This course page is a blog-style discussion of ketamine therapy and cannabis use, based on the author’s personal experience. It explores how ketamine may help relieve treatment-resistant depression while also describing the author’s view that cannabis did not remain a helpful companion treatment over time. The content addresses mental health management, self-medication, anxiety, depression, and the process of recognizing underlying behavioral and emotional patterns. It also reflects on the limits of ketamine as a treatment when broader recovery work is needed. This material is most relevant for people interested in ketamine therapy, depression recovery, and the interaction between ketamine and cannabis. It is presented as a narrative and reflective article rather than a formal training course.
