An aerobiological study sampling airborne Cannabis pollen at Tetouan in north-western Morocco over three years, using a Hirst type volumetric trap run continuously to the Spanish Aerobiology Network protocol. The authors record pollen in the atmosphere from early April to late August, with about 95 per cent of the annual count falling inside that period and the highest concentrations in June and July. They argue the data can serve as an indicator of the extent of cannabis cultivation in the region, and separately that the levels measured are high enough to matter clinically as an aeroallergen. Useful to the Rif cultivation record as a measure of cultivation activity arrived at independently of the UNODC survey series.
