My goodness ukcannabis you've provided some research searching for me this morning.Thank you.
Intrigueing, but the same confusion and uncertainty reigneth judging by the comments on a Sativex website.
I think doctors in some American states can prescribe federally banned cannabis medication without fear, because their home state regulators have a relaxed attitude as long as they pay the taxes.
It's a can of worms alright!
