Effects of synthetic (JWH-018) cannabinoids treatment on spermatogenesis and sperm function

JWH-018 is a synthetic cannabinoid which has been increasingly used by adolescents and adults, and is known to cause severe multi-organ failure. However, little is known about the complications and toxicological effects of JWH-018 on reproduction system. Therefore, the aim of the present study is to investigate the effects of JWH-018 on testis and spermatogenesis. Thirty CD-1 male rats were distributed into six groups, control group (C1 and C2), ethanol group (E1 and E2), and JWH-018 group (JWH1 and JWH2), which were administered 0.9% NaCl, %100 ethanol, and JWH-018 (0.3 mg/kg) respectively for 9 d. We euthanized C1, E1, and JWH1 group mice at day 2 and C2, E2, and JWH2 group mice at 45 d after the last injection to evaluate the acute testis damage and potential recovery of spermatogenesis. The histopathology of seminiferous epithelium was evaluated and organ weight, sperm concentration and motility, membrane integrity, and serum testosterone levels were statistically analyzed. In JWH1, seminiferous tubule degeneration, partial germ cell depletion disorganized seminiferous epitheliums were seen. We also observed significantly decreased sperm concentration, sperm motility, intact membrane, and testosterone levels in JWH1 group compared to other groups. Forty-five days after the JWH-018 treatment, sperm concentration, motility, and testosterone level were increased, suggesting that testis and spermatogenesis can recover. We concluded that the use of JWH-018 may adversely affect male reproductive potential and testis histopathology.

Synthetic cannabinoid JWH-018 and psychosis: An explorative study

Background Aroma, Spice, K2 and Dream are examples of a class of new and increasingly popular recreational drugs. Ostensibly branded “herbal incense”, they have been intentionally adulterated with synthetic cannabinoids such as JWH-018 in order to confer on them cannabimimetic psychoactive properties while circumventing drug legislation. JWH-018 is a potent cannabinoid receptor agonist. Little is known about its pharmacology and toxicology in humans. This is the first research considering the effects of JWH-018 on a psychiatric population and exploring the relationship between JWH-018 and psychotic symptoms. Method This paper presents the results of semi-structured interviews regarding the use and effects of JWH-018 in 15 patients with serious mental illness in a New Zealand forensic and rehabilitative service. Results All 15 subjects were familiar with a locally available JWH-018 containing product called “Aroma” and 86% reported having used it. They credited the product's potent psychoactivity, legality, ready availability and non-detection in drug testing as reasons for its popularity, with most reporting it had replaced cannabis as their drug of choice. Most patients had assumed the product was “natural” and “safe”. Anxiety and psychotic symptoms were common after use, with 69% of users experiencing or exhibiting symptoms consistent with psychotic relapse after smoking JWH-018. Although psychological side effects were common, no one reported becoming physically unwell after using JWH-018. Three subjects described developing some tolerance to the product, but no one reported withdrawal symptoms. Conclusion It seems likely that JWH-018 can precipitate psychosis in vulnerable individuals. People with risk factors for psychosis should be counseled against using synthetic cannabinoids.
