Patient questions, answered by a physician.
“Does ingesting cannabis nano emulsions effect nitric oxide production”
We do not currently have human studies showing that cannabis nanoemulsions directly increase or decrease nitric oxide production.
Clinical research indicates that cannabinoids do not "cure" PTSD or reliably lower total PTSD severity scores across the board, but they can offer targeted temporary relief for specific symptom clusters like traumatic nightmares, sleep disruption, and intense hyperarousal.
Cannabis compounds often produce what pharmacologists call a "biphasic effect," meaning low doses and higher doses can produce opposite reactions in the body.
“Is THCV truly an appetite suppressant? Why isn't it all over the market?”
While early research suggests tetrahydrocannabivarin (THCV) may reduce appetite in some contexts, the evidence is not yet strong enough to call it a reliable or proven weight-loss tool.
“I have a root canal coming up and someone suggested taking CBD beforehand to calm my nerves and help with the pain after. Does that work?”
The one trial that tested exactly this did not find a benefit.
“I am starting chemotherapy next month and I am already nauseous just thinking about it. Does cannabis actually help with that, or is it wishful thinking?”
For nausea that persists despite standard anti-sickness medicine, there is real evidence it helps.
“Does medical cannabis help with cancer pain and the general awfulness of advanced cancer?”
This is a very tricky question - with answers that keep changing with different papers and patient reports.
“Is there any evidence for cannabis helping tics in Tourette syndrome? My son has tried a lot of medications without much luck.”
There is, from a small but carefully designed trial.
“My father has Parkinson's and keeps reading that cannabis helps with tremor. Is there anything behind that?”
For now, less than the enthusiasm suggests.
How we cite research
Every study linked on this page is checked against PubMed so the link goes to the paper it names. If a study can no longer be verified, any answer relying on it is taken down until a physician reviews it again. Software can confirm that a citation is real. It cannot confirm that a study supports what we wrote. That judgment belongs to our reviewing physicians.

Navigating the Stigma as a Senior
“At 68 years old, I never thought I’d be considering cannabis as part of my treatment. My generation didn’t grow up viewing it as medicine, we saw it as something entirely different. But after dealing with arthritis pain for over a decade, my daughter encouraged me to give it a try. Meeting with a professional who truly understood both the science and the hesitations I had made all the difference. Dr. Caplan explained the endocannabinoid system in a way that made total sense. Today, I’m sleeping through the night and gardening again without chronic joint pain.”
Reclaiming Life with Holistic Care
“I had been living with chronic fatigue and pain for years, feeling like I was just existing rather than living. Traditional medicine had brought little relief, so I started looking into alternative options. Working with a doctor who truly listened to my struggles and offered a holistic approach to care was a game-changer. The cannabis regimen we developed not only improved my energy levels but also allowed me to engage in activities I hadn’t been able to enjoy in years.”
A Patient’s Guide to Finding the Right Dose
“My journey with cannabis therapy was not a straight line. When I first started, I thought one dose or product would fix everything, but I quickly learned it’s a process of trial and adjustment. Working with a knowledgeable doctor made all the difference. We started low and slow, as they say, and I kept track of how I felt each day. Over time, I found the right balance that worked for my condition without feeling overwhelmed.”
Finding Balance After Postpartum Anxiety
“After having my second baby, I struggled with severe postpartum anxiety. It was difficult to admit I wasn’t feeling okay. Traditional treatments left me feeling disconnected, and I didn’t want to spend my days like that. When I started exploring medical cannabis, I was cautious but hopeful. Meeting with Dr. Caplan helped me approach it with confidence. Low-dose CBD and microdosing restored my calm and allowed me to be fully present for my children.”
Overcoming My Fear of Cannabis Therapy
“For years, I hesitated to explore medical cannabis. I had so many misconceptions, fear of side effects, worries about legality, and embarrassment about what others might think. But after years of struggling with chronic anxiety and sleep disruption, I decided it was time to explore new options. Meeting with Dr. Caplan completely shifted my perspective. He helped me understand that cannabis wasn’t about masking symptoms; it was about restoring biological balance.”
