cbd research - cannabis research

Part of why doctors remain wary of cannabis medicine is the lack of randomized, double-blind, placebo controlled trials — the gold standard for medical research. Because of cannabis’ status as an illicit drug, research is often relegated to retrospective surveys, which are useful but more likely to be biased. But there are methods in between these two schemes, such as open-label trials.

CBD for organ transplants

Candidates for organ transplant are thoroughly screened, and illicit substance use is usually disqualifying. But cannabis is well established as a medicine (as it has been for millennia) and should not prevent patients from receiving a necessary transplant. Doctors at a pediatric hospital in Delaware recently described the thought process around allowing or prohibiting cannabis use.

Pesticides on cannabis

Organophosphates are a class of insecticides like chlorpyrifos and soman. Sarin, used as a chemical weapon, is also an organophosphate. Many of these are neurotoxic, owing to their ability to amplify the neurotransmitter acetylcholine, which paralyzes insects and causes their death. A recent study from medical researchers in Maryland and Pennsylvania described the human toxicity in detail and explained why cannabinoids may be protective for humans.
