"Weedepreneurs" are those taking advantage of the growing marijuana business. This is evidenced in Colorado in the US but the business is quickly expanding to Canada where legalized recreational marijuana sales in Canada are expected to eclipse those of alcohol. This new business should be regulated so that prices are fair, and it's only a matter of time before this happens.
I think as long as they marijuana is taxed, the government will get their fair share and help to regulate prices. Since it is such a new market, there is still a lot of gray area as far as government involvement and regulation are involved. In due time, I think it will all be running smoothly.
Yes, prices for weed will be able to be regulated fairly, since we can regulate prices of most products fairly. If we walk into a grocery store, the prices of most products are around the price we would expect. The same will go for weed, since competitors will rise up.
With sales that high, there is no reason that prices should go up. They should either stay steady or fall, given that there is already plenty of profit. Prices going up will only hurt the sellers, and cost them their businesses. There are plenty of other people that can get into the industry and offer it for a prices people are willing to pay.
