How Long Do Nicotine and THC Stay in Your System?

You are interested in how long do THC and nicotine stay in your system? We are here to tell you about that. The timeframe for detection depends on various factors, we’ll explore in-depth in this article.

Keep in mind that individual cases vary, as the metabolites (THC for marijuana and cotinine for nicotine) are detected uniquely by specific tests and exhibit different durations. The presence of THC in your bloodstream varies, and even a single hit can lead to detection, although other weed metabolites may be challenging to go undetected during screenings. Consumption levels, tested chemical structures, and the significance of testing measures also play a role in influencing the detection period.

Whether you need a weed or nicotine test for surgery, health insurance, legal proceedings, employment, or smoking cessation programs, we’ve got you covered. Join us on this informative journey as we answer your most pressing questions about THC and nicotine, including strategies for passing drug tests.

Deciphering Detection Times


According to the National Library of Medicine, nicotine, a component present in tobacco leaves, undergoes metabolism in the liver, with its primary metabolite being cotinine. It is commonly found in blood, saliva, hair, urine, and nails. The amount of cotinine in your system is determined by a few factors, including your exposure to nicotine smoke.

Below are factors influencing the detection of nicotine:

  • Smoking behaviour: The longer nicotine remains in your system is directly proportional to the amount you consume. Therefore, the more frequently you smoke, the greater the concentration of the drug in your system.
  • Age: Age comes with a slower metabolism and fewer body activities that would otherwise speed the metabolism of nicotine.
  •  Type of medications you’re on: Specific drugs will help increase your metabolism rate, while others will reduce it. For instance, antibiotics increase metabolism, which would help eliminate cotinine in your body. Antifungals, however, reduce metabolism in your body and hence slow the flushing out of cotinine.
  • Hormones: Particular hormones like estrogen, produced in abundance in pregnant women, help increase the breakdown of nicotine and the elimination of the metabolite. However, as much as the body can metabolize nicotine, pregnant women are advised against taking nicotine because of birth defects that might result.

Factors Influencing the Detection of THC

THC is the main psychoactive component of cannabis, which has many effects on both animals and humans. The metabolite can be found in biological fluids such as saliva, blood and urine, as well as in hair and nails.

The duration of THC in the system varies based on the following factors:

  • Body fat: THC is stored in fatty tissue. Hence, the more the fat in your system the longer it takes to eliminate the metabolite.
  • Metabolism: The faster the metabolism in your body the faster you’re able to break down cannabis and flush it out of your system.
  • Physical activity: If you’re physically active, you have a higher metabolism than a less active person. Hence, you’re able to eliminate THC faster from your system.
  • Immunity: The main organs involved in the breakdown and elimination of THC are the liver and kidneys. If both of them are underperforming, you’re likely to spend a longer time eliminating THC from your system.

How Long Does THC Stay in the System?

You might ask, “If I smoke once a week, how long till I’m clean?” Well, an occasional cannabis user cannot be compared to a heavy one, speaking of the detection times. Here’s more:

Frequency of use

  1. Once per week: 5 to 7 days detection window
  2. Multiple times a week: 20+ days detection window
  3. Daily/ chronic usage: 30+ days detection window

The above detection times differ, depending on the type of tests carried out. Such tests as hair might uncover THC traces even after 3 months of your last THC intake.

Test Type Detection span Explanation
Saliva 24-72 hours Described as the most crucial test type
Blood 24-48 hours Owing to rapid metabolism
Urine 3-30 days The most basic test type
Hair Up to 90 days Hair takes 90 days to grow 1.5 inches off the scalp, a length that’s mostly required in tests.

How Long Does Nicotine Stay in Your System?

Typically, nicotine and THC have some similar detection windows for light or occasional users. For instance, users who smoke once or a few times a week are likely to have a short detection span of up to 3-4 days. The time is prolonged with heavy users, counting up to 10 days. As cotinine can accumulate in body fat, the more fat you have, the longer it takes to eliminate it.

Following ingestion, liver enzymes metabolize nicotine into cotinine, with the lungs subsequently converting cotinine into cotinine oxide. The resulting metabolite is expelled through urine, saliva, and hair.

However, the difference comes in with factors such as metabolism and the type of metabolite. Cotinine can also be stored in body fluids, which informs its faster breakdown and elimination than THC. It dissolves in water, making a lot of water intake essential for flushing it out, unlike THC which requires detox substances that operate at the cellular level.

Detoxification Strategies

If at one point you may wonder how to pass a drug test as a weed or tobacco smoker, you won’t have to worry much. The type of detox remedy you’d follow would be dependent on factors like the amount of time you have before the test, how frequently you smoke, and how far you’re willing to go with the recommended remedies.

Lifestyle considerations for THC and nicotine elimination:

  • Physical activities: As both metabolites are stored in fatty tissue, increased physical activities will help burn fat. Besides, exercise will increase blood circulation, which will aid in the breakdown and elimination of THC and nicotine.
  • Hydration: Cotinine dissolves in water, so increasing your water intake can reduce the concentration of nicotine and THC in your urine.
  • Diet: Consuming nutritious foods, including fruits and vegetables, can enhance your digestive system and metabolism.

So, the answer to “How long does marijuana stay in your system?” also depends on the type of lifestyle you choose.

Frequently Asked Questions

Is Nicotine a Drug?

Yes! Nicotine is a drug stimulant abundant in tobacco products. Functioning as a stimulant, it speeds up the communication of signals between the body and the brain. Although individuals who use nicotine may develop an addiction, the substance can also be employed as a pharmaceutical to alleviate withdrawal symptoms in those struggling with drug dependency.

How to Pass a Nicotine Test If You Vape?

Decrease your daily nicotine consumption approximately a month before the test and refrain from vaping for two weeks leading up to the examination.

How Long Does it Take for Nicotine to Leave Your System?

Nicotine generally takes 3-4 days to leave your system completely. However, cotinine will take up to 10 days to leave your system, including urine, saliva, and blood.

How Long Does It Take for Marijuana to Leave Your System?

Weed will take 20+ days for occasional users and 30+ days for average users. Since the metabolites are excreted through the hair follicles and nails, you’d need to wait until the required length of hair and nails grows. This is 3 months for 1.5 inches of hair growth off the scalp.

How Long Does Weed Stay in Your Bloodstream?

THC’s presence in your bloodstream varies, with even a single hit leading to detection. The duration depends on factors like consumption levels, tested chemical structures, and the rigour of testing measures.


So far, we hope you have noticed that particular situations determine the detection span for both THC and nicotine. While some people find it easy to get rid of substances in their systems, others might take longer to do that. Such factors include lifestyle, genetics, and the immune system. If you’re up for a better detox experience, you’d need to make a few tweaks to your daily life like incorporating exercise and healthy meals.

The best way to avoid undesired drug test results is responsible drug and substance usage. If you’re on your way to quitting drugs, consider consulting your doctor. Such professional consultations are also important for drug tests.
