ABSTRACT
Cannabinoids are derived from cannabis, which is taken, commonly, as a “recreational” drug. Although the pharmacological effects of cannabinoids are more likely to produce performance deterioration, rather than enhancement, cannabinoids are one of the more frequently detected classes of drugs during anti-doping tests conducted through World Anti-Doping Agency (WADA) laboratories. It has been suggested by some that cannabinoids should be removed from the WADA Prohibited List. The chapter explores these issues in detail. Cannabinoids produce both physical and psychological effects, the extent of which will vary depending on patterns of use. The adverse effects of cannabinoids on physical and psychological function means that cannabis consumption can be dangerous in sports that rely on clear thinking, quick reactions and split-second timing. Particular adverse effects include somnolence, dizziness, euphoria and feelings of paranoia. Anxiety and tachycardia may also occur. All these effects are incompatible with most athletic endeavours.
