Harry Monk:
I tried it for 2-3 months, mainly for arthritis, but I would honestly say that it didn’t make any difference at all, and neither did it make any difference to my mood (which is generally fairly calm anyway). I think that using a cannabis-based product which has had the THC removed is a bit like trying to wake yourself up a bit with a cup of decaffeinated coffee.
Dunno about vapes etc, but nice turn of phrase.
