How Long does Marijuana Stay in Your System After Smoking It Daily?
Smoking marijuana daily increases your risk of cannabis addiction significantly. The more you use the drug, the higher your tolerance, and the longer it’ll take to leave your system. This leads some to ask: If you smoke everyday how long until you are clean?
It depends. You can consider yourself one day sober after your first 24 hours without the drug, and that’s something to be proud of. But, if you want to know how long it’ll show up in a drug test, the answer isn’t the same.
Purpose Healing Center is here to help. We provide effective treatment for marijuana addiction in Arizona. Let’s discuss the nuances of how long it takes for marijuana to leave your system and the role of treatment.
How Long Does Weed Stay in Your System as a Daily Smoker?
Frequent cannabis users will have higher THC levels than someone who smokes less often. If you smoke weed once, a urine test may only detect it for about 3-4 days. However, for daily smokers, a urine test will detect THC for 30 days or more after your last use.
While total THC elimination will take longer for chronic users, regardless of other factors, other things might influence how long THC stays detectable. These include:
- Body fat percentage. Weed is stored in fatty tissues. Those with more body fat may test positive for longer. Conversely, people with lower body fat might experience faster THC clearance.
- Product THC levels. Every marijuana product has a different amount of THC. In addition to how often you use weed, potency can influence the amount of THC in your body.
- While other factors, like declining health, could make you metabolize drugs more slowly, two healthy people can have different drug metabolisms due to genetics alone.
- Liver health. The natural detox process can take longer for people with impaired liver health.
The type of drug test you take can also play a role.
How Long Do Different Drug Testing Methods Detect THC Metabolites?
Some types of drug tests have shorter detection windows than others. THC users may want to know what the different detection windows associated with each test are so that they can test clean from marijuana.
Blood Drug Test
Usually, blood tests detect recent cannabis use for up to about 12 hours. Chronic users have a much longer detection time, with cannabinoids being detected throughout a month of sustained abstinence.
Hair Follicle Test
Hair tests are notorious for having longer detection windows for all types of drugs. A hair test has a THC detection window of up to about 90 days.
Urine Drug Tests
Again, chronic heavy users can have a positive test via urine sample for 30 days or more. “Chronic heavy use” typically refers to those who use weed multiple times per day, daily. If this is not true for you, your THC clearance may vary from days to weeks.
Oral Fluid (Saliva) Tests
Also called an oral drug test or “spit test,” saliva testing is effective for detecting same-day use. Generally, a saliva test will detect weed for up to 24 hours.
How Does the Body Process Marijuana?
THC clearance is a multi-step process. When you smoke or vape weed, THC enters your bloodstream. It binds to fat molecules and is temporarily stored in your body’s tissue and organs. The THC breaks down to various metabolites, which are what show up on a drug test.
Over time, THC is slowly released back into the blood. Finally, it is metabolized by the liver and is eventually excreted by the body through feces and urine.
Some people attempt to speed up the body’s natural detox processes to pass a drug test. Healthy habits, such as drinking enough water and exercising, can support body systems and help you through the detox stage, but they do not help you clear THC rapidly.
Additionally, it is important that you avoid dangerous detox methods. For example, while it’s a popular “tip” shared online, taking large doses of niacin can be life-threatening. Time is the most reliable method for getting THC out of your system.
Workplace Drug Testing for THC
People wondering how long weed stays in their system might also want to pass a drug test for a new or current job. It is always best to be honest. Attempting to tamper with a urine sample or use fake urine for a urine test can have serious consequences, including job loss.
Some employers are more strict than others when it comes to THC use. This can be particularly true in safety-sensitive workplaces, where lapses in judgment or performance could result in harm to yourself or someone else.
THC and Law Enforcement
Some people who are wondering how long a drug test will detect THC for are facing legal battles. There are multiple situations in which someone might get a drug test for THC for legal reasons. For example, you could be on probation or at risk of a driving under the influence charge.
Ceasing cannabis use is the best way to prevent new and worsened consequences resulting from marijuana. That is where addiction treatment comes in.
