Map: How much does marijuana cost in the U.S.?

But while marijuana for recreational use is still illegal in 48 states and the District of Columbia, that doesn’t mean there aren’t buyers and sellers. An interesting set of data, compiled by PriceOfWeed.com, shows high-quality marijuana is most expensive in North Dakota, and in several Mid-Atlantic states.

The Web site has been soliciting input from marijuana purchasers, anonymously, for several years. They ask where a purchaser lives, and how much they paid for the drug. Mapmaker Renzo Lucioni crunched the data and found the cost of high-quality marijuana is consistently lowest on the West Coast.
