E-liquids, commonly known as vape juice or e-juice, are the primary components of electronic cigarettes and vaping devices. They come in a variety of flavors and nicotine strengths to suit individual preferences. While the majority of e-liquids do not contain alcohol as a standard ingredient, there are exceptions. Certain manufacturers may add a small quantity of alcohol to enhance the flavor or aid in the blending process. Research conducted by Virginia Commonwealth University professor Michelle Peace, Ph.D., revealed that out of 56 commercially available vape juice samples, all but three contained ethanol, with 11 containing more than 10% ethanol. The presence of ethanol in e-liquids raises concerns about potential health and safety implications, especially for individuals with respiratory sensitivities or those in programs that require abstinence from alcohol.

What You'll Learn
E-liquids often contain ethanol as an unlisted ingredient
E-liquids, the flavoured nicotine solution used in e-cigarettes, often contain ethanol as an unlisted ingredient. Out of 56 commercially available vape juice samples tested by associate professor Michelle Peace, Ph.D., and her lab at Virginia Commonwealth University, all but three contained ethanol, and 11 contained more than 10%.
Ethanol is commonly used as a solvent for flavouring chemicals. As Peace explains, "if you’re going to be using natural vanilla extract, you’re going to wind up with small amounts of ethanol in the e-liquid." However, the high concentrations of ethanol found in some e-liquids were surprising, and the implications of vaping ethanol are not yet fully understood. Peace is currently investigating these implications with the help of two grants from the National Institute of Justice totalling approximately $1.8 million.
One concern is that vaping ethanol could lead to false positive results on breathalyser tests, which could be used as a defence tactic in court cases involving driving under the influence. In addition, people who are vaping ethanol and are on probation or in a clinic for substance abuse treatment could unknowingly be violating the requirements of their program.
Another concern is the potential for impairment while vaping ethanol. As ethanol is inhaled rather than ingested, it bypasses the gut, which normally provides a layer of protection when alcohol is swallowed. There is some suggestion in online vaping forums that people may be experiencing momentary impairment while vaping ethanol. However, Peace does not expect her lab to find that vaping ethanol can lead to high levels of impairment.
In addition to ethanol, Peace's research has also discovered other unlisted ingredients in commercially available CBD e-liquids, including a synthetic cannabinoid linked to deadly overdoses and a chemical found in cough syrup.

Potential health and safety concerns of vaping ethanol
E-liquids often contain ethanol, or alcohol, as an unlisted ingredient. Out of 56 commercially available vape juice samples, all but three contained ethanol, and 11 contained more than 10% ethanol. The implications of vaping ethanol are not yet fully understood, but there are several potential health and safety concerns to be aware of.
Firstly, vaping ethanol can lead to false-positive results on police field sobriety or breath alcohol tests. This could have serious legal consequences for individuals on probation or in court, as they may unknowingly violate the requirements of their program or be wrongfully convicted of driving under the influence.
Secondly, vaping ethanol may cause momentary impairment or intoxicating effects. By inhaling ethanol, users bypass the gut, which normally provides a layer of protection when alcohol is swallowed. High concentrations of inhaled ethanol could potentially lead to unexpected impairment or drunkenness.
Thirdly, the presence of ethanol in e-liquids may indicate the presence of other unlisted and potentially harmful ingredients. For example, some CBD e-liquids have been found to contain unlisted synthetic cannabinoids linked to deadly overdoses and chemicals found in cough syrup.
Finally, vaping, in general, has been associated with respiratory problems, lung disease, asthma, and cardiovascular disease. While e-cigarettes generally contain fewer harmful chemicals than traditional cigarettes, they still expose users to potentially dangerous substances, including nicotine, which is highly addictive and particularly harmful to pregnant women and developing fetuses.
Overall, while the specific effects of vaping ethanol require further research, it is clear that vaping carries potential health and safety risks that users should be aware of.

