It truly depends on the person. What works for one person may not be as effective for the next. From what I have heard Indica cannabis strains that are higher in THC provide the most pain relief. The higher THC levels, however, could send you into space, this is where many people are finding relief from strains that are actually higher in CBD, a nonintoxicating cannabinoid that helps tremendously with pain especially pain related to inflammation. This is what I've heard at least! Hope this helps!
