How to Get Rid of Cannabis Smells & Marijuana Smells

Problems caused by cannabis smells

Cannabis odours can be a real problem. 

Especially in terraced houses and flats, where smells infiltrate other rooms and houses. Aside from legal or rental issues, some potential problems are:

A negative impact on others. If you’re not a smoker, the strong, distinct smell of cannabis can be unpleasant. The smell can linger in shared spaces and seep through walls. It can disrupt other people’s sleep and work, creating frustration for those affected​. 

The smell can create social tension and conflict. 😠 Complaints about cannabis odours often lead to tension between neighbours, particularly if the person feels uncomfortable addressing the issue directly. Parents can become angry that their children are having to smell it, even if it's from passing a house in the street. Complaints can lead to defensive reactions, particularly if landlords or property managers get involved.

The smell gets absorbed into fabrics and furnishings. Cannabis odours cling to fabrics, carpets, and furniture, making it challenging to remove the smell entirely without extensive cleaning. For homeowners or renters, this can lead to costly cleaning efforts and even affect property value if odours become deeply embedded and difficult to get rid of.

Most common ways to get rid of cannabis smells

To tackle cannabis odours, several methods are commonly used, each with varying degrees of effectiveness depending on the size of the room, ventilation, and the strength of the smell. 

Common ways to get rid of cannabis smells are:

• Opening windows and doors: 🪟 Ventilation is the simplest way to reduce cannabis smells, especially the doors or windows are open on opposite sides of the house. Although, as we’ve said, this can cause tension and complaints from neighbours and passersby, and potental legal or rental issues. ​
• Air purifiers with carbon filters: High-quality air purifiers with activated carbon filters, like the Smell Away® Odour Neutraliser, are effective at capturing smoke particles and odour molecules. 
• Odour neutralisers: Products with activated charcoal, like the Smell Away®, or baking soda, and odour-eliminating sprays neutralise smells rather than mask them. Activated charcoal absorbs odours from the air and works best in enclosed spaces. Baking soda, placed in open containers, can also help absorb odours but is most effective for smaller spaces like cupboards​.
• Essential oils and scented candles: 🕯️ Essential oils (like lavender or citrus) and scented candles mask the smell of cannabis but don't eliminate it. They are best used in combination with other methods, such as ventilation or odour-neutralising products, to improve the overall smell of a space.
• Ozone generators: Although not recommended for occupied areas due to potential health risks, ozone generators are sometimes used to neutralise strong odours. These devices release ozone, which can react with odour-causing particles in the air. However, they should be used with caution and only in empty rooms, as ozone can be harmful to breathe in high concentrations​.

Odour masking vs. neutralising

Odour neutralisers work better than air fresheners, which only mask the smell temporarily. For lasting removal, products designed to break down odour molecules, such as activated charcoal, are effective choices.

This is why the Smell Away® has been designed with an activated carbon filter (which is the same as activated charcoal filter). The filter lasts 1-2 years, depending on usage.

Each method has its strengths, but a combination — such as ventilation and the Smell Away® Odour Neutraliser — is most effective for consistently controlling cannabis smells.

Use the Smell Away® to get rid of cannabis smells. You can keep the windows closed to AND get rid of the smell

The Smell Away® Odour Neutraliser targets cannabis smells by using active ingredients designed to neutralise, rather than mask, the odour.

The Smell Away® works by breaking down odour-causing molecules on a chemical level. It uses an activated carbon, odour-neutralising filter that specifically addresses persistent smells like cannabis smoke.

For the best results, place the Smell Away® near to the source of the cannabis smell, switch it on before the smell gets any stronger in the room, and leave it on until you can notice it’s getting a hold of the smell.

If the cannabis smell has been absorbed into furniture and carpets, it will take some time for all of the smells to be released out of the fabrics and for the Smell Away® to capture all of that nastiness. But persevere and the Smell Away® will continue to neutralise all of those odours. 

Get rid of smells while keeping your windows closed. It's good for your neighbours too.

In the UK, a common issue with cannabis odours drifting outside of the building onto the street, or from one property to another, has led to various tensions and even legal actions.

In shared or multi-family housing, residents report frustrations over pungent cannabis smells invading their homes through walls, ventilation systems, and open windows. In some cases, neighbours are left with no option but to speak directly with the individual, only to be met with resistance.

For instance, one resident in London found themselves repeatedly affected by the smell from a neighbour’s cannabis use, which led them to contact both the property manager and local council for help. Unfortunately, due to the limitations on council action regarding personal cannabis use in private spaces, the resident was advised to take the matter up with the neighbour directly or consider a private civil complaint, options which often add strain to neighbour relations​.
