The Bottom Line on Vaping Today

/in /by

Recent reports indicate that in addition to fruit juices and flavors such as menthol and bubble gum, two natural products may be contributing to the issues with vaping: vitamin E and CBD oil. Vitamin E has been found in some vaping cartridges that contain CBD oil. CBD, short for cannabidiol, is the second most abundant cannabinoid found in the cannabis plant. It has levels of THC (tetrahydrocannabinol) below the legal limit and is often used for pain relief and psychological distress such as anxiety. I can’t comment on CBD oil; it’s not my area of expertise.

What I do know is that while cannabis is typically inhaled, CBD oil can be administered orally or topically and that’s probably a better delivery system. When any oil is produced, vitamin E is typically added so the oil doesn’t go rancid. In addition, there may be other additives so the CBD doesn’t break down. There’s no research to suggest that the oil or the vitamin E are safe when incinerated. Even if a cold aerosolized process is used, the ingredients are not designed to be administered that way.

Lung tissue is very sensitive. Think of the aerosolized droplets thousands of times larger than individual molecules of vitamin E or omega-3 fatty acids that would be found in blood. Those droplets would create a barrier, making it tough to breathe, whether natural or not. The benefit relies on the absorption and while some would be absorbed quickly, how long would the residue remain? Could it even be removed?

The Bottom Line Today

As I said in the Tuesday Memo, the governor of Michigan banned the sale of flavored vaping products; I think she made the right decision even though she is taking political heat for it. Business interests have interfered in public health initiatives for too long. Do I even have to mention the tobacco industry? And that it has heavily invested in the vaping industry? With the health of a generation at stake, I think taking time to examine the safety and marketing of these products is warranted.

I wish I could say this is the last word on vaping, but this is a rapidly changing health topic. The only vaping that should be allowed is as a method for quitting smoking—not to replace smoking, but as part of a strategy to quit smoking. It should be regulated by the Food and Drug Administration because nicotine is a drug.

As for the rest of what’s being used in vaping products, I think everyone should take a pass. If the industry actually conducts safety testing to discover any health issues for vapers, maybe, but I just don’t see that happening. The burden shouldn’t be on the health industry to prove vaping is bad; the burden should be on the vaping industry to prove it’s safe. We do enough to ourselves already to impair our health. We don’t need to add any more habits that we’ll need to break in the future. If you smoke, there’s no question you should quit. Talk with your doctor about the best way to accomplish that before you start vaping.

Is Vaping Healthy?

/in /by

Two years ago, I wrote this about vaping’s potential negative effects: “We won’t know how harmful it is for years, possibly decades, when those who began vaping years ago are tested and found to have higher rates of lung disorders.”

I was wrong; we’re seeing serious lung issues now and even a few deaths. Reports of respiratory illnesses include pneumonia and asthma-like symptoms that impede breathing. Another issue appears to be seizures in some cases. The problem is that no one can identify what’s causing the problem.

One cause might be heavy metals that are aerosolized from the vaping devices as well as metal juice cartridges such as chromium, nickel, and lead. They may be irritants to lung tissue. Lead could also explain seizures in some vapers.

I think that the juices targeting young vapers could be a major source of contaminants. Juices may be natural or synthetically produced, and we might point the finger at synthetic flavors. However, there’s no research on what incinerating natural juices would produce. Phytonutrients are meant to be eaten; what could happen to them when they’re burned? They may end up being toxic due to the change in chemical structure caused by exceeding normal cooking temperatures.

There are still other possibilities so I’ll finish this up on Saturday.

Flavored E-cigs Banned in Michigan

/in /by

If you’ve been paying attention to the health news at all, you know that there have been some serious respiratory issues and deaths related to vaping. Because the majority of patients were young and were using flavored juices in the vaping products, Michigan Governor Gretchen Whitmer placed a temporary ban on the sale of all flavored e-cigarette products in the state. I applaud the governor’s action. It gives the legislature six months to come up with reasonable legislation governing vaping and vaping products.

This is not a simple issue. Health is the primary concern, especially the health of teenagers and young adults. But because of the prior lack of regulation, the vaping industry has grown to be a multi-billion dollar industry. They’re firmly entrenched, much as the tobacco industry was. They’re not going to go quietly.

The products are being pitched as healthier alternatives to cigarettes. They contain nicotine but none of the other noxious chemicals in cigarettes. They may be useful in helping adults quit smoking, but I’m skeptical of that one. Why create a billion-dollar industry that’s sole purpose is to lose customers? But the operative word was adult.

The concerns are that vaping devices use flavored juices that make them appealing to teens. Even those sold to kids without nicotine set the stage for taking the next step to a nicotine product. But are juices or flavored liquids safe to vape? I’ll update what I wrote two years ago on Thursday.

Research Update on Vaping

/in /by

Tin, aluminum, lead, and zinc: those are the metals that were found in the aerosol generated by various e-cigarette devices in a recently published study. Sounds like exactly what you want to inhale deep into your lungs, right?

Researchers in Maryland recruited volunteer vapers to test the liquid in the tank, the aerosol, and the remaining fluid in their e-cigarette tanks; 56 subjects provided their e-cigarette for analysis. Testing these metals is no easy task. All samples were collected in sterile conditions, and all tests were compared to samples known to be pure and also with calibrating liquids. The objective was to see what contributions the heating coil might have made to the metals in the aerosol.

Levels of tin, aluminum, lead, and zinc increased after exposure to the coil and the heat it generates, and that’s being distributed into the lungs. Did the metals all come from the coil? No, the e-liquid already had the metals, but the amounts increased after conversion to aerosol.

This adds to the growing body of research that suggests vaping is not benign and is potentially harmful. We won’t know how harmful for years, possibly decades, when those who began vaping years ago are tested and found to have higher rates of lung disorders. If you continue to vape, you may look forward to being one of those subjects. It’s your body. It’s your choice.

The Bottom Line on E-Cigarettes

/in /by

The logic behind the use of e-cigarettes is that they’re better than traditional cigarettes and that vaping will help people quit smoking. Let’s take a look.

The major benefit attributed to e-cigarettes is less exposure to toxic chemicals resulting in fewer harmful effects. In a few of the studies on chemicals found in the nicotine liquid, some metals such as cadmium, aluminum, and nickel were identified as well as the expected ingredients such as glycol and polyethylene glycol from glycerin usually found in e-cigarette liquid as a propellant (1). We don’t know whether they . . .

The Safety of E-Cigarettes

/in /by

One of the purported benefits of e-cigarettes is the decrease in exposure to harmful chemicals found in regular cigarettes. It makes sense to avoid the chemicals that could be found in the soil and on the tobacco leaves. Harvesting and processing won’t remove those from tobacco products.

The problem is that we just don’t know, because the liquids that contain the nicotine are not tested for safety. Many brands add flavorings to the liquid. While fruits may seem to be great flavors, when the juice is burned, the by-products may not be healthy even if sourced . . .

What Is Vaping?

/in /by

Last week’s message on smoking resulted in several questions about electronic cigarettes, a subject I haven’t addressed before. Let’s start with the basics.

An electronic cigarette or e-cigarette is a nicotine-delivery system. There are three essential components: the nicotine source, a heat source used to vaporize the liquid source of nicotine, and a power source in the form of a battery. The last two are pretty straightforward. The heat has to get high enough fast enough to vaporize the fluid quickly, hence the term vaping instead of smoking.

The nicotine source provides the drug. That . . .
