Medical Cannabis
What the research actually supports, condition by condition, and what it does not.
Every page below reads the printed lab panel on a medical cannabis product and weighs it against a diagnosed condition, with each claim tiered and sourced. Every one also says plainly what the research does not support, which is the part no one else in the category prints.
Every condition is scored twice, because they are two different questions. Cannabinoid is the evidence for cannabis compounds like THC and CBD. Terpene is the evidence for the aroma compounds Terpenology actually reads off your product's label. When a card shows a strong cannabinoid tier next to a weak terpene one, it means cannabis as a drug has a real case for that condition while the specific thing we measure does not. That gap is the honest part, and we show it instead of hiding it.
Serious medical conditions you can be certified for in Pennsylvania. Other states keep their own lists; the terpene chemistry on your label reads the same everywhere.
Anxiety is the one condition where an isolated cannabis terpene has been tested in humans under controlled trial conditions, and the result is far more interesting, and far narrower, than the way it usually gets repeated.
Fit confidence: Low to moderate
PA qualifying conditionCannabis has real, FDA-recognized human evidence in cancer care, and it is entirely about easing nausea and appetite, not about treating the cancer.
Fit confidence: Moderate, and only for symptom support
PA qualifying conditionPain has the strongest case for medical cannabis of any condition we have reviewed, and thin evidence for the part of it we actually measure.
Fit confidence: Low to moderate
PA qualifying conditionThe best trial we have says cannabis made Crohn's patients feel meaningfully better and did nothing measurable to their inflammation.
Fit confidence: Low
PA qualifying conditionEveryone knows CBD is FDA-approved for seizures, and almost everyone misreads what that means.
Fit confidence: Very low, with a hard safety caveat
PA qualifying conditionMultiple sclerosis has some of the strongest human cannabis evidence of any condition here, and none of it is about the terpene profile your label shows.
Fit confidence: Low
PA qualifying conditionNerve pain has human cannabis trials behind it, and they are more tempered than the headlines suggest, and the terpene evidence underneath is thinner still.
Fit confidence: Low to moderate
PA qualifying conditionPTSD is a qualifying condition in Pennsylvania, and it is also the place where the honest answer is hardest to sit with: the best controlled trial of cannabis for PTSD found it worked no better than placebo, and no terpene has ever been tested for it at all.
Fit confidence: Very low
PA qualifying conditionEven the cannabinoid evidence for Parkinson's is weak enough that the Parkinson's Foundation declines to endorse cannabis for motor symptoms, and the terpene evidence is entirely in mice.
Fit confidence: Very low
Not named on Pennsylvania's list on their own; patients often qualify through a related condition such as anxiety or severe chronic pain.
This is the one condition page where the most useful thing we can tell you is a warning.
Fit confidence: Low
Related conditionThe interesting diabetes result is real, and it is about a minor cannabinoid, not a terpene, and it has not been repeated.
Fit confidence: Insufficient; preclinical only
Related conditionFibromyalgia has a handful of small cannabis trials that mostly disagree with each other, and zero terpene evidence of any kind.
Fit confidence: Low
Related conditionLupus is the clearest case in this whole series of a condition where the honest answer is that there is no answer yet.
Fit confidence: Insufficient evidence
Related conditionMenstrual cramps are the one women's-health use with even a modest real-world human signal, and it comes tangled up: every human study mixed the terpene in with CBD and THC, so no one can say the terpene did the work.
Fit confidence: Low; symptom support only
Related conditionWhat women mostly use cannabis for in perimenopause is sleep and mood, and what the research offers is a single survey and a stack of borrowed preclinical claims.
Fit confidence: Low; symptom-routed only
Related conditionRheumatoid arthritis has the best-supported terpene rationale of the autoimmune conditions we reviewed, which mostly tells you how thin that bar is.
Fit confidence: Low to moderate
Terpenology is educational, not medical advice. Terpene effects are tendencies commonly reported by patients and early research, never guaranteed outcomes. Nothing here is a substitute for the care of your certifying physician, your pharmacist, or the specialist treating your condition.
