Basic readings concerning drugged driving realities and laws

In addition to having a notable guest speaking in my marijuana law school seminar this week (basics here), we are starting a series of weeks in which students are to present to the class some readings and engage in discussion concerning the research topic that they are working up. This week, one of the topics to be covered is drugged driving, and here are links to the student-assembled reading:

Drug Impaired Driving: Understanding the Problem and Ways to Reduce It

Drug Per Se Laws: A Review of Their Use in States

(My students only need to read the Ohio section in the “Drug Per Se Laws” comparative article, though they (and other readers) might want to review the whole document for a national perspective.)
