As public health becomes a top concern in the wake of global respiratory illnesses, cannabis consumers in the UK are asking an important question: is smoking or vaping cannabis the safer option?
While both methods deliver cannabinoids to the body, they differ significantly in terms of health risks. This guide examines the pros and cons of smoking and vaping cannabis—especially in the context of respiratory safety.
A Clear Warning for Those with Respiratory Conditions
Before diving into the details, it’s important to state the obvious: individuals with existing respiratory issues—or a family history of lung conditions—should avoid inhaling cannabis altogether. Whether through smoke or vapour, the lungs are still the delivery system, and there are alternative consumption methods such as edibles, tinctures, or capsules that offer safer routes.
Is Smoking Cannabis Safe?
Smoking remains one of the most common ways to consume cannabis in the UK. When smoked, cannabis compounds are absorbed through the lungs and quickly enter the bloodstream, delivering fast-acting effects.
What Smoking Cannabis Delivers:
-
THC: The compound responsible for euphoria, altered perception, and, in higher doses, potential paranoia.
-
CBD: Offers therapeutic effects such as anti-anxiety, pain relief, and anti-inflammatory properties.
-
Terpenes and Flavonoids: Provide cannabis strains with unique aromas and flavour profiles, which may offer additional wellness benefits.
The Risks of Smoking:
-
Combustion Byproducts: Smoking cannabis involves burning the plant material and rolling paper, which produces harmful toxins and carcinogens.
-
Respiratory Irritation: Smoke passes through the mouth, throat, and lungs—potentially causing red eyes, dry coughs, and inflamed airways.
-
Cumulative Damage: Frequent use, particularly among those who also smoke tobacco or drink alcohol, may increase the risk of long-term respiratory conditions.
When is Smoking Less Risky?
For infrequent users—say, those who enjoy a joint at the weekend or during social gatherings—the risks are considerably lower. However, even casual smoking may not be advisable during flu season or respiratory pandemics.
What About Vaping Cannabis?
Vaping cannabis involves heating, not burning, either dry herb or cannabis oil to release active compounds in a vapour. This vapour is then inhaled, delivering THC, CBD, and other cannabinoids without combustion-related toxins.
Benefits of Vaping Over Smoking:
-
Lower Heat = Fewer Toxins: Vaping doesn’t burn the material, avoiding many of the carcinogens created through combustion.
-
Less Irritation: Vapour is typically cooler and less harsh on the throat and lungs.
-
More Discreet: Vaping produces less odour and is often easier to use in private or public settings.
Risks to Watch For:
-
E-Liquid Safety: In 2019, concerns grew around vaping-related lung injuries, especially in the US. Many cases were linked to poor-quality vape cartridges containing Vitamin E acetate and other harmful additives.
-
Unregulated Products: In the UK, where cannabis is not fully legalised, buying unverified products from unregulated sources (especially online) carries serious health risks.
How to Vape Safely in the UK:
-
Buy from trusted CBD retailers or UK-based medical cannabis clinics.
-
Ensure your vape liquids or concentrates are third-party lab tested.
-
Choose reputable vaping devices and avoid DIY modifications.
