I have had mixed reactions on two different occasions when I smoked Marijuana.
The first time I took it for pain my pain increased tremendously and it did not help. The second time I tried from a different supplier and I had good pain relief. I could hardly move my neck with it being so stiff and painful, after having some weed my neck loosened up and I started flexing it in all directions. I even heard some cracking sounds while moving it around.
I think the reason for it not working and then working is because I had purchased two different strains of Stavia
