Medical cannabis refers to the use of the cannabis plant and its compounds, particularly cannabinoids, for therapeutic purposes. It is prescribed by healthcare professionals to help manage various medical conditions, including chronic pain, epilepsy, and nausea associated with chemotherapy. The active compounds in cannabis, such as THC and CBD, interact with the body's endocannabinoid system to produce beneficial effects. In many regions, medical cannabis is regulated and can be obtained through licensed dispensaries. Patients typically need a prescription or recommendation from a qualified doctor to access these products legally. Research continues to explore its efficacy and safety for different health issues.
