THC exposure of human iPSC neurons impacts genes associated with neuropsychiatric disorders
Translational Psychiatry, April 2018
"In summary, we found significant associations of THC- related pathways to autism and intellectual disability. Furthermore, we have used a dynamic, human-relevant system to demonstrate a phenotypic link between THC treatment and schizophrenia. We hypothesize that THC exposure, by impacting many of the same synaptic and epigenetic pathways already associated with psychiatric disorders, may serve as an additive risk to existing genetic/ epigenetic risk factors."

Washington State Institute for Public Policy: "Advancing the Use of Evidence and Economics in State Government Policymaking Background Since the 1990s, the Washington State legislature has directed WSIPP to review research on “what works” (and what does not) in public policy. WSIPP’s work has spanned many topic areas, including criminal justice, education, child welfare, behavioral health, workforce development, public health, and prevention. In our systematic reviews, we assess the research evidence to identify public policies that improve statewide outcomes of legislative interest; we then estimate the benefits, costs, and risks associated with different options. This has become WSIPP’s standard approach to benefit-cost analysis." See additional resources here.
