How Long Does the Smell of Weed Last?
Weed is aromatic, without a doubt — cannabis is infamous for the strength and variety of its scents. Typically, the more pungent the aroma, the higher quality of cannabis. Many consumers “follow their noses” to find their favorite cultivars. While we love the delicious smell of each strain’s terpene bouquet, sometimes cannabis odors must be kept to a minimum.
Where Does Cannabis’ Smell Come From?
Cannabis’ signature scent comes from compounds inside the plants’ trichomes called terpenes , or terpenoids. Terpenes are organic, aromatic compounds that provide the aroma and flavor in cannabis and a variety of other organisms, including plants. Each cultivar has its own unique arrangement of terpenes, and there are more than 200 terpenes in cannabis alone. This is why different cultivars can deliver citrus, pine, coffee, spicy, diesel, herbal and tropical flavors — they each have distinct terpene profiles.
What Affects the Strength of Weed’s Smell?
Multiple environmental factors contribute to how powerful a cultivar’s odor is when you first open the cap. Are you smoking your flower indoors or outdoors? Is your AC running, and how good is the airflow in the room? Are your windows open? All of these play a role in how long strong your weed smells throughout the smoking problem.
Using different consumption gear can also minimize the strength of your weed’s smell. Glassware like a bowl or, even better, a bong produces less stink than a constantly burning joint or blunt. Vapes are even better, as they can burn cannabis at lower temperatures that reduce the smell. However, it’s important to keep your gear clean , as a dirty bong or vape can sometimes give off stronger aromas with the buildup of plant matter.
Storage also plays a huge role in the strength of your weed’s smell. Keep your flower in dark, glass jars in a cool, dark space—not only will this put a literal lid on your flowers’ smell, but proper storage also minimizes exposure to light and air degradation. When properly stored, well-grown and well-cured cannabis can maintain its terpenes and cannabinoids up to two years.
How Do I Minimize the Smell of Weed?
After a particularly strong-smelling smoke session, you may find yourself needing to minimize the odorous evidence. Helpful deodorizers like Febreeze or scented deodorant will mask the smell, though not eliminate it entirely. Burning incense or scented candles can also keep the smell at bay.
In real-time, blowing smoke out of an open window or into an air conditioner vent will help circulate the cannabis smell out of a room. You can also make a blow tube, sometimes called a sploof, to catch the smoke. A sploof is a tube of cardboard with a dryer sheet wrapped around one end that will “catch” and diffuse the smell of weed.
Finally, if you need to smoke in stealth mode, make sure to wash any clothes that smell like weed to completely remove the scent. When you burn cannabis, you release additional compounds into the air, including ones that stick to your hair, skin, clothing, and other surfaces. Even if you can’t smell it (thanks to the interesting phenomenon called olfactory adaptation , when aromatic molecules bind to the receptors in our noses and prevent us from detecting a specific odor), it’s worth it to do a cursory rinsing off of the evidence.

How Long Does Weed (Marijuana) Stay in Your System?
It varies according to dose
Weed, also known as marijuana or cannabis, is usually detectable in bodily fluids for 1 to 30 days after last use. As with other drugs, it may be detectable in hair for several months.
Weed detection windows depend on how much you smoke or ingest, as well as how often. In general, higher doses and more frequent use are associated with longer detection times.
For daily users, cannabis may be detectable for several months after last use. The longest-reported detection times are more than 90 days.
Read on to find out the detection windows for cannabis in urine, blood, saliva, hair, and more.
Drug tests measure weed and its by-products, or metabolites. These metabolites remain in your system long after weed’s effects have worn off.
According to Mayo Clinic Proceedings, weed is detectable in urine for the following amounts of time after last use:
- Occasional users (up to three times a week): 3 days
- Moderate users (four times a week): 5 to 7 days
- Chronic users (daily): 10 to 15 days
- Chronic heavy users (multiple times a day): more than 30 days
Cannabis metabolites are fat-soluble, which means they bind to fat molecules in your body. As a result, it can take some time for them to leave your system.
According to an article in Therapeutic Drug Monitoring, weed is typically detectable in the blood for 1 to 2 days. However, in some cases, it’s been detected after 25 days. Chronic heavy use increases the length of time that it can be detected.
