Also sidenote in Canada now, you can get really good weed for 15,000-20,000 baht/pound (~35 baht/gram) on the black market (in stores it's cheap too now, not just black market). This is the stuff they are selling for 300-600/gram in Thailand.
The premium AAAA weed in Canada is about 35,000-40,000 baht per pound. (~80 baht/gram). This is the stuff they are trying to sell for 600-800/gram here.
