Yours definitely sounds like it had the THC element in it, @Zoffiel !! Keep in mind tho - the stuff that was around back in the 60s/70s was NOWHERE NEAR as strong as what is around now - that 'high' element back then, was actually quite 'low' - and nowhere NEAR as addictive as today's modern stuff is! The 'current stuff' is also quite mind altering as well - with people going quite schizophrenic on it - and VERY addictive. The current stuff has been manipulated & genetically modified over the last few decades to give a much bigger high (in the drug sense) so your current 'hillbilly mix' would have been MUCH stronger than what you may have tried back in the old days - hence you not really liking the feeling!
My sister has some (I think it was attained legally thru prescription) and I tried it for one night when she was down at Easter - and it did nothing for me. (Similar to the one time I tried it back in the 70s!)
Personally I think it is criminal that Medicinal Cannabis Oil is not available 'easily' to those who need it.
@Mellyb - I hope that you will be able to access some (probably without the THC as it isn't needed for the pain/sleep control) & that it helps your Mum
