Replication package for "Comparative Effects of Recreational and Medical Marijuana Laws On Drug Use Among Adults and Adolescents"

Alex Hollingsworth, Coady Wing, and Ashley Bradford Journal of Law and Economics

You can cite this replication package using zenodo, where an archival version of this repository is stored.

Overview

The code and data in this replication package will replicate all tables and figures from raw data using Stata, R, and a few unix shell commands.

The entire project can be replicated by opening the stata project file rec-mj.stpr and then by running the code/00-run-file.do do file. This file will also run the necessary R code. The paper can be rebuilt using the latex file manuscript.tex.

Using a 2019 MacBook Pro with a 2.3 GHz 8-Core Intel Core i9 processor and 32 GB of RAM, the entire replication takes a little more than 4 hours. The majority of this time is spent on two randomization inference procedures. In code/00-run-file.do, the user can choose to not run the randomization inference code by altering line 107 to be global slow_code 0. If this is done the entire replication will take less than 15 minutes.

Note: The github version of this replication package only contains the code and output. The zenodo version of this replication package contains all raw data and data used in analysis (as well as the code).

Legalization and dispensary opening dates

See file raw_data/marijuana_laws/state-marijuana-laws-12-11-20.xlsx for key legalization and dispensary opening dates.
A zipped folder with source pdfs for each of these dates can be found in raw_data/marijuana_laws/SourcePDFs.zip

Software Requirements

Stata (code was last run with version 15.1)
- the program code/00-run-file.do will install all stata dependencies locally if line 61 is set to local install_stata_packages 1
- All user-written stata programs used in this project can be found in stata_packages directory

R 4.1

We use the package renv for this project
- The renv.lock file has the version of each R package used in this project.

Portions of the code use shell commands, which may require Unix (the analysis was done on a mac).

Instructions to Replicators

Edit line 43 of code/00-run-file.do to R executible path
- e.g., global r_path "/usr/local/bin/R"
Edit line 61 of code/00-run-file.do if you'd like to install stata code again rather than running code using stata_packages folder
Edit line 103 of code/00-run-file.do if you want to build analytic data from raw data
Edit line 107 of code/00-run-file.do if you want to run slow code (randomization inference)
Compile latex/manuscript.tex to recreate paper.

The provided code reproduces all tables, figures, and results in the paper.
