How Long Does the Smell of Weed Last in a Room? Tips for Odor Control

Many people enjoy smoking but don’t enjoy the smell that comes with it. This smell can linger in a room for hours, causing awkward and potentially problematic situations. During this time, many wonder if there is a way to get rid of the smell of weed faster. 

If you’ve ever been in one of these situations, keep reading. This article will answer “How long does the smell of weed last in a room?” and what you can do to bring that time down. 

How Long Does the Smell of Weed Last in a Room?

In general, the smell of weed lasts for anywhere between three to five hours. However, this period has a lot of variation to it. Factors relating to the weed itself or the room it is smoked in will impact how long the smell of weed stays around. 

These factors include: 

  • Weed concentration: The concentration of the weed will have a direct impact on how much it smells. Higher concentrations will produce higher concentrations of aroma. This will cause it to stay around for longer periods of time. 
  • Type of weed: Not all weed smells the same. Some strains have a strong and distinct aroma, while others are less prominent. This impacts how they spread around the room and how long the smell sticks around. It also impacts the amount of time it stays in your system. 
  • Consumption method: How you consume weed will change the way it spreads throughout the room. If weed is smoked, it will spread thoroughly around the room and stay around for longer. Meanwhile, if it is vaporized, it will spread less effectively and leave quickly. 
  • Room structure: The nature of the room impacts anything in the air within it. A larger room will have more room for the smell to spread around and, thus, will cause it to be less concentrated. Meanwhile, a room with ventilation will let fresh air in, pushing out the smell of weed.

How to Get Rid of the Smell of Weed Faster

If you are dealing with a room that smells like weed and you want to remove that smell as soon as possible, there are some techniques that you can use. 

Ventilate the Room

One of the few factors impacting how quickly the smell of weed leaves the room that you can control is ventilation. By opening up all of the windows in a room, you can help provide ventilation and completely air the room out. 

If the room doesn’t have windows or generally has poor ventilation, you can try to force some ventilation. You can strategically position fans so that they blow air to or away from the room. You can even add a large window fan to increase the airflow through any windows you can access. 


One of the most obvious ways to eliminate the smell of weed is by cleaning. The smell of weed will cling to everything it touches, so cleaning those things will help get rid of it. 

For surfaces, this means just wiping the surfaces off with something. For fabrics, like curtains or sheets, washing them more thoroughly is necessary. However, in either case, you may be able to provide some relief by using odor-eliminating sprays

Absorb the Odors

Some products out there absorb odors, and some even replace them with their own. Vinegar, activated charcoal, baking soda, and even coffee grounds do this. You can place small bowls of these substances throughout the room, and they will get to work automatically. For powders like baking soda, you can even spread them on a smelly surface, let them sit for a while, and then vacuum them up once they have absorbed all the smells they came into contact with.

Cover Up the Smells

If you want to get rid of a smell, covering it up with another smell is a great option. For this, all you have to do is find something that has a strong smell or fragrance. 

Options here include using air fresheners, oil diffusers, and scented candles. If you use any of these for a while, their smell will overwhelm the room and make it much harder to detect the smell of weed. You can also try to do an activity that produces a strong smell. Often, activities like cooking, especially fragrant dishes, or boiling something fragrant, like boiling cinnamon sticks, will produce smells that will cover up the smell of anything else in the room.

Use Other Consumption Methods

As previously mentioned, smoking will result in more smell than vaping. Meanwhile, taking an edible can result in no smell at all. By switching the way you consume weed, you can significantly reduce its smell. 

Store the Weed Securely 

If you smoke in a room and just leave the weed sitting out, it will continue to add its scent to the room. This is because the terpenes in weed are active whether the plant is being smoked or not. However, you can prevent this by storing it properly. 

The best way to store weed is to use airtight containers. This can be anything from a glass or plastic container that seals securely to a thick plastic bag.
