We are constantly voting in primaries and general elections. We vote in federal elections every two years, state elections generally at least as frequently, though often not in federal election year. We vote for mayor and city council and insurance commissioner and Secretary of State and county commission.
We don't need a referendum, we just need to choose representation that wants the same things we want. (Alternate formation: Americans do not want these things as much as some of us think they do.)
By referendum I meant to be able to vote directly on a specific law.
If you look at how weed was legalized, it required a referendum in many (most?) states because no representative wants to be the guy that has his face plastered everywhere when some kid dies after he smokes some legal weed and smashes into a pole, even if most his constituents wanted the policy.
Representatives generally have to be risk averse to get to the point they can even represent people on issues. This means they are extremely reluctant to vote for anything that might come back to bite them somehow, even if it is popular.

There is extremely overwhelming evidence that a supermajority of americans have wanted medical marijuana to be federally legal for many years. And overwhelming evidence the representatives have not been successfully bringing that forward.
