From a medical standpoint, cannabis contains compounds like THC and CBD that have shown promise in treating certain conditions such as chronic pain, epilepsy, and nausea from chemotherapy. However, the scientific evidence is still emerging, and the full therapeutic potential and risks are not yet fully understood. Medical cannabis requires more rigorous clinical trials to clarify effective dosages, long-term impacts, and interactions with other drugs. This cautious approach helps explain why the NHS remains hesitant to widely prescribe cannabis despite its legal status.
