration & Diet: Dehydration can slow THC elimination, whereas drinking water and a balanced diet help flush it out faster.

Cannabis Detection Time by Test Type

Cannabis effect duration

Different drug tests have varying detection windows, as each test targets different THC metabolites or components. The method used determines how far back cannabis use can be detected. Here’s a breakdown of how long THC remains detectable based on the type of test:

1. Urine Test

Urine testing is the most common and widely used method for detecting cannabis due to its affordability, reliability, and ease of administration. It primarily detects THC-COOH, a metabolite of THC that lingers in the body long after the effects have worn off. The detection time varies based on usage frequency:

Occasional users (1-3 times per week): THC metabolites are typically detectable for 3-5 days.

Moderate users (4-5 times per week): Detection can extend up to 7-10 days.

Frequent users (daily): THC can be detected for up to 10-30 days.

Heavy users (multiple times daily): Detection may last up to 90 days in extreme cases, especially for individuals with high body fat.

2. Blood Test

Blood tests detect active THC in the system, making them useful for identifying recent cannabis use. Unlike urine tests, which detect metabolites, blood tests measure the actual presence of THC, meaning their detection window is much shorter:

Occasional users: Detectable for 1-2 days after use.

Regular users: THC may remain in the bloodstream for up to 3-7 days.

Chronic users: Heavy, long-term users may test positive for up to 25 days, especially if their body has accumulated high THC levels.

Impairment testing: Since blood tests measure active THC, they are commonly used in DUI (driving under the influence) cases to determine impairment levels.

3. Saliva Test

Saliva tests are often used for roadside and workplace drug screenings, as they can quickly detect recent cannabis consumption. These tests identify the presence of THC rather than its metabolites, leading to a shorter detection time:

Occasional users: Can test positive for up to 24-48 hours after last use.

Frequent users: Detection may extend up to 72 hours.

Heavy users: Some reports suggest that chronic users could test positive for up to a week, but this is less common.

Legal implications: Saliva testing is often used in places where zero-tolerance policies for impaired driving exist.

4. Hair Follicle Test

Hair follicle testing has the longest detection window and is often used for forensic and employment screenings. These tests can reveal cannabis use from months prior, as THC metabolites get trapped in hair shafts and grow out over time:

All users (even a single-use): Detectable for up to 90 days.

Detection method: A small sample of hair (usually 1.5 inches from the scalp) is analyzed to determine past cannabis consumption.

Limitations: While effective at long-term detection, hair follicle tests are less reliable for detecting very recent cannabis use (within the past few days).

Factors That Influence THC Retention

Factors to consider before using cannabis

The time it takes for THC to leave the body is not the same for everyone. Many variables impact how long cannabis remains detectable, from individual body composition to lifestyle habits. Understanding these factors can help explain why two people who consume the same amount of cannabis may have different detection times in drug tests.

1. Frequency of Use

First-time users clear THC faster than chronic users.

Daily consumers accumulate THC metabolites, leading to longer detection times.

2. Body Fat and Hydration

Higher body fat percentage stores THC for extended periods.

Drinking more water and staying hydrated helps flush out metabolites.

3. Metabolism and Activity Level

Active individuals with higher metabolisms eliminate THC quicker.

Exercise can temporarily increase THC release into the bloodstream but doesn’t drastically speed up elimination.

4. Consumption Method

Smoking/Vaping: THC enters the bloodstream quickly and clears out faster.

Edibles: Metabolized through the liver, leading to longer retention.

Dabbing/Concentrates: Higher THC potency means longer detection times.

How to Speed Up Cannabis THC Elimination

How to get rid off cannabis effects quickly

1. Hydration and Detox Drinks

Drinking plenty of water, herbal teas, and electrolyte-rich drinks can help flush THC metabolites. However, excessive water intake can lead to diluted urine, which may raise suspicion during a drug test.

2. Exercise and Sweating

Engaging in cardio workouts and sauna sessions may assist in eliminating THC faster by burning fat where THC is stored. However, exercising too close to a test can temporarily increase THC levels in the blood.

3. Healthy Diet

Eating fiber-rich foods, leafy greens, and lean proteins can enhance metabolism and detoxification. Avoiding high-fat meals may prevent further THC storage in fat cells.

4. Abstinence

The only guaranteed way to clear THC is to stop consuming cannabis and allow time for natural elimination. The detox process varies per individual but is the most effective method.

Can You Cheat a Drug Test?

Cannabis drug testing method

Many myths surround passing drug tests, but most are unreliable or risky:

Detox Products: Some claim to speed up THC removal, but results vary. Some products may also contain ingredients that can be flagged by labs.

Synthetic Urine: Illegal in many places and detectable by advanced tests that check for temperature, creatinine levels, and other markers.

Dilution Methods: Drinking excessive water may dilute urine, but labs can flag diluted samples and require a retest or reject the results.

Home Remedies: Some suggest cranberry juice, vinegar, or niacin to flush THC, but there is no scientific evidence that these methods work effectively.

The length of time weed stays in your system varies based on personal factors and consumption habits. Understanding drug test detection windows and how to naturally detox can help users prepare for screenings. While some methods may slightly speed up the process, the most reliable way to pass a drug test is abstinence. If you are a medical marijuana user, discussing your situation with your employer or legal authority may be an option.
