Cannabis: for some, it’s a way to relax on the couch, for others, a medicine that restores quality of life. More and more, we hear that cannabis is more than just a recreational drug.
But what does the science really say? Can cannabis really help with pain, insomnia, or even neurological diseases? In this blog, we dive into the medical story behind cannabis—in an accessible yet well-founded way.

Cannabis Is More Than Just for Recreation
Let’s start with the big question: is cannabis medicinal or not? The short answer is: yes, but not just any kind, and not for every issue.
Since the 1990s, scientists around the world have been researching the effects of cannabinoids, the active substances in cannabis, such as THC and CBD.
The idea of smoking a joint instead of taking a pill may sound rebellious, but in countries like Canada, Germany, and several U.S. states, medical cannabis has long been legally available. And we’re not talking about the weed you buy at a coffeeshop, but standardized products with precise compositions.
Still, this knowledge ultimately benefits everyday consumers as well. The more we understand about how cannabis works in the body, the better informed choices you can make—even as a recreational user.
What Is Medical Cannabis, Exactly?
“Medical cannabis” isn’t a magic word or label you can just slap on any weed plant. It typically refers to cannabis (products) that are:
- controlled for composition (THC/CBD ratio)
- available in fixed dosages
- proven effective for specific conditions
The two main players in the story are:
THC – known for causing the ‘high’, but also acts as a painkiller and muscle relaxant.
CBD – non-psychoactive, but calming, anti-inflammatory, and anxiety-reducing.
THC and CBD can enhance each other’s effects—a kind of teamwork where the whole is greater than the sum of its parts.
Pain, Sleep, and MS: What the Research Says
Let’s unpack some commonly heard claims and compare them to what science actually says.
Chronic Pain
A study by Ware et al. (CMAJ, 2010) showed that patients with neuropathic pain experienced 30% less pain after inhaling THC-rich cannabis. Not everyone responded equally, but the effect was significant—especially in people who don’t respond well to conventional painkillers.
Muscle Disorders like MS
Zajicek et al. (Lancet Neurology, 2003) conducted a double-blind study on patients with Multiple Sclerosis. The result? A clear reduction in muscle spasms and stiffness after using cannabis extracts.
Sleep Issues and Anxiety
A more recent study by Shannon et al. (Permanente Journal, 2019) explored the effects of CBD in people with anxiety and sleep problems. 79% reported less anxiety and 67% slept better after a month of use—without the ‘stoned’ feeling of THC.
These are not small numbers. But… we should be cautious about drawing broad conclusions. Not all cannabis strains work the same, and not every issue disappears overnight.
It’s Not All Sunshine and Smoke Clouds
Okay, so cannabis has medical potential. But that doesn’t mean it works everywhere, always, or is safe for everyone. A few caveats:
- Side effects may include: dizziness, dry mouth, reduced concentration—especially with THC.
- Long-term and heavy use (especially at a young age) may affect memory and mood.
- Self-medicating is risky: without proper dosage or medical supervision, you could easily under- or overdose.
That’s why products in the medical field are standardized. For recreational use, it’s crucial to get to know your body well and start with small amounts.
Can a Coffeeshop Write About Medical Cannabis?
Good question! Coffeeshops are not allowed to make medical claims—and we don’t. What we do share are insights from scientific research. Information that helps you, as a visitor, engage with cannabis in a more conscious way.
Especially in times when more people are wondering, “What does this actually do in my body?” … it’s valuable to separate facts from myths.
We don’t promote medical treatments. But we are fans of well-informed customers—because they often enjoy the product more, too.
