How Long Does the Smell of Weed Last

The duration for which the smell of weed lingers can vary depending on several factors, including the quality and potency of the cannabis, the method of consumption, and the ventilation in the room. However, while individual experiences may differ, generally, the weed smell lingering in a room lasts for 3 to 5 hours. 

To have a more accurate overview of your situation, refer to the following factors.

Quantity of cannabis consumed: The more cannabis that is smoked, the higher the concentration of the scent in the air, and therefore the longer time the weed smell stays in the space or the fabric. 

Cannabis strain: Certain strains of cannabis have a particularly strong odor that may require extended ventilation and odor treatment to eliminate. For example, Skunk, Cheese, Sour Diesel, Durban Poison, etc. However, there are also strains with more subtle aromas, say,  Northern Lights, Blue Dream, Cherry Blossom, and more. 

Method of consumption: The manner in which cannabis is consumed can significantly impact the lingering smell. Smoking a joint, for example, disperses smoke throughout the room, while using a vaporizer produces minimal odor. Even a single smoked joint can permeate the entire room with its aroma and causes the smell to stay longer in the room. 

Room ventilation: In certain instances, especially if the room is poorly ventilated, the smell of weed can linger for an extended period. It may be detectable for a day or longer, particularly in fabrics, carpets, or other porous materials that can absorb and retain odors.

Now you should have a rough idea about how long does weed smell stay on clothes and in the room. We bet you are wondering how to eliminate or mask the odor, luckily, useful tips are provided in the next part. 

How to Get Rid of Weed Smell

To get rid of or minimize the smell of weed in a room, here are some effective strategies:

Stimulate Ventilation

Open windows or use fans to create airflow, which helps dissipate the smell faster. Consider using an exhaust fan or air purifier to further improve the ventilation system. Whenever possible, smoke in well-ventilated areas or outdoors to minimize the smell indoors.

Odor Absorption

Place bowls of vinegar, coffee grounds, activated charcoal, or baking soda in the room to absorb odors. Alternatively, use odor-absorbing sprays or products specifically designed to neutralize cannabis odors.

Clean Surfaces

Wipe down surfaces, including walls, furniture, and floors, with a mixture of vinegar and water or an appropriate cleaning solution to remove any lingering weed smell. Launder any fabrics, such as curtains, bedding, or clothing, that may have absorbed the smell. Consider using odor-eliminating additives or fabric sprays to freshen up fabrics that cannot be washed.

Use Scented Products

Use scented candles, air fresheners, or essential oil diffusers to mask the odor. Opt for fragrances like citrus, lavender, or mint, which can help neutralize and cover up the smell.

Proper Storage

Store cannabis in airtight containers to prevent the odor from permeating the surroundings. You may also consider using smell-proof bags or jars designed specifically for this purpose.

Smoking Techniques

Choose consumption methods with less smoke and odor, such as using vaporizers, edibles, or tinctures. If smoking, consider using devices equipped with carbon filters or sploofs (devices that filter and mask smoke).

Remember that combining multiple strategies will likely yield the best results. Additionally, maintaining good hygiene in the room will help prevent odors from lingering. 

Why Does the Weed Smell Linger

The distinct smell of weed is primarily attributed to the presence of various chemical compounds, of which the main culprit is the terpenes. Terpenes are aromatic compounds that give cannabis its characteristic scent and can be found in high concentrations within the plant. 

The most common terpene in cannabis is myrcene, which has a musky, earthy scent. It is often associated with the "skunky" aroma of certain strains. Other terpenes such as limonene, pinene, caryophyllene, linalool, and terpinolene also contribute to the unique fragrance of cannabis.

Among these components, caryophyllene is particularly significant as it produces oxidation products that contribute to the authentic smell of cannabis. This distinctive aroma is why police dogs trained to detect drugs can easily identify cannabis.

The diverse range of terpenes and their concentrations in cannabis result in a rich and potent smoke. Consequently, the smell of cannabis can permeate fabrics, wallpaper, furniture, and other objects in an indoor environment. 


After reading this post, you should know how long does the smell of weed last in a room, including the estimated duration, effective solutions to get rid of the odor, and why the weed smell lingers in the surrounding environment. Simply take action by following the solutions above to get rid of the weed smell.
