Measuring the price of marijuana relative to beer might seem a bit arbitrary. After all, marijuana, however cheap, is still illegal in most of the country. But there’s actually good reason to believe the comparison is not only telling, but a potentially significant indicator of future marijuana use in the U.S., especially among America’s poor and young.

For those in Oklahoma, for instance, a joint is quite the bargain. Marijuana costs only $2.09 per joint in the state (the least expensive of anywhere in the U.S.), while a Bud Light sells for roughly $0.87 a 12 ounce bottle —meaning that price of a joint is the same as the price of 2.4 beers. In Kentucky, where a joint costs about $2.61, and a Bud Light costs roughly $0.90, the ratio is closer to 2.9; in Arkansas, where a joint costs $2.58 and a Bud Light $0.86, it’s 2.99; and in Washington, where weed is $2.72 per joint and Bud Light $0.90 per bottle, it’s 3.01.

For those in Nevada, however, marijuana isn’t nearly as wallet-friendly. Marijuana costs more than $5.20 per joint in the state (the most in the country), while a beer runs for about $0.85—meaning a joint costs the same as more than six beers. In Wyoming, where a joint costs about $5.00 and a Bud Light costs just over $0.83, the ratio is roughly 5.99; In South Dakota, where a joint costs $5.02 and a Bud Light costs $0.86, it’s 5.86; and in Vermont, where weed is $4.51 per joint and Bud Light $0.86 per bottle, it’s 5.28.
