Looking For Mental Health And Addiction Data Set

Need help finding a data set

I’m working on a multiple regression model and I’m having so many problems with finding a data set that has interval variables.

Currently, I’m looking at (broadly) addiction/drug usage and mental health. I was using the NSDUH data set, but it is massive and a tutor told me that the variables aren’t useful for what I’m doing (bc it’s lack of scalable ones which results in too many dummy variables).

This is just for a class and I need to create a straight forward model for my final paper, but it seems so difficult. Does anyone have any recommendations? I just want to be done with it.
