I live in the uk and suffer from manic depression episodes, I’ve tried medication, none have helped. I’ve been looking into weed and would like to know the safest method for using?

One of my disorders is Manic Depression also called Bipolar Disorder my opinion is they don't know enough about Marijuana to prescribe it for Bipolar Disorder also i wouldn't just want to smoke that stuff. Now if it came in pill form and was FDA for Bipolar Disorder i might take the pill form or the medical form but just to smoke it no way i would not do it. I believe there's lot more studying needs done plus i would want it to cause me to become hooked on it . I know people are using it for their children who has Seizure disorders that have crippled them most of their life but than again people are taking chances giving that to their children you got to be careful that stuff can be addictive so that's what makes me keep searching for more and better Bipolar Disorder medications.
