New publication out now, in which we used an ultra‐high field multimodal brain imaging approach, and showed that in occasional cannabis users, acute THC administration increased striatal glutamate and decreased functional connectivity in the reward system, which were associated with increases in subjective high and decreases in sustained attention. Such changes were absent in chronic… Continue reading Reduced responsiveness of the reward system is associated with tolerance to cannabis impairment in chronic users
We are offering a research intern position for a master student who is interested in the therapeutic effects of cannabis. We will conduct a field study in which we will study impulsivity in cannabis users. Specific activities consist of contacting coffee shops, recruiting participants, collecting data by means of questionnaires and neurocognitive tasks, data management,… Continue reading We are looking for a research intern, for a study on the therapeutic effects of cannabis
New publication out now, examining the accuracy of two commonly used point-of-collection testing devices in detecting oral fluid THC. Tests were performed at fixed intervals over 3 hours, yielding a total of over 300 tests. Both devices produces a surprisingly high number of false positives and false negatives. By 180 min, all samples contained less… Continue reading Detection of Δ9 THC in oral fluid following vaporized cannabis with varied cannabidiol (CBD) content: an evaluation of two point-of-collection testing devices
Most street cannabis contains large quantities of THC, the chemical in cannabis that gets people ‘high’, but there is increasing use of medicinal products that also contain CBD, a non-intoxicating cannabinoid with promising therapeutically potential. It has often been proposed that administering CBD may reduce some of the impairment caused by THC. To test this,… Continue reading Cannabidiol (CBD) content in vaporized cannabis does not prevent tetrahydrocannabinol (THC)-induced impairment of driving and cognition.
