CANNABIS: USO TERAPÊUTICO E DESAFIOS PARA SUA APLICABILIDADE MEDICINAL NO BRASIL

Introduction: The legalization of medicinal marijuana use has been a controversial and constantly debated topic in recent years worldwide. Marijuana, also known as cannabis, is a plant that contains various chemical components, including THC (tetrahydrocannabinol) and CBD (cannabidiol), which are the main compounds responsible for its medicinal effects. Although many countries have already established regulations for the therapeutic use of cannabis, there are still many barriers to overcome. Objective: To explore the methodology of therapeutic use and the challenges for the application of cannabis, focusing on its medicinal use, identifying notable challenges and the regulatory aspects involved. Methodology: This study is based on a bibliographic review with a qualitative methodology, centered on the subjective nature of the verified bibliography through literary studies. The works reviewed were published between 2020 and 2023, collected from three main sources: LILACS and PUBMED databases. Results: The review identified significant evidence pointing to the therapeutic potential of Cannabis sativa L., particularly in the treatment of neurological conditions such as epilepsy, multiple sclerosis, and anxiety disorders. However, it also highlighted the major regulatory challenges faced in countries like Brazil, where the cultivation of cannabis for medicinal purposes remains prohibited. This prohibition increases treatment costs and limits accessibility for patients. Additionally, the results revealed a growing acceptance among healthcare professionals and patients, suggesting a likely increase in the demand for medicinal cannabis in the coming years. Conclusion: Although there is robust evidence supporting the efficacy of cannabis for medicinal purposes, significant regulatory and legal barriers remain, particularly in countries with restrictive policies. A reformulation of regulatory frameworks is urgently needed to expand patient access and promote the development of local medicinal cannabis industries. Further investment in scientific research is also essential to ensure that regulatory decisions are based on comprehensive and context-specific data.
