The marijuana pizza must be ordered special but, as Anthony Risling of Mega iLL told the CBC News , the ingredients are all ready to go as soon as a customer makes the order and shows their medical marijuana licence."Basically we infuse it through an oil extraction process, where we drizzle the oil onto the pizza and it medicates you when you eat it," Risling said. "It's a little different effect from smoking it. It takes maybe about a half hour for it to activate."The pizzeria, at Kingsway and Fraser, charges an extra 10 bucks to turn a regular pizza into something of a higher quality. They believe they are the only restaurant in Canada that serves marijuana pizza. The country's medical marijuana system is undergoing changes so it's unsure if the pizzeria will be able to offer the marijuana pizza for much longer.
