This paper proposes a theoretical framework suggesting that mental state, stress levels, and emotional well-being may significantly influence disease progression and recovery through indirect physiological mechanisms. Particular attention is given to the interaction between psychological stress, metabolic indicators (such as urine odor changes), and immune system performance. Furthermore, the paper explores the hypothesis that cannabis oil may contribute to improved outcomes not through direct cytotoxic effects on cancer cells, but by enhancing psychological well-being, social interaction, and overall physiological balance, thereby supporting the body’s natural defense mechanisms.
