If I smoke once a Week, How Long Till I’m Clean?
If you smoke once a week, THC is likely to stay in your system for about 1 to 3 days. However, this can vary depending on your metabolism and other factors, too, like how much THC was in the weed you smoked and your body fat percentage. If you smoke once a week, you should wait for a week before taking a test. 1
How Long Does Marijuana Stay in the System?
For occasional weed smokers, it may take about 3-7 days for THC to be eliminated. With regular users, this may even take as long as 30 days to clear the system. Heavy and chronic use takes about 90 days to fully clear THC.
How Long Does Weed Stay in the Blood?
THC stays in the blood for the shortest window compared to other methods. For those who smoke once a week, THC may be detectable for up to 1-3 days. 2
How Long Does Weed Stay in Urine?
One of the most common methods of detecting weed is through urine testing. If you smoke once a week, THC may be detectable for 2-3 days. 1
How Long Does Weed Stay in Your Salivary Glands?

How Long Does Pot Stay in the Hair?
Hair follicle testing is used to determine evidence of long-term use. Even if you smoke once a week, marijuana can be detected in the system for up to 90 days.
Does THC Store in Fat Cells? What Does That Mean For a Drug Test?
THC is stored in fat cells, which is why you may test positive for a drug test well after quitting smoking. Marijuana breaks down to yield tetrahydrocannabinol (THC), which is the main active ingredient responsible for causing a high. Once THC enters your body, it is distributed to various tissues, including fat cells. People with more body fat may hold onto THC longer than those who are leaner.
Factors that influence the clearance of THC
- Body Metabolism
- Body Fat Percentage
- Diet and Hydration Status
- Frequency of smoking
- Mode of consumption
Information CornerWhat is the difference between cannabis, weed, hemp, and hash?Cannabis is the name of the plant. Weed, marijuana, and hash (hashish) refer to various products that are made from the plant. These terms are often used interchangeably. |
Can a Weed Detox Kit or Juice Cleanse Help Clear THC Faster?
Despite what claims say, both weed detox kits and cleanses are ineffective in eliminating THC. Cleanses and cannabis detox cannot shorten the time THC stays in the body. Your body will naturally clear the body through its metabolic pathway. Companies making detox drinks are not transparent about what they add to their kits. Store-bought detoxes may be loaded with unknown ingredients that may pose harm to overall health.

Best Way to Get Weed Out of Your System Faster
Now that we have established that detox drinks may not work to help you pass a drug test or flush weed out of your system, what is the way forward?
The best way to flush weed out of your system is through a medical THC detox. 5
Medical detox typically involves:
- Clinical monitoring of withdrawal symptoms
- Supportive medications to reduce cravings and discomfort
- Nutritional support and hydration
- Ongoing mental health and addiction treatment
Why Detoxing From Weed is Not Just About Flushing It Out
Marijuana contains THC (tetrahydrocannabinol), a fat-soluble compound that can stay in your body for days to weeks, depending on your metabolism, body fat, frequency of use, and potency of the drug. While some may not experience withdrawal, chronic users often report marijuana withdrawal symptoms such as:
- Anxiety or irritability
- Insomnia or vivid dreams
- Headaches
- Loss of appetite
- Cravings
- Fatal risk of overdose
These symptoms can make quitting extremely difficult without professional help. This is why marijuana medical detox is the safest and most effective way to manage withdrawal symptoms and achieve a clean start.
Myths Vs. Facts About Weed Detox
Detox pills for weed or THC detox drinks, do they actually work? We have asked Jessica Plonchak (Executive Clinical Director) at ChoicePoint to provide more clarity on myths vs. facts on marijuana detox:
| Myth | Fact |
| You can flush THC out of your body in 24 hours using detox drinks. | THC can remain in the body for days to weeks. No detox drink can remove it instantly or reliably. |
| Sweating through exercise or saunas rapidly clears THC. | Exercise may help long-term, but sudden attempts can release more THC into your bloodstream temporarily. |
| Drinking excessive water before a test will guarantee a pass. | Overhydration can dilute urine but may also result in a failed or flagged drug test. |
| Natural remedies like cranberry juice or vinegar cleanse the system. | These remedies have no scientific backing and do not significantly speed up detoxification. |
| Marijuana withdrawal is not real, so you do not need help to quit. | Long-term users can experience real and difficult withdrawal symptoms that can be treated with medical care. |

How can I get away with a drug test?If you expect to be tested any time soon, you have to stop and stay off the drug for some time. Do not attempt to evade a drug test by masking your urine or submitting someone else’s. Specimen validity tests can detect if urine has been adulterated, and several states have made drug test fraud a punishable offense.

FAQs
1. How long does it take to get clean if I smoke once a week?
For frequent users, THC can be detectable for up to a week in blood and saliva. In hair, it can be up to 90 days.
2. How long will 3 puffs of a joint stay in your system?
Even if you’ve taken a couple of puffs, THC might stay in your system for 1 to 3 days. As this is a light concentration, THC will be processed more quickly than if you had smoked a whole joint.
3. Can you sweat out THC through exercise?
Rapid weight loss or exercise can make you test positive for longer. Weed and its metabolites are fat-soluble, meaning that they are stored in fat, so when fat breaks down, they get released.
4. Can cranberry juice clear THC?
Since THC is bound to the fat cells, no amount of juice “flushes” can wash out cannabis.
5. Can you fail a drug test from secondhand smoke?
It is extremely unlikely that you’ll fail a drug test because of passive smoking. However, a drug test can be positive because of secondhand smoke.
6. Are home drug screens accurate?
No at-home drug tests are 100% reliable. A professional lab test is a better option to rule out exposure to marijuana.
7. What if I’m taking marijuana for medical reasons?
If you smoke for medical purposes, some states will let you bypass the test through a medical prescription. Check out your state’s laws to see if Marijuana is legal.
