Cannabis resin seizures indicate a contracting market, as cannabis herb (with high levels of THC) is increasingly replacing cannabis resin.

• Cannabis resin seizures showed an upward trend until 2020 but have since fallen sharply across all regions – by more than 50 per cent globally – pointing to a contraction in the resin market.
• Seizures remain concentrated in Western and Central Europe, North Africa and the Near and Middle East/South-West Asia subregions. However, seizures in North Africa (notably Morocco) overtook those reported in Western and Central Europe in 2024, mainly reflecting increased resin seizures in Morocco and declining seizures in France, Italy, Portugal and Spain as well as in some North African countries.
• The patterns are less clear for South-West Asia where cannabis resin seizures rose in Pakistan but declined in Afghanistan and in the Islamic Republic of Iran.
• Over the longer term, cannabis herb has increasingly displaced resin across many regions, including Europe and North America, likely driven by the expansion of high-THC indoor production. This shift is reshaping markets and trafficking patterns, although resin remains dominant in specific areas such as the Iberian Peninsula due to geographic proximity to major production zones and in the Scandinavian countries.
