As the heavy metals testing standards went into effect this January, it was found that many vape cartridges on the market were manufactured with parts containing heavy metals. The emergence of serious lung injuries associated with vaping reinforces the scrutiny on vape cartridges across the industry. In continued pursuit of transparency for our customers, the revolutionary design of the CleanCart features a PCTG core, providing glass-like clarity with high-impact and chemical resistance, eliminating the traditional metal core found in most cartridges.
Trust is important, but so is verification; That’s why we’re committed to keeping you informed on our lab testing procedures and results.
We have held a None Detect status in our Heavy Metals testing from the Cartridge itself to the oil that has been stored inside.
NONE DETECT, NOT JUST PASSED.
The vapor from carts from regulated companies showed no harmful chemicals when vaped to a temperature consistent with a vape battery of 3 volts. But when heated with a more powerful voltage, even the vapor of licensed carts showed the presence of harmful chemicals known as HPHCs, which are also found in tobacco smoke.
“At the high temperature, we found considerably high amounts of formaldehyde, carbon monoxide, and hydrogen cyanide in some of the illicit carts,” Frazier told High Times. “None of the legal products produced these three chemicals, but low levels of other harmful and potentially harmful constituents like benzene and toluene were found in the legal carts at higher voltages.”
To address the issue, Frazier recommends that cannabis manufacturers adopt more sophisticated vaping hardware as the industry standard.
“We know that a lot of our licensed partners have mechanisms to control temperature on their devices, and this same level of quality needs to be implemented across the industry,” he said. “Our current regulations give us the cleanest oil in the nation, and now we must update them to include hardware.”
Noting that most of the reported cases of EVALI appear to have been caused by THC vape cartridges purchased from unlicensed sources, Frazier says that the best way for consumers in legal states like California to protect themselves is to ensure that they are buying from a licensed retailer.
“CannaSafe continues to urge consumers to stay away from illicit cannabis products and to buy legal products from licensed dispensaries.
New tests reveal the toxins present in vapor after cannabis oil is heated and vaporized prior to inhalation.
New data from a California laboratory show that THC vape cartridges may carry a substantial risk of exposing users to harmful chemicals. And while the test results from analytic laboratory CannaSafe show that illicit market products pose the most danger, even carts from licensed companies may be unsafe if used improperly.
1- The plastic casing was first separated from the outer metal casing on the cartridge using glass cutters.
2- The plastic casing was weighed and then allowed to soak in concentrated nitric acid (10 mL) for roughly 12 hours to ensure sufficient extraction of any arsenic, cadmium, mercury, or lead from the surface of the plastic.
3-The resulting nitric acid extract was transferred to a 25 mL volumetric flask and diluted to the mark.
Injected into the ICP-MS instrument for the test.

We all know the issues with the Heavy Metals that is in all cartridges in the market today and what the negative side effects are.
“We’ve found on the order of 25 or 26 different elements, including metals.”
Says Prue Talbot, a professor of cell biology at the University of California, Riverside, and co-author of several of the studies.
“Some of the metal particles are less than 100 manometers in diameter, and those are a concern because they can penetrate deep into the lungs.”
Medical cannabis regulators expanded testing for heavy metals in marijuana products as they warned the public about the risk for possible lead contamination in popular vaping cartridges.
“To notify patients and other stakeholders of potential lead contamination of cannabis liquids in vape cartridges following exposure to heat.”
THE BALTIMORE SUN
“You haven’t seen any heavy metals at the grow level” above safety limits, said Manoj Adusu of Quales LLC, one of the certified testers.
“We haven’t seen any heavy metals at the processing side.
The only other source would be the vape pen.”
In cheaply made metal cartridges as opposed the heat that creates the vapor could cause lead to leach
into the product, Adusu and other experts said.
When companies want to cut costs they may use “low quality vape cartridges” that can more easily release lead, he added.
We will outline a rational harm-reduction based approach for
evaluating the safety of these products.
The early symptoms of VAPI are often mild and resemble pneumonia ("horse"). Many of the VAPI ("zebra") patients presented in an outpatient setting, were initially diagnosed with respiratory infections, and treated with antibiotics (without improvement). Workups were negative for infectious agents, and chemical exposure of unknown type/origin is now believed to be the cause of VAPI. The majority of patients who develop this illness exhibit clinical improvement only after treatment with systemic corticosteroids.
