   MEDICAL OR RECREATIONAL MARIJUANA AND DRUGGED
                                  DRIVING

Paul J. Larkin, Jr.*

                                   ABSTRACT

   Beginning  in the 1920s and  lasting for seventy years, state and federal law
treated marijuana as a dangerous  drug and as contraband, forbidding its cultiva-
tion, distribution, possession, and use. Over  the  last two decades,  however;
numerous  states have enacted laws permitting marijuana  to be used for medical
treatment. Some also permit its recreational use. Those laws have raised a host of
novel legal and public policy issues. Most of the discussion, and almost all of the
litigation, has involved the respective roles of the states and federal government
and  how each one  may and  should deal with this very controversial subject. One
issue that has received  little attention in the legal community is the risk that
medical  and recreational marijuana laws will pose to highway  safety. Will those
laws increase, decrease, or leave untouched the rate of accidents and fatalities on
our nation's roadways? How   should the criminal justice system-in particular; its
law  enforcement officers-address  the problem of drugged  driving in general
and  in states with medical marijuana laws? This Article addresses those issues.
Some  of the possible solutions do not  involve changing  the law. Training law
enforcement  officers to better spot drugged drivers, developing  safe, reliable,
portable, and inoffensive devices to test drivers for marijuana use on a highway
shoulder, identifying a particular concentration of marijuana in the blood or some
other bodily fluid that can be used to establish impairment-those and other steps
can be  taken without changing the legal framework for addressing  the problems
that occur when people drive under the influence of an intoxicating substance. But
it also may be necessary to modify the laws governing alcohol in order to reduce
the crashes caused by marijuana  use. People often take those drugs in combina-
tion, and  a marijuana-alcohol  cocktail is more  debilitating than either drug
consumed   alone. States therefore may need to lower their thresholds for drunken
driving in order to dissuade people who use marijuana and alcohol together from
getting behind the wheel.
