“Older adults are at elevated risk of reducing labor supply due to poor health, partly because of high rates of symptoms that may be alleviated by medical marijuana. Yet, surprisingly little is known about how this group responds to medical marijuana laws (MMLs). We quantify the effects of state medical marijuana laws on the health and labor supply of adults age 51 and older, focusing on the 55 percent with one or more medical conditions with symptoms that may respond to medical marijuana. We use longitudinal data from the Health and Retirement Study to estimate event study and differences‐in‐differences regression models. Three principle findings emerge from our analysis. First, active state medical marijuana laws lead to lower pain and better self‐assessed health among older adults. Second, state medical marijuana laws lead to increases in older adult labor supply, with effects concentrated on the intensive margin. Third, the effects of MMLs are largest among older adults with a health condition that would qualify for legal medical marijuana use under current state laws. Findings highlight the role of health policy in supporting work among older adults and the importance of including older adults in assessments of state medical marijuana laws.”

“Diseases affecting the central nervous system (CNS) should be regarded as a major health challenge due to the current lack of effective treatments given the hindrance to brain drug delivery imposed by the blood-brain barrier (BBB). Since efficient brain drug delivery should not solely rely on passive targeting, active targeting of nanomedicines into the CNS is being explored. The present study is devoted to the development of lipid nanocapsules (LNCs) decorated with non-psychotropic cannabinoids as pioneering non-immunogenic brain targeting molecules and to the evaluation of their brain targeting ability both in vitro and in vivo. Noticeably, both the permeability experiments across the hCMEC/D3 cell-based in vitro BBB model and the biodistribution experiments in mice consistently demonstrated that the highest brain targeting ability was achieved with the smallest-sized cannabinoid-decorated LNCs. Importantly, the enhancement in brain targeting achieved with the conjugation of CBD to LNCs outperformed by 6-fold the enhancement observed for the G-Technology® (the main brain active strategy that has already entered clinical trials for the treatment of CNS diseases) As the transport efficiency across the BBB certainly determines the efficacy of the treatments for brain disorders, small cannabinoid-decorated LNCs represent auspicious platforms for the design and development of novel therapies for CNS diseases.”
“Substance use disorder is characterized by repeated use of a substance, leading to clinically significant distress, making it a serious public health concern. The endocannabinoid system plays an important role in common neurobiological processes underlying substance use disorder, in particular by mediating the rewarding and motivational effects of substances and substance-related cues. In turn, a number of
