Spatiotemporal Mapping of Online Interest in Cannabis and Popular Psychedelics before and during the COVID-19 Pandemic in Poland

International Journal of Environmental Research and Public Health May 29, 2022 Ahmed Al-Imam, Marek A Motyka, Zuzanna Witulska et al. 7 citations

Psychedelics induce altered consciousness via the 5-HT2A receptor. Online searches in Poland for twenty psychedelics from 2017 to 2022 were analyzed using Google Trends data. Holt–Winters exponential smoothing revealed that twelve (60%) of the substances had significant seasonal patterns: psilocybin and ayahuasca showed annual seasonality, four substances (LSD, AL-LAD, DXM, DOB) had half-yearly seasonality, and six (cannabis, dronabinol, ergine, NBOMe, phencyclidine, salvinorin A) followed a quarterly pattern. The pandemic led to a significant positive change in search trends for psilocybin, ergine, and DXM. These spatiotemporal patterns may aid health authorities in monitoring and preventing addictions.

Pharmaceuticals (Basel, Switzerland) June 2, 2023 Ahmed Al-Imam, Marek A Motyka, Beata Hoffmann et al. 6 citations

Online searches for DMT, 5-MeO-DMT, and the Colorado River toad increased significantly from 2012 to 2022, with the strongest upward trend for 5-MeO-DMT. Geographic interest in DMT was highest in Eastern Europe, the Middle East, and Far East Asia; 5-MeO-DMT searches prevailed in Western Europe, Indo-China, and Australasia; and toad-related searches originated from the Americas, Australia, India, the Philippines, and Europe. The literature review covers DMT's shamanic history, present-day illicit use, and experimental trials for neurotic disorders, suggesting potential medical uses if legal status changes.

Opinion Mining of Erowid's Experience Reports on LSD and Psilocybin-Containing Mushrooms.

Drug safety May 1, 2025 Ahmed Al-Imam, Riccardo Lora, Marek A Motyka et al. 1 citation

Natural language processing of 2188 user reports from the Erowid forum reveals distinct emotional and thematic patterns in experiences with psilocybin mushrooms versus LSD. The BERT model classified most experiences as negative, especially for psilocybin mushrooms, while VADER indicated more positive experiences for mushroom users. RoBERTa, which achieved the highest accuracy, predominantly classified experiences as negative or neutral. Lexicon analysis showed psilocybin reports emphasize introspection and time dilation, whereas LSD reports highlight memory issues and cognitive disorientation. These analyses can inform harm reduction and policy-making.
