Increase in cannabis pollen linked to illicit growth in Spain

A study of the levels of atmospheric cannabis pollen in Murcia has detected a significant increase in recent years—indicating that illicit crop production has increased.

Researchers from the Polytechnic University of Cartagena in Spain have come to an interesting conclusion. Recently, the amount of cannabis pollen in the air has increased dramatically. It is not unreasonable to postulate, as the polytech scientists have now done, that the total amount of illicit cultivation in the region has increased significantly in the last four to five years.
