Medicinal use of cannabis in cancer patients in San Carlos de Bariloche: a survey-based study

Abstract

INTRODUCTION: The medicinal use of cannabis in cancer patients has become popular in recent years. In order to provide advice that results in a more effective and safe use, it is necessary to know the experience and expectations of users. The objective was to know the reasons and experience of the medicinal use of cannabis in adults with oncological diseases in San Carlos de Bariloche (Río Negro province). METHODS: The study was based on a self-administered online survey on cannabis use, time and reason for use, degree of satisfaction, professional advice, route of administration and adverse effects. RESULTS: A total of 201 patients participated, of which 19% used cannabis and 31% had previously used it. The main form of use was oil. The main reasons for use were to treat pain, sleep better and feel better. The experiences were satisfactory or very satisfactory for more than 50%, and the most favorable ones were to treat pain, improve mood, tolerate chemotherapy, and sleep better. Lack of usefulness, adverse effects, doubts about the dose, time of use and quality of the product purchased were mentioned among the reasons for the decision to stop using it. Less than 50% of the patients had received professional advice on the use of cannabis. DISCUSSION: Half of the participants used cannabis. This survey provides a useful diagnosis to foster policies that reflect the needs regarding the use of cannabis.
