Voters in California, Maine, Massachusetts, and Nevada approved recreational marijuana measures on Tuesday night, marking an historic moment in the movement to legalize the drug nationwide. With these four states joining the ranks of Alaska, Colorado, Oregon, Washington, and Washington D.C. — which all backed similar pot initiatives in recent years — legal weed is now a reality in states home to about 20 percent of the country’s population.

But law-abiding bud connoisseurs beware: each state has developed its own intricate set of rules that govern recreational marijuana, which can be a little confounding for the uninitiated. In Maine, for instance, an adult can purchase and possess up to 2.5 ounces of cannabis flower — more than double the 1 ounce people in California will be permitted to carry on their person. Want to grow your own weed in Boston? Great, Massachusetts will soon let adults cultivate up six plants inside their homes. As for Nevada? The new initiative there will not allow someone to grow marijuana within a 25-mile radius of the nearest dispensary.

And let’s not even start with varying amounts of edibles and concentrates that are allowed on the books in different places. That will just harsh your mellow.

To alleviate the stress and confusion, Vocativ has provided a (legal) pot smoker’s companion for each state where recreational marijuana is now legal. Happy trails.

And, for anyone who forgot: here’s a recap of what it looks like in the states where recreational marijuana has been legal for a while.
