i've been experimenting with this stuff for a month, as i would with any new drug. by itself. it works well for nerve pain but not for chronic back pain. vaping it is fast acting but mild. sublingual works much better, even when using the vaping product. topical is great but only lasts 20 minutes. here's something controversial. people who know tell me that one must use full spectrum to get pain relief. i bot some crystal to try, but never got around to making juice n it was not full spectrum. i put 1/32 teaspoon under my tongue. the coarse crystals took time to dissolve, but it hit like a freight train. this might be dose related. i have no idea how much juice that would have made, so i can't compare. years ago, i picked up some kratom to try for pain relief. worthless for that, but i kept it around for fun. however, when used with cdb, the pain relief is amazing, even for chronic back pain. these things potentiate each other. i cut narcotics by 60%. unfortunately, this stuff doesn't get you high, but i get amazing vivid technicolor dreams. i enjoy that but not everyone does. CONCLUSION i highly recommend cdb for pain relief, especially when used in conjunction with kratom. however, most people might be better off with prescriptions. this is running me $50/week. in my special circumstances, it's worth it. i just ordered a couple of keys of kratom to go with it, n i'll be using both daily. but. $2600/year is kinda pricey. that's my report. .
