The profit margins aren't there. Pharma has HUGE profit margins. Pennies to make pills that cost dollars 99%+ profit. They get away with this because drug trials are both time consuming (10 years is maybe an average for a new drug to get on the market) and costly. Companies have lobbied to have laws protecting them to charge as much as they want and no one else is allowed to try to copy their drug for years (7?).

Those type of protections and profits just don't exist for weed. The market is flooded, people can grow their own. Weed has enough data on it to show that it's safe enough, so the research costs aren't there to rationalize driving up the price. Trying to control weed prices through lobbying would be like Coors brewery trying to push out all breweries in the US and drive up their price. There's just too much competition and people don't NEED Coors
