I have been in servere pain since the age of 5. Critical Widow is the right strain for my illnesses from a car accident fibromyaliga, pinch nerve in my neck, heriated disk in my neck, torn rotor cup in my right shoulder, etc. When you first talke a puff you don't feel it, but then it creeps up. my pain was a 20 instead of 1-10 level of pain. Critical Widow, made me sleep, made my pain go down to an 8, It last about 6 hrs for me. I am so happy at last I am relieved of a lot of pain. Thank you Leafy. And all the workers that deliver.
