Summary
Public sentiment towards psychedelics like psilocybin and LSD is surprisingly neutral to slightly positive, contrasting sharply with highly negative views on substances like heroin. Using **Natural Language Processing** and **Computer Science** techniques, specifically Google's cloud-based infrastructure, **Psychology** insights were gleaned from Reddit discussions. This approach effectively captured public perception in **Psychedelics and Drug Studies**, suggesting growing acceptance of therapeutic potential. **Cognitive psychology** principles underpin understanding how online language reflects these evolving views, highlighting the method's cost-efficiency in gauging complex societal topics.
Abstract
New methods that capture the public's perception of controversial topics may be valuable. This study investigates public sentiments toward psychedelics and other substances through analyzes of Reddit discussions, using Google's cloud-based Natural Language Processing (NLP) infrastructure. Our findings indicate that illicit substances such as heroin and methamphetamine are associated with highly negative general sentiments, whereas psychedelics like Psilocybin, LSD, and Ayahuasca generally evoke neutral to slightly positive sentiments. This study underscores the effectiveness and cost efficiency of NLP and machine learning models in understanding the public's perception of sensitive topics. The findings indicate that online public sentiment toward psychedelics may be growing in acceptance of their therapeutic potential. However, limitations include potential selection bias from the Reddit sample and challenges in accurately interpreting nuanced language using NLP. Future research should aim to diversify data sources and enhance NLP models to capture the full spectrum of public sentiment toward psychedelics. Our findings support the importance of ongoing research and public education to inform policy decisions and therapeutic applications of psychedelics.
