Acheter un purificateur d'air pour le cannabis

La marijuana est l’une des drogues les plus consommées dans le monde. Utilisé par tous les segments démographiques, sa popularité augmente significativement. En France, 44,8 % de la population âgée de 18 à 64 ans avait consommé du cannabis au moins une fois au cours de sa vie, contre 12,7 % en 19921. Avec sa forte odeur et les effets négatifs sur la santé dus à la fumée secondaire, le cannabis est souvent une nuisance pour les colocataires et les voisins. Quels sont les dangers du tabagisme passif de cannabis ? Comment un purificateur d’air pour le cannabis peut-il aider ? Continuez à lire pour en savoir plus.

Tabagisme passif de cannabis

Une partie importante des jeunes croient que la fumée secondaire de cannabis (également connue sous le nom de SHCS) est moins dangereuse que la fumée de tabac. En fait, 27 % des jeunes adultes interrogés pensent que les SHCS sont sûrs, selon UC Berkeley Public Health2.

Quels polluants/produits chimiques trouve-t-on dans la fumée de cannabis ?

Selon l’une des premières études de ce type, un article publié en 2022 analysait les effets de la consommation de cannabis en utilisant un bang à la maison. Les résultats ont révélé que le SHCS était plus toxique que celui de la fumée de tabac. Il contient plusieurs centaines de produits chimiques, dont beaucoup sont cancérigènes3. Cela présente un grave danger pour la santé de la fumée directe de marijuana et des fumeurs passifs. Plus précisément, les polluants atmosphériques suivants ont été analysés :

Particules fines

Levels of fine particle pollution, also known as particulate matter (PM), were extremely high. PM2.5 concentrations were 10 times greater in weed smoke than the levels measured during ‘orange sky days’ caused by wildfires and Sahara desert dust. Furthermore, particles released by marijuana smoke remain in the air for much longer than PM emitted by tobacco smoke: 12 hours after cannabis smoking had ceased, PM levels still exceeded the World Health Organization (WHO)’s recommendations3.

Typical PM levels in the home are as follows:

  • Non-smoking homes: 15 μg/m3
  • Cigarette-smoking homes: 44 μg/m3
  • Cannabis-smoking homes: 200 μg/m3
  • WHO recommendations: 10 μg/m3 for PM2.5, 20 μg/m3 for PM10

Volatile organic compounds (VOCs) Comp

A 2015 study compared urinary levels of VOCs and PAHs in cannabis smokers versus non-smokers. It found a significantly higher level of toxic byproducts of combustion (VOCs and PAHs specifically) in cannabis smokers compared to non-smokers4.

Some of the most common VOCs found in cigarette and cannabis smoke include formaldehyde, benzene, toluene, styrene, nitrogen oxides, xylenes, and ethylbenzene. Carbon monoxide is also found in cigarette smoke. In 2012, a list was published by the Food and Drug Administration (FDA) containing ‘harmful and potentially harmful constituents’ (HPHCs) found in cigarettes. The list includes 93 substances, 33 of which are VOCs5. The level of terpenes, natural compounds found in cannabis that give it its distinct marijuana odour when smoked, is one of the factors that determines the severity of exposure to HPHCs6.

Heavy metals and toxic gases

Marijuana smoke contains a variety of heavy metals. Cadmium, mercury, nickel, chromium, and lead are all found in cannabis smoke. Ammonia, hydrogen cyanide, nitrogen oxides, and other aromatic amines are all found in levels three to five times higher in marijuana smoke than cigarette smoke7.

Is cannabis smoke bad for your health?

Cannabis smoke is a throat and lung irritant. Certain aspects of smoking marijuana put the smoker and secondary-smoker at higher risk than a tobacco smoker. For example, marijuana joints are typically less tightly packed, meaning that more smoke particles and tar are inhaled. Marijuana smokers, on average, inhale more deeply and retain the smoke inside their longs for a longer period of time than a cigarette smoker. This longer exposure time amplifies the negative effects on health that the toxic substances found in cannabis smoke have on the body. This ultimately contributes to the increased risk of the following health effects.

‘Contact high’

Under extreme, short-term conditions with little ventilation, a second-hand cannabis smoker may experience the same effects as a first-hand smoker. This may include low to moderate sedative effects, minor cognitive impairment, and difficulties concentrating8. This is referred to as a ‘contact high’ and may cause a person who did not directly smoke marijuana to fail a drug test.

Cancer risk

A person who experiences exposure to marijuana smoke is at risk of the same adverse health effects as second-hand tobacco smoke. The biggest risk is multiple types of cancer, especially cancer du poumon. A 2008 study found that the risk of lung cancer increases by 8% every year that a person smokes a joint on a daily basis9. The California Environmental Protection Agency has identified ‘at least 33 constituents present in both marijuana smoke and tobacco smoke’ as carcinogenic10.

