Freeman, Tom P and Groshkova, Teodora and Cunningham, Andrew and Sedefov, Roumen and Griffiths, Paul and Lynskey, Michael T (2019) Increasing potency and price of cannabis in Europe, 2006‐2016. Addiction, 114, (6), https://doi.org/10.1111/add.14525.

European cannabis resin and herbal cannabis increased in potency and price from 2006‐2016. Cannabis resin (but not herbal cannabis) increased in the quantity of Δ9‐tetrahydrocannabinol per Euro spent. Marked increases in resin potency and value from 2011‐2016 are consistent with the emergence of new resin production techniques in European and neighbouring drug markets.