The CDC encourages clinicians to report possible cases of e-cigarette or vaping-associated lung injury to their local or state health department for further investigation:
High Index of Suspicion
Silver solder (often contains cadmium) is used to make stable unions between dissimilar metals such as copper and stainless steel. In lower-end vape pens, large beads of this type of solder are present on positive and negative heating element connections. Most vape pens use cadmiun-free solder. Unscrupulous manufacturers have a financial incentive to cut corners. It's happened before: https://en.wikipedia.org/wiki/2008_Chinese_milk_scandal
Money and ease of use. Cadmium-containing silver solder is less expensive than cadmium-free alternatives, and has improved flow properties which facilitate the joining of dissimilar metals found in vape pen electrical components.
Upwards of 20-30 mg of solder alloy is permeated with vape juice liquid and directly in the airflow path through the vape pen.
Blood cadmium levels are indicative of recent exposure, whereas urinary cadmium is indicative of chronic, longer term exposure. Normal blood cadmium is <5.0 ng/mL, with most results in the range of 0.5 to 2.0 ng/mL, whereas tobacco smokers typically have blood and urinary cadmium levels more than double those of nonsmokers.
Other concerns involve materials used in the aerosol generation process, aging and fouling. e-cigarettes that use a heating mechanism to create a vapor emit metallic particles and even nano particles of heating coil components in the aerosol, such as tin, iron, nickel and chromium,
Lead, nickel and chromium appear on the US Food and Drug Administration's (FDA) ‘harmful and potentially harmful constituents (HPHC) list’.
The safety of the inhalation of these metallic particles and nano particles has not been studied and could be a cause for concern.
The use of alternative aerosol generation mechanisms may mitigate some of these safety questions.
There have been people getting sick from THC carts, box mods, and even juul pods, right??? Not just one kind of vape…
The only thing that is consistent among them is the hardware.
Update: Signs and symptoms of vaping-associated pulmonary injury (VAPI) are consistent with chemical inhalation. Analysis of symptoms, commonality of exposure source (vape pen battery cartridges), and mechanism ("vaping") may indicate cadmium-derived metal oxide fume inhalation (metal fume fever, cadmium pneumonitis) as a possible cause of the syndrome ("VAPI").
One UK study provides some support to Conrad, as it found that most commercially available vape devices produce heavy metal fumes.
Completely removing the risk of lead contamination from the metal components will require a change in production process in the metal foundries in China and then it will come into the hands of the manufacturers.

What we have done with the
Metal Free Cartridge
This is where we made the changes
over 2 years ago.
we started our Metal free crusade.
Even clean extract is not safe from contamination. A significant portion of the electronics used in vape carts are produced at metal foundries in China, where it is common to add small amounts of lead into the brass and copper feedstocks to make the metals more moldable when shaping into electronics. Even though the Chinese metal foundries purport to follow strict regulations which cap lead at 4% or 40,000 parts per million, these laws were designed for electronics and not consumption devices, like vape cartridges. As a result, the Chinese standard is much higher and does not match with the new controls in California, where detectable lead levels must be under 0.5 parts per million.
[It must be noted that just because the metal used in vape carts contains up to 40,000 parts per million of lead, that doesn’t necessarily mean that the cannabis oil inside the cart will be contaminated. Various factors such as the length of time of the oil in the cart, the environment in which the cart is stored, and the temperature at which the oil is heated, may all factor into how much lead migrates into the oil.]
The Chinese foundries are aware of the lead contamination issue and are implementing procedures to reduce the amount of lead used during manufacturing. Cartridges in the future may be free of lead but it is unclear how long it will take until the changes are implemented or when stocks of contaminated cartridges already in the US will be exhausted.
Last, it is possible that analytical laboratories may be the cause of some of the variability in heavy metal findings. Standard methodologies for cannabis heavy metal testing do not yet exist and most cannabis-only labs have little experience performing the analysis. If a laboratory’s internal methods and protocols are not properly validated, additional leaching or contamination could occur during sample preparation or testing, resulting in the reporting of false positives.
California’s cannabis testing requirements tightened further on January 1, 2019 with the introduction of the BCC’s Phase III compliance regulations — mandating, amongst other things, heavy metal testing of all cannabis products. While all product categories have been impacted by the change, vaporizer cartridges (disposable delivery devices similar to e-cigarettes) in particular have struggled to meet the new permitted limits for lead.
SHENZHEN, China — In a grimy workshop, among boiling vats of chemicals, factory workers are busy turning stainless steel rods into slender tube casings, a crucial component of electronic Vape device.
