This article was originally produced in partnership with Onsen Labs and featured Steven Gough, President of Onsen Labs & Gough Industries. It has been updated to distinguish the research findings from the manufacturer’s perspective.
Cannabis vaporization heats a cannabis product for inhalation. The research raises two separate questions: what a device delivers, and what that exposure means for health. Evidence about the first does not automatically answer the second.
Dry herb vaporizers and oil cartridges are different
A dry herb vaporizer heats plant material. Oil cartridges and concentrate devices use different preparations, so findings about a particular flower vaporizer should not be applied to every product described as a vape. The CDC notes that oils and concentrates can contain high levels of THC, additives or contaminants. Read the CDC’s explanation of cannabis use and risks.
What device research shows
In a 2016 laboratory study, researchers tested four electric vaporizers and one gas-powered device. The amount of THC and CBD recovered in the vapor varied between devices, and combustion occurred in the gas-powered device. This was a laboratory validation, not a clinical trial establishing long-term lung safety. Read the Lanz and colleagues study.
That distinction matters when evaluating product claims. Ask whether a cited experiment tested the exact model and material being sold, what it measured, and whether it involved people. A measurement of cannabinoid delivery cannot by itself support a claim that a device prevents disease or makes inhalation harmless.
Is vaporizing cannabis safer than smoking?
Avoiding smoke does not establish that a product is safe. The CDC says there is not enough evidence to rank one way of using cannabis as safer overall than another, and vaping has been linked to lung injury. THC can impair attention and decision-making regardless of the route. See the CDC’s comparison of consumption risks.
Claims that a vaporizer eliminates all harmful substances or guarantees a safe experience go beyond the evidence reviewed here. Device performance, product contents and health outcomes need to be evaluated separately.
Stronger THC delivery can mean stronger impairment
A 2018 crossover trial studied 17 healthy adults who had not used cannabis in the preceding month. At equivalent THC amounts, vaporized cannabis produced higher peak blood THC concentrations and generally stronger acute effects than smoked cannabis. The researchers measured effects including cognitive and psychomotor impairment. Read the Spindle and colleagues trial.
This small study examined short-term effects in infrequent users. It does not establish better treatment outcomes, long-term safety or results for every patient and device. More efficient delivery should not be presented as an automatic medical benefit.
Is there one ideal vaporizer temperature?
The device study above does not establish a universal setting for all products or a temperature that guarantees safety. Its results varied by device design. Treat claims about a single perfect temperature or predictable therapeutic effects from a boiling-point chart with caution: those claims require evidence beyond laboratory cannabinoid recovery.
The manufacturer’s perspective
In the original interview, Steven Gough said, “I actually think vaporization is one of the better methods to achieve a fuller profile.” This is an attributed industry viewpoint. The studies linked here do not establish that the Onsen product delivers superior clinical outcomes, and this article does not certify a particular device.
Questions to discuss with your clinician
- What evidence supports cannabis for the symptom I want to address?
- How do my health history and medicines affect the options?
- What benefits, adverse effects and follow-up would we monitor?
Cannabis can interact with medicines. Review your current medications with a qualified clinician before making treatment changes. The CDC explains why these interactions matter.
