As cannabis finds its place back into modern human culture quickly, there is much still to be learned. As the science grows and adapts to modern need and expectations, the “can we” may be out-pacing the “should we.” On the other hand, there are circumstances where modern culture really “should be” and is handicapped by years of misinformed stigma.
Here, a few controversial questions about cannabis:
Should teachers be allowed to use cannabis around children?
Should spiritual leaders be allowed to use cannabis, as they have for millennia?
Should taxi drivers be allowed to use cannabis on the job?
Should pilots be allowed to use cannabis?

Title:Preferences for Medical Marijuana over Prescription Medications Among Persons Living with Chronic Conditions: Alternative, Complementary, and Tapering Uses
In a survey of 30 patients using medical cannabis for a range of diseases including rheumatoid arthritis, cancer, hepatitis C, PTSD, among others, patients reported an array of benefits they have reaped from cannabis use. Patients successfully used cannabis in several ways: as an alternative to prescription medication, complementarily with prescription medicine, and to gradually replace use of prescription medication.
Benefits described by participants included the effects of cannabis lasting longer than that of opioids, lower risk of addiction, fewer side-effects. Patients also saw their sleep, anxiety, appetite, and adverse reactions improve with the use of medical cannabis. Larger, more controlled studies may suggest cannabis more affirmatively as an alternative or complementary therapy with prescription medications.
Title: Neuroanatomical alterations in people with high and low cannabis dependence
A recent article has been published revealing some volumetric alterations in specific brain regions in people who report dependence on cannabis. Magnetic resonance imaging revealed that the volume of certain regions, including the hippocampus, the cerebellum, and the caudate, in cannabis dependent users, were all reduced in size, relative to recreational cannabis users who did not use cannabis chronically. Future research will likely focus on the effects of the structural alterations on patients’ reward, stress, and addiction-relevant circuitry to examine the possible relevance of cannabis dependance on those circuits.
There are certainly possibilities that suggest this volume difference could be of concern, but there are also a great number of explanations (more than likely) whereby this is related to another variable that we have not yet fully appreciated.
Currently, cannabis use is thought to have a little-to-no risk of addiction (beyond any “normal” product of medical value, such as coffee or eyeglasses), because it does not act directly on the reward circuit. Opioids have a high risk of addiction, and therefore a concerning safety profile, in part because of the direct effect of the opioid system on the reward pathway of the central and peripheral nervous systems. While the endocannabinoid system has been observed to act directly up the reward circuit, it does so in subtle, soft ways, making it an ideal adjunct therapy for opioids to help with pain management. Current research provides inconsistent results and appropriately emphasizes a need for more testing to validate the possibility of cannabis as a recommended pain medication.
Impacts of cannabinoid epigenetics on human development- reflections on Murphy et. al. ‘cannabinoid exposure and altered DNA methylation in rat and human sperm’ epigenetics
An op-ed has praised the work published last year which exposed how pre-conception exposure to cannabis in males is related to alterations in epigenetic regulation of the central nervous and immune systems. Murphy et. al.’s paper ‘Cannabinoid exposure and altered DNA methylation in rat and human sperm,’ revealed that the sperm cells of men who have consumed cannabis are a key vector that may affect neuraxis, heart blood vessels, immune stimulation, secondary genomic instability, and carcinogenesis in the fetus offspring. The author of the response piece extrapolates the data collected by Murphy et. al. to conclude the genome-epigenome is extremely sensitive to environmental toxicants and that further research should examine the epigenomic toxicology of multiple cannabinoids.
The effect of prenatal exposure to cannabis on birth rates, birth outcomes, and the health of the mother is still uncertain. Studies focussing on cannabis use during pregnancy are limited, and what little has been reported, is inconsistent. The featured article now brings to light that bothparents may need to be cautious when attempting to conceive or when having unprotected sex as cannabis may affect both germ cells. Currently, governing bodies of obstetricians advise that pregnant mothers cease any cannabis use so if someone who needs cannabis for a medical purpose that improves their quality of life becomes pregnant they need to seek out alternative methods of treatment. Research is needed so that pregnant women can safely continue their medication or so that alternatives can be found so that women do not need to suffer for the duration of their pregnancy and possible breastfeeding period.
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:
