6. Legal marijuana would cause carnage on the highways

Although marijuana, when used to intoxication,
does impair performance in a manner similar to alcohol,
actual studies of the effect of marijuana on the automobile
accident rate suggest that it poses LESS of a hazard than
alcohol. When a random sample of fatal accident victims
was studied, it was initially found that marijuana was
passociated with RELATIVELY as many accidents as alcohol.
In other words, the number of accident victims intoxicated on
marijuana relative to the number of marijuana users in society
gave a ratio similar to that for accident victims
intoxicated on alcohol relative to the total number of alcohol
users. However, a closer examination of the victims revealed
that around 85% of the people intoxicated on marijuana WERE
ALSO INTOXICATED ON ALCOHOL. For people only intoxicated on
marijuana, the rate was much lower than for alcohol alone.
This finding has been supported by other research using
completely different methods. For example, an economic analysis
of the effects of decriminalization on marijuana usage found
that states that had reduced penalties for marijuana
possession experienced a rise in marijuana use and a decline in
alcohol use with the result that fatal highway accidents decreased.
This would suggest that, far from causing "carnage",
legal marijuana might actually save lives.
