Between 2006 and 2019, blotter papers seized by police in Rio de Janeiro State, Brazil, were chemically and geographically mapped. Before 2014, most contained LSD and were concentrated in the metropolitan region. From 2014 to 2017, NBOMe-family compounds became dominant during a surge in seizures. NBOH compounds first appeared in 2016 in coastal tourist areas, with over 1300 items seized in 2017 alone. Only one synthetic cannabinoid was found. The most common new psychoactive substances were synthetic phenethylamines from the 25I-NBOH and 25I-NBOMe families. Chemical and statistical analyses revealed shifting drug profiles and movement patterns across the state.
