Background and Clinical Significance: The recreational use of semisynthetic cannabinoids (SSCs) is increasing, and SSCs account for more than 40% of all new substances reported at the European level. Although designed to mimic the effects of tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis, evidence suggests that certain SSCs may elicit stronger, prolonged and unintended pharmacological effects. SSCs are easily accessible, particularly via online retailers, but in some countries, SSCs are also sold in convenience stores or specialty stores selling legal low-THC or cannabidiol (CBD) products. Often, SSCs are sold as “legal highs” and are found in various forms, including herbal mixtures (spice), vape products, and edibles such as cookies and candies, specifically targeting young users, including children. The products are frequently mislabeled and sold as souvenirs or aromatic potpourri to bypass regulations. Case Presentation: We present a case of a male in his early forties who was admitted to the Emergency Department due to noticeable deficits in alertness and responsiveness after recreational ingestion of two cannabis cookies labeled to contain 40 mg “CC9” and a bite of a gummy with unknown contents. The patient experienced vomiting and visual problems, and suffered from nine days of cognitive and physical impairment. HHC-C9, a novel SSC, was detected in blood through forensic toxicological analysis. Conclusions: Recreational use of HHC-C9 can cause vomiting, visual disturbances, and drowsiness, potentially requiring hospital treatment. Potency, clinical effects, and toxicity of SSCs can vary significantly, and in combination with easy accessibility, SSCs pose a potential risk of intoxication to unaware consumers. Full article

In the context of people’s gradually rising consumption levels and the urgent need to upgrade the tourism market, the continuous homogenization of tourism souvenirs is beginning to seriously affect the shopping experience of tourism tourists. This study aims to explore how tourists perceive the phenomenon of the homogenization of tourism souvenirs and how this phenomenon affects tourists’ continuous purchase intention. This study constructs a hypothesis model of the relationship among perceived homogeneity, perceived value, and continuous purchase intention based on a perceived value perspective and validates the model using structural equations. These findings are as follows: (1) Tourists’ perceived product homogeneity and perceived service homogeneity have significant negative effects on perceived product value and continuous purchase intention. (2) Perceived service homogeneity has a significant negative effect on tourists’ perceived emotional value. (3) Perceived product value and perceived emotional value have significant positive effects on continuous purchase intention. The study also explores how to enhance tourists’ perceived value through innovative product design and service system construction. The findings can provide valuable insights for promoting the sustainable development of the tourism market and tourists’ continuous purchase intention. Full article
