Sativex is an even ratio of CBD and THC but its so damned low that it makes no bloody difference.This is from GW Pharma's PDF:
"Each 100 microlitre spray contains 2.7 mg delta-9-tetrahydrocannabinol and 2.5 mg Cannabidiol"
I have never heard of Sativex working for anyone who uses flower that was prescribed it.
I am one person that Sativex has worked for, who also uses flower.
I was prescribed Sativex for 5 weeks, and it was responsible for taking me out of a severe flare-up with my auto-immune disease, better for me, than Methotrexate/Prednisone combo. I was taking upwards of 10 sprays a day at the height of things.
It was my first experience using any cannabis product with 1:1 THC:CBD ratio, and it opened my eyes to the potential power of CBD.
I only stopped using Sativex after 5 weeks, as it wasn't covered by my insurer and I had to pay out of pocket...$$$. I started sourcing CBD-rich strains after this (this was in 2011)...and had to grow out a bunch of strains to find CBD-rich phenos.
Havent looked back since...and havent had a major flare-up since...
