Medical cannabis vaporisers and illegal electric vapes differ in more than just one way. This article will discuss the differences between vapes and vaporisers, and how the stigma for one seeps into the other.
It’s been some time since the widely reported cases of Vape Lung that swept the USA in 2019, but the problem remains.
Back in 2019, the United States experienced a sudden wave of severe lung injuries linked to illicit product vaping. The condition became known as EVALI — E-cigarette or Vaping-Associated Lung Injury.
More than 2,800 people were hospitalised, and dozens tragically lost their lives. Understandably, this event created widespread, global fear around vaping in all its forms.
There is, however, one crucial detail that often gets lost in headlines: EVALI was caused by illicit-market THC cartridges, contaminated with Vitamin E acetate, not by highly regulated medical vaporisers.
Patients need to understand the differences between unregulated and regulated products, so they can make informed decisions about their health and wellbeing.
The medical cannabis vaporisers prescribed by clinics bear no resemblance to the unregulated, dangerous products created by organised crime and sold in the illicit market.
Patients can be assured that medically prescribed vapes are manufactured to the highest pharmaceutical standards. They are manufactured under the Good Manufacturing Practice (GMP) standards and must be compliant with the Medicines and Healthcare products Regulatory Agency (MHRA).
Wellford Clinics is committed to harm reduction, transparency, and patient safety. This article explains the difference.
What actually caused EVALI?
Investigation conducted by the Centres for Disease Control (CDC) and Food and Drug Administration (FDA) concluded that:
· The vast majority of EVALI cases involved illicit THC cartridges purchased from unregulated sellers
· These cartridges were frequently adulterated with Vitamin E acetate, a thickening agent used to mimic high-quality cannabis oil. Products sold illicitly will often contain materials to thicken the product to maximise profits
· When inhaled, Vitamin E acetate can interfere with normal lung function, leading to severe inflammation and respiratory failure.
There have been no cases where EVALI has been reported in the MHRA Yellow Card scheme linking regulated medical cannabis vaporisers or products.
Why medical liquid vaporisers are different
Medical-grade liquid vaporisers, including those used in Wellford Clinics’ harm-reduction pathways, are designed with safety, purity, and consistency at their core.
Pharmaceutical-grade formulations
Medical cannabis liquids are produced under strict Good Manufacturing Practice (EU GMP) manufacturing standards. They contain:
- Purified cannabinoids
- Medical-grade carrier liquids (where applicable)
- No cutting agents such as Vitamin E acetate
- No pesticides, heavy metals, or residual solvents
- Every batch is tested
- Every ingredient is disclosed and traced through the supply chain.
Temperature-controlled devices
Medical vaporisers are engineered to heat dried flower to precise temperatures, avoiding combustion and minimising the formation of harmful by-products. In contrast, medical vapes are smaller devices used for concentrated cannabis oil.
Illicit vapes, by contrast, often use cheap hardware with inconsistent heating elements. This can burn contaminants or degrade the liquid into toxic compounds.
Traceability and accountability
Regulated medical products come with:
- Batch numbers
- Certificates of analysis
- Clear provenance
- Clinical oversight.
Illicit products offer none of these safeguards or information on where products are manufactured. This could be in someone’s kitchen, garage, or any unsanitary environment.
Vaporisation vs smoking: A harm-reduction perspective
Smoking versus vaping is a huge topic of discussion; however, it’s important to note that in the UK, it is illegal for patients to smoke their medication. There are also advantages for patients who vaporise their medication, these include:
- No combustion means no tar, carbon monoxide, or smoke-related toxins
- A faster onset can support better symptom control
- Lower temperatures can reduce irritation and preserve therapeutic compounds.
What Wellford Clinics patients can expect
Each patient is assessed and prescribed according to their specific needs and symptoms. Wellford Clinics offer medical-grade vaporisers and vapes aligned to regulation in their shop; these ensure:
Safety
Only regulated and approved products are recommended. Patients also receive guidance on device use, maintenance, and dosing.
Education
We help patients understand the difference between medical and illicit products. This empowers them to make informed decisions.
Harm reduction
Our approach prioritises reducing exposure to smoke, contaminants, and unregulated substances — especially for patients with respiratory vulnerabilities.
The Bottom Line
EVALI is a stark reminder of the dangers of the illicit market. The Medicines & Healthcare Regulatory Agency (MHRA) regulates and applies pharmaceutical standards to every import of CBPMs in the UK to ensure safety and consistency.
Medical cannabis products in the UK CBPM formulary are then continuously monitored for any possible reactions to ensure utmost safety.
At Wellford Clinics, patient safety is non-negotiable. Our commitment is to provide clear information, evidence-based guidance, and access to the safest therapeutic tools available.
