Vaping

The Benefits and Limitations of Vaporization

A Qualitative Analysis of Cannabis Vaporization Among Medical Users

In Summary

Researchers have recently analyzed popular vaping behavior and revealed the advantages of vaporizing medical cannabis. The general advantages of vaporizing medical cannabis include portability, concealability, and efficiency, while the medical advantages like promoting tobacco cessation and it’s quick-acting effects. There are also limitations to vaporization, like technology-use barriers for those who find technology difficult to work with and the cost of such devices. Vaporizing may also prove to be advantageous or disadvantageous for patients depending on their medical condition, meaning that all patients should discuss consumption mechanisms with their physician. 

As the cannabis industry continues to grow various consumption methods become readily available for consumers, each presenting its own benefits and limitations. Patients should thoroughly research the different consumption methods and discuss which method would work best for them. Vaporizers in the featured article were mainly portable but desktop vaporizers are also available and often more efficient. The world of edibles continues to grow and it better for those looking for longer-lasting, stronger, and delayed effects. Tinctures are easy to prepare at home or buy online and are ideal for incorporating into patients’ favorite meals, smoothies, or can be taken sublingually for fast-acting effects and raw cannabinoids. Experimentation is encouraged, just be sure to start at a slow dose and slowly feel out the effects.

Are medical patients victims of #vapegate?

A popular (and welcome) take on the vaping situation is coming out to support medical consumers as a type of victim of the circumstances. There is a level of scientific understanding that is a necessary, and still incomplete, part of the discussion. For example, some of the dominant methods of lab testing for cannabis (plate culturing) are based on food safety protocols that are generations old, incorporates a system of understanding that is not the only means of testing or understanding (genetic sequencing, for instance) and, while we have learned a great deal mastering the current testing, we may be missing important safety concerns.

Another critical area of growth at hand is the clinical understanding of the implications of mainstream cannabis consumption. We have some information, but there is always more yet to learn. In order for Cannabis Medicine to catch up with the accomplishments and accolades of modern Medicine, we must overcome generations (and engrained systems) of academic road-blockages. Still more stands in the way of a well-oiled, safe cannabis-consuming culture, and that is reproducibility of clean product and the assurance that a consume is obtaining (and consuming) clean, safe product. These are solved, perhaps with regulatory oversight and technology, either within the public or private sectors.

For example, one of the elements of the current medical market that is still in need of close inspection and consideration is the potential contamination of vaporized products related to the construction materials of vapor technology itself. Devices are often made with metal solder which can contain and propel cadmium and/or other metals that are unhealthy for consumption. Similarly, heated plastics and other construction materials may be unsuitable as conduits for consumption by inhalation.

See https://www.cedfoundation.com/2019/09/05/vape-gate-2019-review-of-the-risks-of-vaping/ for a more complete review of some of these elements.

Nevertheless, it is wonderful to see public interest and discussion on this subject, which seems to touch on never common to many. Open-minded discussion, incorporating differing viewpoints will help us all grow to become a healthier and safer, cannabis-consuming culture.

Could Inhaled Cannabis Be More Effective to Relieve Pain than Oral Cannabinoids?

Cannabis for Chronic Pain: Challenges and Considerations

In Summary:

Comparisons between the use of inhaled cannabis plant versus pharmaceutical-grade oral cannabinoids demonstrate an advantage of inhalation over oral delivery. Conditions for which inhalation has provided superior over oral consumption include:

HIV, diabetic neuropathy, post-herpetic neuralgia, complex regional pain syndrome, spinal cord injury, traumatic neuropathic pain, multiple sclerosis, and cervical disk disease.

An important note: patients consuming cannabinoids orally are more likely to withdraw from studies due to negative side effects and lack of efficacy. Also, edible cannabis may compete, amplify, or have effects delayed, when interacting with other ingested foods and drinks, A major advantage of inhalation is the opportunity for patients to titrate, or easily test varying dosages at home, with reasonably rapid feedback. On the other hand, dosage adjustments for oral food-borne cannabinoids are much more complex, and cannabis in the form of oral pharmaceutical-products may require a doctor visit and a new prescription.

Dr. Caplan and the #MDTake:

In the clinic, there seems to be a great divide in the population, a group of patients who simply adore the edibles (often in low-dose candies, low-dose chocolate, or titrated tinctures), and a group who use inhalation, almost exclusively. There are also some who are discovering topicals (salves, patches, lotions). There is a growing number of patients who use each of these methods with intention, related to their timing of onset and their duration of action, but this requires education, practice, and a degree of sophistication in use that is relatively new to the industry.

