Hello, I have tried it for nerve pain and found it to be quite effective, not miraculous but effective and the stuff you buy over the counter has none of the "get high" components in it so no need to worry there. Here in NI there seems to be a company who have quite a lot stands in shopping centres The number of different products and delivery methods is mind blowing and I think how expensive it is varies on the method you choose. I got some in Holland and Barrett the first time but found it wasn't good enough quality (I think that's an important factor to look for and I found it out when I was doing some reading) and then I got some off the internet...there are a few quite big suppliers that have been in the press lately. I think there is another longer thread on here about CBD oil started about 3 weeks ago maybe?