Vaping ethanol and field sobriety tests
E-liquids, the flavoured nicotine solution used in e-cigarettes, often contain ethanol (alcohol) as an unlisted ingredient. Out of 56 commercially available vape juice samples, all but three contained ethanol, and 11 contained more than 10% ethanol. This raises concerns about the impact of vaping ethanol on field sobriety tests.
To address this concern, a human clinical study was conducted in collaboration with the Virginia Department of Forensic Science and the VCU Police Department. The study aimed to evaluate the impact of vaping ethanol on field sobriety and breath alcohol tests. Thirteen participants vaped e-liquids with either a concentration of 20% ethanol or 0% ethanol. Before and after vaping, Lt. Edgar Greer of the VCU Police administered preliminary and evidentiary breath tests, as well as a standardised field sobriety test.
The results of the study showed that vaping ethanol did not impact the standardised field sobriety test or the evidentiary breath test. The standard wait period of 15-20 minutes employed by law enforcement before administering a breath test was effective in negating vaping-related false positive breath ethanol results.
However, it is important to note that the impact of vaping ethanol in combination with drinking alcohol is still being studied. The researchers plan to collect blood, urine, and saliva samples from participants who vape e-cigarettes containing ethanol and consume alcoholic beverages. They aim to analyse ethanol metabolites in these fluids to better understand the effects of combining vaping and alcohol consumption.
While the initial findings suggest that vaping ethanol does not impact field sobriety tests, further research is necessary to comprehensively understand the implications of vaping ethanol, especially when combined with alcohol consumption.

Alcohol-free alcohol-flavoured e-liquids
Research conducted in the lab of Virginia Commonwealth University professor Michelle Peace, Ph.D., found that commercially available vape juice samples frequently contain ethanol (alcohol) as an unlisted ingredient. Ethanol is often used as a solvent for flavouring chemicals. However, it is important to note that the presence of ethanol in e-liquids may have potential health and safety implications that are not yet fully understood.
That being said, there are e-liquids on the market that are specifically advertised as being alcohol-free and tobacco-free, while still offering alcohol-flavoured options. These e-liquids typically contain flavourings that mimic the taste of alcoholic beverages without containing any actual alcohol. For example, ECBlend Flavors offers a range of liqueur and cocktail-flavoured e-liquids, including margarita, mojito, champagne, and bourbon options, all of which are explicitly stated to be alcohol-free. Similarly, Joose Juice offers alcohol-flavoured e-liquids like dark rum, Irish cream, and piña colada, but it is unclear whether these contain alcohol or not. On the other hand, VaporFi advertises alcohol-flavoured e-liquids, such as bourbon, without specifying whether they contain alcohol.
The availability of alcohol-free, alcohol-flavoured e-liquids is important for several reasons. Firstly, it allows individuals to enjoy the taste of their favourite alcoholic beverages without experiencing intoxication or impairment. This can be particularly beneficial for those who are unable to consume alcohol due to health, religious, or personal reasons. Additionally, the presence of alcohol in e-liquids can have unintended consequences for individuals who are on probation, in substance abuse clinics, or subject to drug courts. If these individuals unknowingly vape high concentrations of ethanol, they may test positive for alcohol consumption, leading to violations of their program requirements.
While the specific effects of inhaling ethanol are still being studied, the potential for momentary impairment and the bypassing of the gut's protective layer when ingesting alcohol are concerns that have been raised. As such, it is important for consumers to be aware of the presence of ethanol in their e-liquids and to make informed choices based on their own health and legal considerations. It is also worth noting that the regulatory requirements for e-liquid products may vary by region, and it is the responsibility of the consumer to ensure that they are complying with any age restrictions or other relevant laws pertaining to the purchase and use of these products.

E-liquid manufacturers may use alcohol to enhance flavour
E-liquids, also known as vape juice or e-juice, are the flavoured nicotine solutions used in electronic cigarettes and vaping devices. While the primary ingredients in e-liquids are typically propylene glycol (PG) and vegetable glycerin (VG), some manufacturers may also add small amounts of alcohol.
The inclusion of alcohol in e-liquids is typically minimal, and its purpose is to enhance the flavour or help blend the ingredients more effectively. However, research conducted by Virginia Commonwealth University professor Michelle Peace, Ph.D., revealed that out of 56 commercially available vape juice samples, all but three contained ethanol, and 11 contained more than 10% ethanol. This finding raises concerns about the potential health and safety implications of vaping ethanol, especially for individuals who are on probation, in drug courts, or in a clinic for substance use and abuse.
One concern is that vaping ethanol can lead to false-positive results on drug tests, as the ethanol metabolites can be detected in urine. Additionally, bypassing the gut by inhaling ethanol may result in momentary impairment, affecting coordination and equilibrium. While the health risks of inhaling small amounts of alcohol vapour are generally considered low, it can be problematic for individuals with respiratory sensitivities or those prone to irritation.
To make an informed decision about vaping, it is essential to check the labels on vape products to understand the ingredients and potential variations among different brands and batches. Responsible vaping also entails acknowledging potential risks and refraining from combining vaping with alcohol consumption or other consciousness-altering substances.
