Among these, 10 states further permitted retail sale to provide a legal supply to adults. This study examined the associations of cannabis exposures with recreational cannabis legalization and commercialization. DESIGN Secondary data analysis of state-quarter level cannabis exposures during 2010-17 in the United States. Linear regressions with a difference-in-differences design were used to compare pre- and post-legalization trends in states that legalized recreational cannabis to contemporaneous trends in states that did not legalize recreational cannabis. SETTING United States, including all 50 states and DC. CASES Cannabis exposures reported to the US National Poison Data System. MEASUREMENTS The primary outcome was state age-adjusted cannabis exposures reported to the US National Poison Data System per 1 000 000 population per quarter. The two policy variables of interest included res with medical consequences than those without medical consequences (4.09-4.79 versus 0.97-1.01 more exposures). CONCLUSION An increase in cannabis exposures reported to the US National Poison Data System was observed following recreational cannabis commercialization in the United States. © 2020 Society for the Study of Addiction.Superatoms have been investigated due to their possible substitution for other elements. -phase synthesis of superatoms has attracted attention to realize the availability of superatoms. However, the previous approach is basically limited to the formation of a single cluster. Here, superatoms are investigated and the number of valence electrons in these superatoms is changed by designing the number of gallium atoms present. Based on the dendrimer template method, clusters consisting of 3, 12, 13, and other numbers of atoms have been synthesized. The halogen-like superatomic nature of
