VAN NUYS, Calif. – California cannabis testing lab CannaSafe has released benefits of tests carried out on illicit and counterfeit THC-infused vape cartridges, as nicely as samples from legal organizations.
“California has the strictest cannabis item testing regulations in
the nation, and the licensed solutions proved to be free of charge of contaminants and
harmful pesticides,” the CannaSafe report study.
On the other hand, in its initial findings, CannaSafe pointed out “alarmingly higher levels of pesticides and cuttings agents, specifically Vitamin E acetate, located in cartridges bought on the illicit marketplace.”
The report titled, “Vapes: What are You Basically Inhaling?” specifics test benefits CannaSafe released on October five, following the mysterious vaping-associated condition—now named EVALI—first began getting reported by overall health officials in late August.
In total, the lab tested seven THC vape cartridges from legal shops, manufactured by legal producers, as nicely as seven illicit and counterfeit cartridges, bought from illicit vendors or delivery solutions in the Los Angeles location.
Although the legally bought cartridges have been identified only
by letter (Cartridge A, B, and so forth.), illicit cartridges have been “brands” like
Cereal Carts, Exotic Cart, and Dank Vapes. Two much more cartridges have been counterfeit
versions of legal producers Kingpen and Stiiizy brands.
The lab tested 4 places of concern for overall health officials
and vape customers, which incorporated cutting agents, temperature, flavorings, and
Early in the vaping crisis, several sources speculated Vitamin E acetate, a widespread thickening agent in topical and ingestible formulas, may well play a function in lung injury suffered from vaping.
Final week, the Centers for Illness Handle (CDC) announced that Vitamin E acetate was located in all lung fluid samples of twenty-nine sufferers with EVALI, as portion of an ongoing, multi-agency investigation into the vaping illness. Some specialists speculated that dangerous toxins may well be created when Vitamin E acetate (or other vape liquid components) are super-heated throughout the vaping procedure.
Vitamin E acetate is utilized as a “cutting agent” in vape cartridges to realize right volume of oil contained in each and every cart. The additive was located in all of the illicit cartridges tested the counterfeit Kingpen had the least quantity at just more than thirty %, even though the Cereal Carts “Trix” flavored cartridge contained pretty much thirty seven % of Vitamin E acetate.
CannaSafe went on to say that even though regulation of cutting agents would be valuable in stopping harm to vape customers, customer protection would also advantage from enforcement of clear labeling needs.
Vaping temperature is considerable, the lab mentioned, due to the fact higher temperatures may possibly alter even normally utilized compounds (like Vitamin E acetate) and super-heating these compounds may possibly create toxic chemical reactions.
“A study of 4 various cutting agents (propylene glycol [PG], vegetable glycerin [VG], polyethylene glycol 400 [PEG 400], and medium chain triglycerides [MCT]) located that all 4 created measurable amounts of acetaldehyde, acrolein, and formaldehyde when heated to 230°C (446°F),” the report study.
In regards to vape business suggestions for temperature, CannaSafe mentioned that recommended heat settings are not apparent to shoppers.
“Only a single legal cartridge offered advisable settings of any sort, listing a ‘recommended voltage’ of three.5V on the packaging. Primarily based on our critique of different sources, this appears to match basic business-wide suggestions of ~3V.”
The report also mentioned shoppers may possibly be additional confused about temperature due to the fact there is no a single common unit of temperature measurement at present getting utilized by vape item producers. As an alternative of degrees in Celsius of Fahrenheit, heating increments may well be described by voltage, watts, or OHMs, which supplies tiny guidance for shoppers in figuring out a protected or optimal heat setting.
“There demands to
be much more transparency into the hardware’s vaporizing temperature. For this
study, we compared voltage settings of three.5V vs. five.8V. We located that even the
oil in legal cartridges broke down into unfavorable chemical substances when vaporized at
greater voltage settings,” mentioned CannaSafe.
Right after testing illicit vape cartridge contents at a higher temperatures, benefits showed, “formaldehyde, carbon monoxide, and hydrogen cyanide have been located in the illicit Kingpen (>50ppm), Exotic Cart Maui Wowie (>50ppm), and illicit Stiiizy (5ppm) cartridges.”
Flavorings in THC-infused solutions are normally derived from terpenes that are extracted from cannabis or other plants. Synthetic terpenes can also be designed in the lab, and are normally added to processed foods and other flavored solutions.
Once again, the report showed that even though terpenes are a widespread additive, the procedure of super-heating that happens throughout vaping may well alter terpene compounds, resulting in a toxic by-item or chemical reaction.
Tests also showed terrific disparity in the quantity of terpenes contained in each and every of the cartridges, specially when compared with the level of cannabinoids (cannabis plant compounds, like psychoactive THC) in each and every cartridge.
on the legal marketplace all contained at least eighty 5 % cannabinoids,
and much less than ten % terpenes.
Of the illicit cartridges levels of cannabinoids varied drastically, from a low of just more than thirty %, to a higher of tiny much more than seventy two %, in the counterfeit Stiiizy cartridge. Levels of terpenes also varied, from much less than a single % in the Stiiizy cartridge, to practically eight % in the Cereal Carts Trix blend.

Lastly, hardware and heavy metals have been examined by CannaSafe’s researchers, who brought to light a further unregulated location of concern—the actual vaping hardware. Vape rigs, e-cigarettes, and the supplies utilized to make them, apparently, also are largely unregulated.
This led CannaSafe’s testers to recommend that much more analysis is required to see if speak to with different hardware elements may well impact e-liquids, either from cartridge supplies or when utilized with a device.
“Our study located that the illicit CBD cart purchased on the net contained more than 17x the acceptable quantity of lead (limit is .five ug/g), the cart measured eight.640 ug/g of lead, which may possibly be due to leaching introduced from the hardware,” the report study.
“Since batteries with their personal potentially hazardous supplies are incorporated into just about every vape pen and equivalent device, the connections amongst batteries and cartridges need to also be deemed on a case-by-case basis to determine attainable sources of contamination in the final item, each as oil and vapor,” it added.
In summing up the findings, CannaSafe emphasized that the illicit vape solutions it tested contained a potentially dangerous array of pesticides, adulterants, toxic chemical substances, and heavy metals that may possibly be catalyzed by vaping at higher temperatures.
Noting that all the legal cartridges that have been tested have been compliant with California state business regulations and created safer vaping solutions. Non-regulation in states exactly where cannabis is nevertheless illegal, the report recommended, has led to an illicit marketplace for solutions, given that shoppers have no legal access.
“It is very most likely that the illicit solutions in states with no health-related or recreational applications are filled with much more adulterants due to a lack of regulations or education for shoppers and producers,” CannaSafe mentioned in conclusion, adding, “We encourage all shoppers to invest in legal solutions from licensed dispensaries.”
CannaSafe’s report was also featured on media platform NBC News this week.
