The estimation of drug trade in the Czech Republic was made from the demand side, which is based on drug consumption. The first step is based on the estimation of drug users and their consumption in quantities (grams, pieces) by the main drugs used in the Czech Republic (cannabis drugs, pervitin, cocaine, ecstasy, LSD, heroin). The next step is the estimation of where the drugs are coming from (domestic production, import, export of domestic production) with use of drug purities. The final estimate is the use of drug prices (wholesale, retail) and the conversion of physical indicators into financial indicators, which are possible to use in the system of national accounts (production, intermediate consumption, export/import, final consumption of households, trade margin). It is then possible to estimate the value added, which is comparable figure with GDP. If the drug trade will be included in the national accounts (from 2011), then value added from drug trade in the Czech Republic will be 0.2 % of GDP. A specific calculation was made for the region Prague.
