Notes:

1. The trends represent the available information on national potency / purity for each drug in the EU Member States, Croatia and Norway, weighted by country population sizes to form an overall EU trend. All series indexed to a base of 100 in 2005.

2. Countries missing drug price information for two or more consecutive years are not included in the trend calculations: the trend for amphetamine on twenty countries (68 % of the EU population 15-64), cocaine on twenty-three countries (83 % of the EU population 15-64), ecstasy on nineteen countries (70 % of the EU population 15-64), herbal cannabis on fourteen countries (58 % of the EU population 15-64), and cannabis resin on fifteen countries (57 % of the EU population 15-64). Trends for other drugs are not available due to insufficient data.

3. Additionally, where 2010 data are missing (one country) 2009 purity are used; for missing 2005 data (six countries) 2006 potency/purity data are used; data missing for other years (twelve countries) have been interpolated from adjacent years.
