Medical Marijuana For Pain?

 Hi All, I just want to ask if anyone ever tried using medical cannabis as an alternative meds? I have read many articles about medical marijuana and how it can help you in terms of chronic pain, glaucoma, eating disorder/anorexia, anxiety disorders and panic attacks, inflammation, even cancer and a lot more. Like this article about a marijuana strain called Kushberry from:http://www.ilovegrowingmarijuana.com/kushberry/ . Cbd and thc are also new to me and I don't even smoke. If this is true I cant find any solid conclusive evidence that speaks to its efficacy. Any personal experience or testimonial would be highly appreciated. Thanks
