08 Jul The Evolving Clinical Efficacy of Cannabidiol for Chronic Pain and Patient Access in Australia
Cannabis/CBD Notice: Cannabis products are not FDA monitored or approved. Discuss your use of medicinal cannabis or CBD products with your healthcare provider before use. Dosing is variable and products may interfere with other medications, stimulants and alcohol. Do not use cannabis or CBD products if you are pregnant, nursing, or may become pregnant. Do not use cannabis products when driving or operating difficult or dangerous machinery. Keep out of reach of children. Children and pets should not be exposed to cannabis or CBD products.
Chronic pain continues to be a complex challenge in modern medicine, driving significant research into non-opioid alternatives. Among the most closely monitored developments is the clinical application of cannabidiol (CBD). In Australia, the intersection of evolving clinical efficacy data and highly regulated patient access frameworks presents a fascinating case study in modern pain management.
For broader context on why medicinal cannabis is attracting clinical attention globally, see this overview of five reasons it is used for pain management, as well as this deeper look at how cannabinoids interact with the endocannabinoid system.

MedicalResearch.com: What is the background for this study?
Response: Smoking and tobacco use remains a major health issue. Smokers use cigarette over the course of the day because the levels of nicotine, the addictive agent in cigarettes and other forms of tobacco, dimmish with time in the bloodstream due to the breakdown of nicotine by enzymes in the body. By inhibiting the breakdown of nicotine in smokers, one would expect that the levels of nicotine would remain higher after smoking a single cigarette, and that these individuals may not require lighting up another cigarette so quickly, reducing the number of cigarettes smoked over the course of a day. This could have a profound effect on reducing the overall harm incurred from smoking or from using other forms of tobacco.
In a single previous study, smokers who used a CBD inhaler exhibited a 40% reduction in cigarette use. In addition, while cannabis users are often smokers, previous studies have indicated that they smoke less cigarettes than non-cannabis-using cigarette smokers. In previous studies published in 2021, we found that major cannabinoids present in cannabis like THC and CBD inhibit major metabolizing enzymes in our body, including several that are important in drug metabolism. We hypothesized that CBD and its major active metabolite, 7-hydroxy (OH)-CBD, may also be inhibiting one or more of the enzymes important in the metabolism (or breakdown) of nicotine.
