Published on: 

In this roundtable interview series, we speak to each of the organizers of the CannMed Medical Practicum to learn more about them and what attends can expect from the practicum. Here in part I, they share some of the clinical applications for medical cannabis and dosing information.

Founded in 2016 by Medicinal Genomics, the upcoming CannMed conference—recently rescheduled for May 3–5 in Pasadena, California—will feature an exciting full-day CannMed Medical Practicum organized by Bonni Goldstein, MD, (the practicum’s originator); Dustin Sulak, DO; Kevin Spelman, PhD, MCPP; and Eloise Theisen, RN, MSN, AGPCNP-BC. During this practicum, each of the presenters will share the latest research, their clinical experience, and practice guidelines related to cannabinoid therapeutics, inclusive of types of extractions, products, and optimal dosing of cannabinoids for various therapeutic scenarios. This course is approved by the California Board of Registered Nursing for 9.5 contact hours.**

In this roundtable interview series, we speak to each of the organizers to learn more about them and what attendees can expect from the practicum. Here in part I, they share some of the clinical applications for medical cannabis and dosing information.

What are some of the clinical applications for medical cannabis?

Bonni Goldstein, MD: Medical cannabis can be useful for numerous conditions, including managing symptoms of neurodegenerative disorders, inflammatory gastrointestinal conditions, symptoms from cancer and cancer treatment, chronic pain, sleep disorders, and some psychiatric disorders. Because of the widespread distribution of the cannabinoid receptor, we know that the endocannabinoid system plays a role in almost every physiologic process and therefore can be utilized as a target for treatment.

Kevin Spelman, PhD, MCPP: Anxiety, seizure disorders, pain, mood disorders, sleep issues, and autoimmune disorders.

Dustin Sulak, DO: Chronic pain, insomnia, PTSD, nausea, and vomiting are certainly the most common, but a typical cannabis practice is full of refractory conditions from every other field in medicine, for example, psychiatry, gastroenterology, oncology, neurology, rheumatology, and so forth. Overall, cannabis is often an effective treatment when everything else has failed.

Eloise Theisen, RN, MSN, AGPCNP-BC: According to the National Academies of Sciences, Engineering and Medicine report on the health effects of cannabis and cannabiniods, there is moderate to substantial evidence to support the use of cannabis for chronic pain in adults, sleep disorders, chemotherapy induced nausea and vomiting, and muscle spasms in multiple sclerosis. Additionally, we are seeing more clinical data to support the use of cannabinoids for anxiety, depression, and PTSD.

How is medical cannabis dosed and what methods are being used by patients?

Bonni Goldstein, MD: Medical cannabis is different than most pharmaceutical medications, meaning there are no specific dosing recommendations for the vast majority of conditions being treated. Patients are advised to “start low and go slow” to customize their dosing regimen. The reasons for this include a wide inter-individual variation in absorption, metabolism, and excretion of the cannabinoids and other compounds in the plant. However, a clinician knowledgeable in cannabis dosing can help a patient negotiate dosing for the many products on the market, helping to personalize the patient’s dosing regimen. Methods of use include inhalation, ingestion, sublingual, topical and transdermal applications. Each of these has advantages and disadvantages that can help patients choose their preferred method, although many patients use multiple methods of use depending on symptoms, time of day and cost.


Kevin Spelman, PhD, MCPP: Dosing has a high interindividual variability. Best to start at very low doses and work up so the optimal "physiological" dose can be found (versus a "pharmacological" dose)

Dustin Sulak, DO: Cannabis is highly versatile and allows for individualized treatments that can often be fine-tuned to allow for all benefit and no adverse side effects. This fine-tuning includes delivery methods (oral, oromucosal, inhaled, topical), numerous varieties of cannabis with distinct properties. You can find more info at:

Eloise Theisen, RN, MSN, AGPCNP-BC: Cannabis is best when it is individualized to the patient's condition and goals of care. It is important to take a thorough health history and discuss the plan of care with the patient. Some patients may need low doses to achieve relief and others may need higher doses and that usually cannot be determined without considering many factors like age, gender, other health conditions, medications and previous or current cannabis experience. In some cases, patients may need multiple methods of administration to effectively treat their condition.
