I offer a cleaned version of the state-level NSDUH in Stata .dta and Excel .xlsx formats here.
The NSDUH is mostly quite good as government datasets go- they share individual-level data in many formats and with the option to get most years together in a single file. But due to privacy concerns, the individual-level data doesn’t tell you what state people live in, which means it can’t be used to study things like state policy. SAMHSA does offer a state-level version of their data, but it is messy and only available in SAS format. So I offer the 1999-2019 state-level NSDUH Small Area Estimation Dataset in Stata .dta and Excel .xlsx formats here.
If you have Stata I recommend using that version, since the variables are labelled, making it much easier to understand what they represent.
This is the latest addition to my data page, where you can find cleaned/improved versions of other government datasets.
