This thesis describes in the form of a commentary on own original publications research on the problems of cannabinoids, ie. phytocannabinoids and some synthetic cannabinoids, their pharmacokinetics and effects. The work consists of four thematic areas: the pharmacokinetics of delta-9- tetrahydrocannabinol (THC) and cannabidiol (CBD) in rats, depending on the route of administration; THC concentration time profile in humans (after inhalation) and implications for transport safety; the pharmacokinetic profile of synthetic cannabinoids in rats; extraction and determination of phytocannabinoids in plant material. The first part of the thesis was to determine pharmacokinetic profiles of THC, CBD and combination thereof (1:1 weight ratio) in rats with respect to administration common in humans, i.e. inhalation, oral and subcutaneous administration. THC, its metabolites (11-hydroxy-tetrahydrocannabinol, 11-OH-THC; 11-nor-delta-9- carboxytetrahydrocannabinol, THCOOH) and CBD concentrations in serum and brains of animals were monitored at the 24 hours experimental interval during the study. Except for inhalation administration, co-administration of CBD inhibited THC metabolism (after both oral and subcutaneous), resulting in an increase in THC concentrations in both serum and brain of the rats relative to...
