The greatest challenge for European drug policies is how to effectively respond to the dynamic and constantly changing market for new psychoactive substances (NPS). Even small modifications in the chemical structure of substances often allow circumventing existing laws. Also in prison, the

Various cosmetic hair manipulations are known to interfere with drug of abuse concentrations in hair. It is important to evaluate the effects of cosmetic hair treatments as they can influence quantitative hair results. Only one study showed a significant decrease of THC after bleaching and coloring.

Saliva and sweat have been presented as two alternative matrices for the establishment of drug abuse. The noninvasive collection of a saliva or sweat sample, which is relatively easy to perform and can be achieved under close supervision, is one of the most important benefits in a

Although there is a vast literature on drug use and addiction, there is little work that addresses the long-term use of drugs within the general population. We take a more contextual look in examining longitudinal drug use patterns over the course of 14 years for a representative sample of young

BACKGROUND Trigeminal trophic syndrome (TTS) is an uncommon disorder of the trigeminal nerve tract and trigeminal brainstem nucleus.

Testing hair for cannabis use has increasingly been scrutinised due to exposure to second-hand smoke or environmental contamination. Confirmation of drug use involving detection of metabolites such as 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (THC-COOH) and
