Do THC Disposable Vapes Have Metal In Them?

As the popularity of vaping THC (tetrahydrocannabinol) has increased, THC disposable vapes have become increasingly popular, especially in states where marijuana is legal. However, because these disposable vape pen use heating elements to heat THC oil, consumers have been seared worried Vape pens contain metals and whether metals will cause harm to the body.

To answer this question, let’s understand the components of a disposable THC vape cartridge first. These cartridges typically consist of a glass or plastic container that holds the THC oil, a heating element, and a mouthpiece.

The heating element is usually made of a metal wire, typically titanium or nichrome, which heats up the oil and creates vapor. When the coil is heated, some of the metal is released into the surrounding oil, which then enters the aerosol and can be inhaled by the user.

A study was conducted in 2021 by researchers at Johns Hopkins University. The study analyzed the aerosol produced by several different brands of THC disposable vapes, looking for the presence of metals such as lead, chromium, and nickel. The study found that all of the vapes tested contained at least one type of metal, with some containing up to four different metals. The most common metal found was lead, which is a known neurotoxin that can cause serious health problems.

While the study did find the presence of metals in THC disposable vapes, it is important to note that the levels detected were generally low. The researchers concluded that the health risks associated with vaping metals in these amounts are not fully understood and warrant further investigation.

Will the metal in the disposable vape pen cause harm to the user?

We know that the components of disposable vape pens are indeed made of metal. It doesn’t make sense for us to talk about a chemical without a risk and dose assessment.

Because metals are ubiquitous in the environment, including air, water, food, dietary supplements, drugs, and more.

But for now, with the improvement of product technology and manufacturing, the trace metals released by the heating components in electronic cigarettes will not pose a threat to health.

However, some low-quality vape cartridges may contain heavy metals like lead, chromium, and cadmium, which can leach into the oil and be inhaled when the oil is vaporized.

If the heavy metal dosage in disposable vape pens exceeds the standard, it will damage the health of users.


What damage will heavy metals cause to users?

The potential for heavy metal contamination in vape cartridges is a serious concern, as inhaling these substances can have harmful effects on health.

Heavy metal exposure can cause a range of health problems, including lung damage, kidney damage, and developmental delays in children.

Why Should We Do Heavy Metal Testing in Disposable Vapes?

Heavy metal testing is crucial in disposable vapes to ensure that the user is not exposed to harmful metals such as lead, cadmium, and chromium, which can have serious health effects when inhaled.

It also helps to identify low-quality products and ensures that manufacturers comply with safety standards.

As a vaporizer manufacturer, RELEAFY carries out heavy metal testing on each product.

How to avoid purchasing heavy metal devices?

  • Choose your vape pen manufacturer carefully

To avoid exposure to heavy metals in disposable THC vape cartridges, it is important to choose high-quality products from reputable manufacturers. Look for products that have been independently tested for heavy metals and other contaminants. Many states require testing of THC vape cartridges for heavy metals, so it is worth checking the packaging or the manufacturer’s website to see if the product has been tested.

  • Choose the ceramic heating elements disposable vape pen

You may want to look for vapes that use ceramic heating elements instead of metal. Ceramics is an inert material that is less likely to release particles during use. You can also look for products that have been independently tested for metal content and other potential contaminants.

  • Pay attention to the usage of the cartridge

In addition to choosing high-quality products, it is also important to use disposable THC vape cartridges responsibly. Follow the manufacturer’s instructions for use, and avoid overheating the cartridge or using it past its recommended lifespan. Overheating can cause the heating element to break down and release harmful chemicals into the vapor.

It is worth noting that the use of disposable THC vape cartridges has come under scrutiny in recent years due to reports of lung injuries associated with vaping. In 2019, there was a nationwide outbreak of lung injuries linked to vaping, which affected over 2,800 people and resulted in 68 deaths.

While the exact cause of the outbreak is still being investigated, it is believed that the use of vitamin E acetate as a cutting agent in THC vape cartridges played a significant role. Vitamin E acetate is an oil-based substance that was used to thicken THC oil and improve its viscosity. However, when vaporized and inhaled, it can cause serious lung damage.

To avoid exposure to harmful cutting agents like vitamin E acetate, it is important to choose products that have been independently tested for purity and to avoid products that contain additives or cutting agents. Look for products that use only high-quality THC oil and natural terpenes for flavor and aroma.


In conclusion, disposable THC vape cartridges do contain metal in the heating element, but the oil itself is typically free of metals. However, there is a risk of heavy metal contamination in low-quality products, so it is important to choose high-quality products from reputable manufacturers and use them responsibly.

By taking these factors into account, you can make informed decisions about your THC vaping experience.

If you know that RELEAFY has always been committed to producing healthy and non-toxic vaporizers, would you feel at ease to use them for customers?

We voluntarily test all our vaporizers for heavy metals and pass the lead-free test.

RELEAFY’s vaporizers use medical-grade stainless steel center columns, glass or PC mouthpieces, food-grade PCTG oil tanks or glass oil tanks, and ceramic or quartz glass heating chambers. No center tube disposable vape pens have even been designed to eliminate or reduce heavy metals and their use across our entire line of carburetors.
