On May 14th, 2 different samples were tested using the FTIR Spectrometer at Overdose Prevention Society OPS in DTES Vancouver.
The substances of suspected 'down' were in grey chunk and orange paste form.
Both samples tested positive for fentanyl and benzo's by test strips. The Spectrometer showed Caffeine, erythritol, lactose for the Orange sample and Caffeine and Mannitol for the grey sample.
Both substances were purchased in the DTES and side effects for both showed results of extreme sleepiness and lethargy. People who had ingested this were very hard to rouse.
