The whole point of cannabis is THC.. which is why people in chronic pain take it. Cannabis Oil.. which is available at Holland and Barratt and any good "high street bong " retailer has the THC removed so is nothing more than branded Snake Oil.
Maybe people fall for the Placebo effect?
If Kruis is making money out of it then fair pay to him.. but I can't help feel its another Wray"fronted" business .. a bit like Wigglesworth and Barrett's coffee empire business.
