I won't go into the data about drug use and drug abuse, but we also used a structured and validated interview and we also asked them about previous and present use of antidepressants, basically SSRls and Monoamino-oxidase inhibitors, and we also asked them wether thay had taken these drugs with ayahuasca and if so, if they had an experience, and if so if they would describe the experience to us and they didn't have much space for that, it was very short, but it gives us an idea of what was happening