As with most consumption, medicinal or not, it seems common for individuals to find a method that they enjoy and stick to it. Interestingly, in recent years, the US cannabis industry has evolved in a wild growth phase. As it has embraced a dynamic landscape, with increasing competition from all sides, including new stores and product offerings popping up all the time, there seems to be a growing openness, in consumers, to trying new products and exploring new offerings. Coincidentally, this openness to change and the unfamiliar happens to mirror one of the core neurobiological functions of cannabis in the brain, as seen across the neuropsychiatric and neuroimaging cannabis literature.

How exciting to imagine a future medicine that may help consumers to be more open to change?

Vape-Gate 2019: Review of The Risks of vaping

Risks on the Production Side of the Market:

  • Bacteria: Within facilities that lack appropriate oversight, any bacteria present during the manufacturing of a vaped product can be a source of risk for the consumer.
  • Fungus: Similarly, fungus can be a normal part of ambient air and life on earth, particularly around plants and soil. If production facilities do not have state-of-the-science monitoring or control mechanisms to limit mold, fungus can accumulate during the manufacturing process and can be transmitted to consumers.
  • Particles: Nicotine- or cannabis-containing products that are not produced in regulated facilities (home-grown and/or street-sold real or counterfeit products) may contain dangerous solvents, including solutions that contain lipid content that does not belong inside human lungs. Equally concerning, even in states with strict regulatory oversight over cannabis, the regulations may not cover particulate matter which may come into the consumer’s body from the containers that store tested cannabis products. For example, labs across the US have identified particles of vapor cartridge construction materials that become airborne during the heating process of vaporization. There is currently no testing standard for such circumstances. More, the sheer volume of particles emitted by a tool producing vapor is unregulated. With respect to its effects on the lungs, it is likely that there are meaningful differences (and potential risk differences) between a vaporizer which produces a small cloud of particles compared with one that produces a large, dense cloud.
  • Nicotine/E-liquids: Many nicotine vaporizers contain flavoring, coloring, preservative liquids that can be irritating to the lungs and breathing architecture. Non-nicotine liquid mixers can include sugary substances which promote dangerous growth of bacteria, inside the lungs.
  • Supervision: Street or home-produced products lack quality control measures to ensure that they are made safely, and/or contain safe ingredients, and are being delivered inside safe devices. In contrast, most FDA-overseen nicotine products and state-overseen cannabis production facilities limit many risk factors for currently-known threats to health

Risks on the Consumer Side of the Market:

  • Bacteria: Once purchased, products exposed to everyday life can acquire potentially dangerous bacteria after they are produced and sold. When used with poor maintenance practices, or by a consumer with hygiene practices that may add additional risk, bacterial infections can arise.
  • Fungus: Like bacteria exposure and potential infections, mold/fungus can accumulate after a vaping product is purchased. Good maintenance/cleansing practices help to prevent this risk, and appropriate hygiene around the consumption of vaping products typically minimizes this concern.
  • Particulate Matter: When using and re-using vaporizer tools (pens, vaporizer ovens, edibles), foreign particulate matter may break-off from cartridges, or may accidentally enter into products that were previously free of these contaminants. Many of the popular vaporizer cartridges, for example, seem to come from three facilities in China and are sold, worldwide, because of the attractive low price-point. Across the US, lab evidence has discovered evidence of small particles of the cartridges themselves (plastics, metals, other materials.) These particles can cause irritation to, or have toxic local effects on, the lungs. These reactions can certainly stimulate an inflammatory response which is sometimes equally uncomfortable as the offending irritation.
  • Coughing: Vaporizing a product which causes the user to cough excessively can risk the accidental aspiration of bacteria or particles from the mouth. These particles, if small enough, can cause inflammation or infection in the lungs.
  • Nicotine: In addition to the well-documented increased risk of cancer from the consumption of nicotine, this chemical is an irritant to the tissues with which it interacts, causing arterial wall constriction and thickening. It increases blood pressure and heart rate, promotes increased inflammation and suppresses normal immune system function. More, it also artificially elevates dopamine, norepinephrine, and acetylcholine, with poorly understood consequences that are unlikely to be healthy for the lungs.
  • Maintenance: Vaporizing old or poorly-kept products may ignore the very real effects of deterioration of materials which may pose health concerns. A product which is not well-maintained or regularly cleaned may contain infectious particles, irritating particles, toxic elements which may also be found in a pocket or storage container (insecticides, animal poisons, other chemicals which may preserve or protect during production or travel)

Individual Differences:

Between the production and the consumer sides of the vaporization arena, individual differences and outside influences can have a tremendous impact on the experience of vapor. Someone with a history of lung disease may tolerate a very different product than someone without such a history. Similarly, someone with a weakened immune system may have a more difficult time healing from an average exposure (to an irritant or an infectious particle) than someone with different circumstances. These are not likely to explain a large incidence of illnesses, but in addition to the concerns above, they may help explain a smaller portion.