Une personne exposée à la fumée de marijuana risque de subir les mêmes effets néfastes sur la santé que la fumée de tabac secondaire. Le plus grand risque concerne plusieurs types de cancer, en particulier le cancer du poumon. Une étude de 2008 a révélé que le risque de cancer du poumon augmente de 8 % chaque année où une personne fume un joint quotidiennement9. L’Agence californienne de protection de l’environnement a identifié « au moins 33 composants présents à la1 fois dans la fumée de marijuana et dans la fumée de tabac » comme étant cancérigène10 .

Effects on immune, endocrine, cardiovascular, and respiratory systems

As with cigarette smokers, a heavy cough and chronic bronchitis are common amongst heavy marijuana users. Weed smoke is genotoxic and has negative effects on the immune, endocrine, and cardiovascular systems. A study on rats performed in 2016 found that second-hand cannabis smoke impacts blood vessels and endothelial function to an equivalent extent as tobacco smoke. However, it has an even longer-lasting effect11.

Since marijuana, specifically THC (tetrahydrocannabinol, the principal psychoactive component in cannabis), is immunosuppressive, smokers may be at higher risk of lung infections in those who are immunodeficient. It may also reduce the immune response in the respiratory system and increase the likelihood of acquiring a respiratory infection. Smoking marijuana is associated with inflammation of the large airway, increased airway resistance, and hyperinflation of the lungs12.

Minimise your exposure to the chemicals in marijuana smoke

A few tips to reduce your and your loved ones’ exposure to the harmful substances and chemicals in cannabis smoke are:

  • Smoke only in places that are well-ventilated: ideally outdoors, by a window, or near a fan
  • Reduce your paper usage to produce less smoke
  • Clean your home regularly to avoid the build-up of third-hand smoke and residue on your furniture and carpets
  • Convert to other cannabis consumption methods like edibles or vaporisation

The benefits of an air purifier for cannabis or weed

The main goal of investing in an air purifier for cannabis or weed smoke is to eliminate its smell/odours in your home and protect your health. An air purifier that is equipped with the proper air purification technology (or technologies) like activated carbon filters removes unpleasant marijuana odours that enter your home. If you are exposed to weed smoke that enters your room or your home from your neighbours who smoke it, protect your own health and well-being and that of your loved ones with an air purifier.

Reducing cannabis smoke in residential settings can not only improve indoor air quality, but it can also improve productivity. Studies have shown that in addition to all of its negative health effects, poor indoor air quality (IAQ) leads to reduced focus and concentration.

How to choose an air purifier for cannabis or weed smoke?

If you are a cannabis smoker yourself or are exposed to cannabis smoke by family members, roommates, or neighbours, an air purifier for cannabis or weed may be exactly what you need to protect your health. But how do you choose the right device? Consider the following when making your choice.

Choose the right filter

Not all filters will combat the fine particle pollution (particulate matter) emitted by weed smoke. Be sure that your filter contains a HEPA (high-efficiency particulate air) filter which guarantees the removal of 99.97% of particles down to a size of 0.01 microns. HEPA filters do not remove harmful volatile organic compounds (VOCs) or odours from marijuana smoke, however! Your device should also contain an activated carbon filter and photocatalysis technology in order to remove both VOCs and odours found in cannabis or weed smoke from your breathing air. Activated carbon filters are one of the oldest forms of air and water filtration, and they are extremely effective at removing unpleasant smells from marijuana and VOCs.

  • Even better: find a device that removes all types of air pollution. Eoleaf’s air purifiers use a proprietary 8-step technology (including both a HEPA filter and an activated carbon filter) that combats all kinds of air pollutants!
  • Keep in mind that ‘HEPA-type’ filters are not guaranteed to perform the same level or quality of filtration as HEPA-certified filters are.

Consider the size of your space

Air purifiers are made to filter the air in spaces of a maximum size. If you are looking to install a device in a room in your home, be sure that you choose a device that is properly sized for optimal filtration. The devices in Eoleaf’s product range are sized as follows:

Air purifiers are particularly useful for commercial cannabis cultivation facilities. The UK is the world’s largest exporter of legal marijuana, meaning that there are many employees working in this industry that may benefit from safer air in these facilities. Employees in the cannabis grower’s industry may be exposed to pesticides, insecticides, elevated levels of carbon dioxide (used to encourage plant growth), and even mould and spores from the high humidity environments required for large-scale plant growth.

Ensure proper placement

If you are a cannabis smoker yourself, consider the rooms in which you smoke most. Do you commonly smoke in your bedroom or living room? These are the rooms where installing an air purifier for cannabis smoke and odours would be ideal to fight against both cannabis odour/smell and its harmful effects. If you are a non-smoker but are exposed to marijuana smoke, place your air purifier as close to the points of entry as possible. Be sure that your device is unimpeded by furniture, walls, or other obstacles.
