In clinical research, cannabis is often set up to fail. Federal restrictions privilege studying isolated molecules from cannabis over the plant itself. And even when cannabis research is done, scientists are often forced to use low-quality weed from the National Institute of Drug Abuse.
Preclinical studies are supposed to provide precise, controllable, and translational models for human diseases. But the manipulations that researchers use — like injecting a precise dose of THC into a rat — may sometimes miss important points. What if smoking and injection have different effects? How might this bias results? University of Florida researchers asked just that question, studying the effects of injected vs. smoked THC in rats. Injecting low doses of THC impaired memory.
Scientists from the Netherlands recently published the protocol for an upcoming study examining how CBD might be helpful in treating specific phobias. The endocannabinoid system is required for eliminating fearful memories, or at least making them palatable. But why have they only published their methods?
Nonsteroidal antiinflammatory drugs (NSAIDs) are one of the most common classes of painkillers, which includes aspirin, ibuprofen, celecoxib, and other pharmaceuticals. Their primary target is an enzyme called cyclooxygenase-2 (COX-2), which metabolizes many lipids (including endocannabinoids!) into a class of inflammatory molecules called prostaglandins.
Alan was disoriented and his words were not making sense. His wife thought he might be having a stroke, so she took him to the emergency room where he was seen by the on-call neurologist. When asked, Alan admitted to using cannabis on a regular basis for many years.
