This piece of research supports the experiential,qualitative work I have undertaking.This has involved spending a lot of time in Amsterdam and,as you can imagine,has been hell!
This supports what I have done.In order to reduce the effect of tolerance to opiates,ie you have to keep increasing the dose to get the same effect,supplement them with medical-prescribed and legal-cannabis=Nabilone tablets better as Sativex is off limits unless you are rich.Some say the whole plant is best.
