Between 2011 and 2017, blotter papers seized in Santa Catarina, Brazil, increasingly contained a wide variety of new psychoactive substances (NPS) rather than LSD alone. In 2011, all blotters contained LSD; by 2014 only 0.1% did, and by 2017 LSD was found in 17.6% of blotters, while up to 25 different substances were detected. These included DOx, NBOMe, fentanyl, mescaline derivatives, triptamines, cathinones, and synthetic cannabinoids, sometimes mixed in a single blotter. The number of seizure events rose from 87 in 2011 to 301 in 2016 and 277 in 2017. The shift may reflect that many NPS were not illegal under Brazilian law when they first appeared.
