Background: The United States has seen a rapid increase in the use of Δ-8-tetrahydrocannabinol (Δ-THC), a psychoactive compound similar to Δ-9-tetrahydrocannabinol (Δ-THC). This study aimed to explore themes in Δ-THC related tweets from U.S. jurisdictions with varying cannabis regulations from 2020 to 2022.
Methods: Tweets mentioning Δ-THC were collected using search terms: D8, Delta-8, and Delta8 THC. The tweets were date-restricted from January 21, 2020, to May 31, 2022, resulting in 139,843 tweets. The final dataset included 61,800 U.S. tweets with complete location data. A subset of 1,000 tweets ( = 250 for each legal jurisdiction) was selected for content analysis.
Results: Three main themes related to Δ-THC emerged across all jurisdictions: 'Sales and Advertising', 'Policy', and 'Personal Use'. In states where cannabis was legal for adult use, sales-themed tweets were most prevalent, promoting product sales and discounts. 'Policy' tweets were more common in medical CBD-only (34.5%) and fully illegal (24.8%) jurisdictions than in those with legalized medical (20.4%) and adult use (20.2%). Tweets about personal use appeared at similar rates in fully illegal (27.7%), medical (25.0%), medical CBD-only (24.5%), and fully legal jurisdictions (22.8%). Reports of adverse effects were frequent in tweets from fully illegal (28.9%), fully legal (27.7%), and medical (27.7%) jurisdictions, with the lowest frequency in medicinal CBD-only (15.6%) jurisdictions.
Conclusion: The current study on the public discourse on Twitter indicates that discussions about the use and marketing of Δ-THC are present in all U.S. jurisdictions, not just those without legal recreational cannabis markets.

Introduction: Phencyclidine, a dissociative anesthetic with hallucinogenic effects, is commonly abused as a recreational drug. Phencyclidine analogs are compounds produced by substitutions of the phenyl and piperidine rings of phencyclidine. Illegal use of phencyclidine and its analogs has symptoms such as addiction, confusion, and increased tendencies toward violence.

Recent advances in artificial intelligence (AI) and machine learning (ML) applications have elevated accomplishments in various scientific fields, primarily those that benefit the economy and society. Contemporary threats, such as armed conflicts, natural and man-made disasters, and illegal immigration, often require fast and innovative but reliable identification aids, in which forensic anthropology has a significant role. However, forensic anthropology has not yet exploited new scientific advances but instead relies on traditionally used methods.

Background: Opioid substitution therapy (also known as 'opioid agonist therapy' or 'medication treatment of opioid use disorder') is associated with improved health and social outcomes for people who use heroin and other illicit opioids. It is typically managed in the community and is not always continued when people are admitted to hospital. This causes opioid withdrawal, patient-directed discharge, and increased costs.
