What they claim to be "Objective and scientifically sound descriptions of internationally controlled drugs are available on the EMCDDA website in the form of ‘drug profiles’ in German, English and French".
Have not really had a chance to look at these yet, but profiles are available for Amphetamine, Cannabis, Cocaine/crack, Heroin, MDMA and Methamphetamine at the following link:
In their own words:
"Presented in a standardised way, the brief descriptions present the chemistry, pharmacology, synthesis and precursors of the six substances as well as their analysis, physical form (e.g. powder, tablet) and mode of use (e.g. ingested, snorted, injected).
The descriptions also contain sections on prevalence, street price and typical levels of purity, which will be updated annually on the basis of information provided by the Reitox network (2). Brief information on the possible medical uses and the exact control status of the substances, as well as ‘street names’ and selected images, complete the package."
