I lived in an area where a farmer grew hemp for the oil. I may be wrong on this figure, but the word I got from an RCMP officer is that if the THC content of the hemp was greater than a percent, the whole crop was destroyed--by burning. I wrote a tongue-in-cheek SOP for the fire department there. I don't remember it all.

Gist of it was that the only firefighter wearing BA (breathing apparatus) would be the one who was going back and forth to the store to get snacks and the fire would be fought from downwind.

The chief gave me a look. I withdrew the proposed SOP (standard operating procedure).
