Recent information from various sources suggests that a new illicit drug, called ‘‘oxi’’, is being spread across Brazil. It would be used in the smoked form and it would look like to crack cocaine: usually small yellowish or light brown stones. As fully released in the media, ‘‘oxi’’ would differ from crack cocaine in the sense that crack would contain carbonate or bicarbonate salts whereas ‘‘oxi’’ would include the addition of calcium oxide and kerosene (or gasoline).

In this context, this work presents a chemical profiling comparative study between ‘‘oxi’’ street samples seized by the Civil Police of the State of Acre (CP/AC) and samples associated with both international and interstate drug trafficking seized by the Brazilian Federal Police in Acre (FP/ AC).
The outcome of this work assisted Brazilian authorities to stop inaccurate and alarmist releases on this issue. It may be of good use by the forensic community in order to better understand matters in their efforts to guide local law enforcement agencies in case such claims reach the international illicit market.