Weed is detectable in the bloodstream within seconds of inhalation. It’s distributed to the tissues. Some of it is reabsorbed in the blood and broken down. Its metabolites may remain in the bloodstream for days.
Blood testing may be used in laboratory settings or to indicate recent use of weed.
According to a 2014 review on cannabinoids in oral fluid, weed is detectable in saliva for the following amounts of time after last use:
- Occasional users: 1 to 3 days
- Chronic users: 1 to 29 days
Weed can enter the saliva through smoking and exposure to smoke. However, its metabolites are only present in saliva when weed has been smoked or ingested.
In jurisdictions where weed is legal, oral fluid may be used for roadside testing.
Hair follicle tests assess drug use for up to 90 days . After use, weed reaches the hair follicles via small blood vessels. Trace amounts may remain in the hair.
Since hair grows approximately 0.5 inches per month, a 1.5-inch hair segment taken close to the scalp can provide a window of weed use for the past three months.
The active ingredient in weed is a chemical substance called THC, which stands for delta-9-tetrahydrocannabinol. THC that enters your body is absorbed into the bloodstream.
Some THC is temporarily stored in organs and fatty tissues. In the kidneys, THC can be reabsorbed into the bloodstream.
THC is broken down in the liver. It has more than 80 metabolites, but the most significant ones are 11-OH-THC (11-hydroxy-delta-9-tetrahydrocannabinol) and THCCOOH (11-nor-9-carboxy-delta-9-tetrahydrocannabinol).
Drug tests look for these metabolites, which stay in your body longer than THC. Eventually, THC and its metabolites are excreted in urine and stool.
A number of factors affect how long weed stays in your system. Some of these factors, such as your age, gender, and body mass index (BMI), aren’t related to the drug itself, but to how your body processes and metabolizes the drug.
Other factors are related to weed and how you use it. This includes how much you take (dose) and how often (frequency). Higher doses and more frequent use tend to increase the amount of time it takes to eliminate weed from your system.
More potent weed, which is higher in THC, may also stay in your system for longer. Weed that’s ingested may also remain in your system slightly longer than weed that’s smoked.
There isn’t much you can do to speed up the amount of time it takes for weed to leave your system.
Once it’s entered your system, your body needs time to break it down. Exercising, eating healthy, and staying hydrated may help, but not drastically.
There are a number of weed detox remedies and kits available on the internet. Many require drinking a lot of water to dilute your urine, and then using herbal supplements such as creatinine or vitamin B-12 to mask the dilution.
These kits don’t work reliably.
Weed’s effects appear quickly, usually within 15 to 30 minutes after smoking. It can take one or two hours to feel weed’s effects when it’s ingested.
Weed’s active ingredients produce a short-term “high.” Common effects include:
- sense of well-being
- sense of relaxation
- feeling that time is slowing down
- giggling or chattiness
- altered sensory perception
Other short-term effects include:
- inability to focus
- increased appetite
- coordination problems
- rapid heart rate
- dry mouth and eyes
- feeling sick or faint
- anxiety or paranoia
In rare cases, high doses of weed can cause hallucinations, delusions, and psychosis.
Smoking or ingesting weed on a regular basis can have additional effects on your mind and body. You might be at an increased risk of developing:
- cognitive impairments
- memory impairments
- learning impairments
- cardiovascular diseases, such as heart disease and stroke
- respiratory illnesses, such as bronchitis and lung infections
- mood disorders, such as depression and anxiety
- hallucinations and psychosis
If you use weed while you’re pregnant or breastfeeding, there’s a greater chance that your baby will have birth defects or problems with brain development.
Weed’s short-term effects start to taper off after one to three hours. Some effects, like memory problems or trouble sleeping, can last a few days.
Researchers don’t know how long the effects of chronic use last. Long-term effects can last days, weeks, or months after weed use has ended. Some effects may be permanent.
Weed may stay in your system anywhere from several days to several months after last use. Detection windows depend on the drug test used and other factors, such as whether you smoke or ingest weed on a regular basis.
Weed is detectable in bodily fluids for up to 30 days after last use. For daily users, weed may be detectable for several months after last use. The longest-reported detection times are more than 90 days. Here’s how long it’s detectable via each type of drug test, whether you can metabolize it faster, and more.