Some of the Medical Illnesses Potentially Associated with Vaping:

1. Pneumonia (bacterial)

2. Aspiration Pneumonia

3. Idiopathic Acute Eosinophilic Pneumonia

4. Hypersensitivity Pneumonitis (extrinsic allergic alveolitis)

Typically this is related to the components of e-cigarettes: nicotine, propylene glycol/glycerol, ethylene glycol, any of >7000 flavorings, metals including tin, lead, nickel, chromium, manganese, and arsenic (have all been found in e-cigarette liquids), also nitrosamines common to tobacco, carbonyl compounds, volatile organic compounds, and phenolic compounds.


General Recommendations for Safer Consumption:

  • Use state-supervised companies, including dispensaries for cannabis-related vaporizer materials, and reputable nicotine suppliers
  • Convection vaporizer ovens that involve safe heating materials (ceramic, glass, quartz) are preferable to vaporizer cartridges.
  • Any means of detaching product from direct contact with a heat source is preferable. For example, stainless-steel containers that hold product, and are then placed into a heating chamber, is likely to be safer than placing product directly against heat.
  • Safe heating elements: chamber-based convection/conduction heating
  • Avoid direct contact with coils, and avoid combustion
  • Use fresh products from state-sponsored dispensaries or stores
  • Avoid products that are repeatedly reused (including vaporizer pens and vaporizer heating tools that stay full of organic material for more than a brief period of time
  • Prefer systems that include the opportunity to easily clean and replace individual used components
  • Use rubbing alcohol to clean any heating tools regularly

5 Benefits of Vaping Cannabis (vs smoking)

Within the inhalation method of consuming cannabis, there are many different ways one can inhale it.

The ancient way was almost always to smoke it. In the modern era of cannabis consumption, there are many more popular and advanced ways to consume either flower or concentrates:

  1. “Desktop” models that may use electricity for amplified power,
  2. Portable models that are more useful for inhalation-on-the-go,
  3. Cartridge-based “vape pens” to vaporize potent concentrates in a simple mechanism.

In short time, we will likely see adoption of (and a quickly massive rise in popularity of) aerosolization and nebulized cannabis consumption too!

Are the benefits of vaping strictly limited to cannabinoids? Certainly not.

Are the benefits of vaping even limited to terpenoids? Certainly not.

What else is there? Flavonoids.

And still more? Combinations of these that create entirely new results!

Cannabis: Vaporizing vs Smoking

Smoking cannabis brings toxins and unhealthy combustion byproducts into the body. With temps in the ~2000’F range for flame, burning flower incinerates a large portion of the product being consumed. As the distance from the point of flame grows, temperatures are lower, and cannabinoids are vaporizing, in addition to being burned by the flame. Over time, as heating technology has improved, there is no longer a need for blasting temperatures way beyond what the material can safely sustain before turning to tar and ash.

Beyond developed habits of consumption, social familiarity, and simplicity of use, one of the reasons many enjoy combustion is the other effects of heat. As with any human contact with extreme heat, blood rushes to the source of heat, and this may present a platform, through which cannabinoids may enter the bloodstream more quickly. The extravagant heat is also aerosolizing many more cannabis compounds than vaporization temperatures typically support, so the effect of flame is often felt to be more intense.

Vaporizing cannabis, however, is less likely to introduce mutations in the polyphenol compounds found in abundance within cannabis, and some of the mutations create terrible molecules known to be caustic and destructive.

If the medical rationale for vaporizing (over combustion) is not convincing, please consider the financial argument: Though purchasing a vaporizer may be costly, it’s a smart investment that could save money in the long run. Learn more by watching this video:

Consuming CBD with THC Decreases Systemic Availability of THC

Title: Model-based analysis on systemic availability of coadministered cannabinoids after controlled vaporized administration 

A new study revealed findings that vaporizing cannabidiol (CBD) with ∆-9-tetrahydrocannabinol (THC) lowers the systemic availability of THC.

Researchers analyzed the blood plasma level of CBD and THC in a randomized, double-blind study, and found that those who inhaled a high dose of CBD were found to have lower levels of THC. Frequent cannabis users were found to have only minorly decreased levels of THC in their plasma when high doses of CBD was coadministered. Future studies should be conducted to examine the validity of these results for other consumption methods. 

This work highlights how those who have consumed too much THC can combat some of the symptoms associated with THC by consuming CBD. Occasionally, cannabis users may overindulge in THC and feel anxiety, panic, or dizziness. One of the best ways to combat such overindulgence (and lower the effects of THC) is to consume a high dose of CBD. Other, non-cannabis related, methods are also commonly recommended, such as relaxation or food with high levels of the terpenes caryophyllene and limonene. When using cannabis it’s important to start low and go slow in order to minimize the possibility of overindulgence.
