I have done a lot of research on CBD oil for pain and for stopping opiates, as well as experienced it for myself. I just watched a new documentary about how opiates rewire the brain to crave opiates and stop producing dopamine (makes you happy...) unless given opiates. It also breaks apart the structure that allows you to think clearly and damages thought processes.
The scientist were analyzing brains of deceased opiate users and the affect of CBD. The CBD repairs the brain and rewires it to not crave opiates so much and start producing some dopamine without opiates. Since I live in WA, I purchased a large amount of edible CBD oil and vape cartriges. They ranged from 90%CBD and 10%THC to 50/50. First I tried to cold turkey quit from a 35mg dose of Methadone (prescribed for pain by my Doc).
It was a nightmare. After 3 days of not being able to hold down any food or water and sweating, no sleep...I was afraid I could dehydrate and die. I had to taper off over a month period while taking larger and larger amounts of CBD/THC oil. I had tried this before with no success. This time it worked. Although it did require taking up to 6 containers a day with 100mg oil at 90/10 ratio and using the vape pen once an hour. It cost me about $65 a day, but that is a lot cheaper than an opiate habbit that is getting out of control or no longer effective enough for pain. I still take CBD, but in smaller amounts and have been off opiates for 4 months. Also had to exercise, epsom baths, sauna, drink water, eat healthier, yoga, massage...to get my body and brain back in shape and learn to cope with chronic pain in other ways such as CBD/THC oil, yoga, massage, inversion table, light cardio, ibuprofen occasionally, meditation...
Here are a few links showing studies of sucess rates of people reducing or quitting opiates with vs without CBD. 67% more success rate with CBD.