What to Expect When You Stop Using Weed
Cannabis withdrawal does not come with a high risk of adverse outcomes. However, you may experience symptoms such as the following ailments listed after you stop using weed. Addiction treatment can help you get through the detox process and stay sober.
- Sleep difficulty (e.g., insomnia, disturbing dreams).
- Nervousness or anxiety.
- Decreased appetite or weight loss.
- Depressed mood.
- Restlessness.
- Fever, chills, or sweating.
- Abdominal pain.
- Headaches.
- Tremors.
Most symptoms peak within 2-6 days and end within a week or two. Sleep disturbance can continue for several weeks or longer. Cannabis withdrawal symptoms will go away as your body adjusts to living without the drug.
Addressing the Underlying Causes of Daily Cannabis Use
You may have had certain concerns, like trouble sleeping or anxiety, before you started using marijuana. A substantial portion of people with cannabis use disorder have at least one other mental health condition. Notably, weed can contribute to worsened mental health.
Some people feel that weed is a form of self-medication, especially before cannabis use disorder starts to affect their life negatively. This can make it hard to stop. Treating the underlying causes of cannabis use disorder is essential.
Purpose Healing Center addresses co-occurring disorders that pair with cannabis use. Our dual-diagnosis approach supports whole-person recovery from cannabis addiction and other forms of substance abuse.
Treatment for Chronic Cannabis Use
Treatment for chronic cannabis use can help you get and stay off marijuana. At Purpose Healing Center, we’re here to help you not just through the initial detox stages, but with long-term recovery. Marijuana addiction recovery may involve:
Individual Therapy and Groups
Our marijuana addiction treatment programs involve regular (at least once-weekly) individual therapy sessions and multiple groups per day. In these sessions, providers may use treatments such as behavioral, motivational, and experiential therapies, 12-step, and trauma-focused therapies.
Family Therapy Sessions
Family therapy sessions are recommended for those in addiction treatment when possible. These sessions do not need to include only immediate family members. Any loved ones can get involved. Couples counseling is also available.
Inpatient Addiction Treatment
Inpatient marijuana addiction treatment involves living on-site at Purpose Healing Center. This program provides 24/7 supervision in a drug and alcohol-free environment, which can help clients avoid triggers for cannabis use during the early stages of recovery.
You will follow a highly structured schedule, which will help you build healthy habits while getting the most intensive therapy for addiction. Most clients stay in inpatient rehab for marijuana for about 30-60 days.
Outpatient Addiction Treatment
We offer multiple levels of outpatient care for marijuana abuse. You might start treatment in an outpatient environment, or you might transition into one of the following programs after completing inpatient drug rehab.
Our partial hospitalization program (PHP) provides the most intensive therapy available in an outpatient environment. Clients in this program spend most of the day at our center for therapy sessions, but sleep and live at home.
The intensive outpatient program (IOP) at Purpose is the next step down from PHP. Clients in IOP for marijuana addiction participate in fewer therapy hours per week, which makes it possible to balance obligations like work with treatment.
Support Groups for Marijuana Abuse
Support groups like Marijuana Anonymous (MA) are free resources for people with a desire to stop using marijuana. MA is a 12-step group, but non-12-step alternatives are available, too. For example, SMART Recovery.
Aftercare and Relapse Prevention
Aftercare planning is an essential part of treatment. Before your time in treatment at Purpose comes to an end, we will discuss your next steps and work with you to create a relapse prevention plan.

FAQs About How Long it Takes Daily Smokers to Test Clean
How long does it take for weed smoke to leave your body?
It depends. Occasional users eliminate THC faster. If you smoke daily, cannabis metabolites will remain detectable for longer, and can stay in your body for a month or more in some cases.
Can you get a positive drug test from secondhand marijuana smoke?
It is possible, but highly unlikely, that you will get a positive drug test result from secondhand marijuana smoke. The risk typically applies only under extreme, specific conditions, such as prolonged exposure to secondhand smoke.
