An analysis of the relationship between alcohol and marijuana use trends with fatal accidents for states with different levels of marijuana legality. States with more liberal marijuana policies experienced higher rates of drug-related automobile fatalities than states with only illegal or medicinal marijuana.

I predicted only states with illegal and decriminalized marijuana would experience comparatively lower rates of crashes involving alcohol.

Update: There are major problems with the significance testing towards the bottom of this page and FARS data. This project is here because I like some of the data visualization aspects.

Alcohol and marijuana use trends inspired further investigation into their relationship with automobile accident involvement rates.
