@11 - "Instead, we are only just now talking about it, after the introduction of I-502"?
That's simply not true.
A per se DUI threshold for THC was introduced in the Washington State Legislature in January 2011 as HB 1648 -- five months before I-502 was filed. Colorado's first per se THC DUI bill was introduced in February 2011.
Fourteen other states have marijuana per se DUI statutes, the earliest of which was passed in 1983, the most recent of which was passed in 2007. Eleven of those statutes are zero tolerance, and half of those include inactive metabolites in addition to the active THC to which I-502 is limited.
The National Drug Control Strategy released in July 2011 by the Office of National Drug Control Policy identifies "encouraging states to adopt per se drug impairment laws" one of its top policy priorities.
This issue was not raised by I-502, and it is not going away for the foreseeable future.
@15, @18, @24 -- the science is in the "DUI Factsheet" that continues to be available here: http://www.newapproachwa.org/content/faq
. If you examine the graph on Page 2, you'll see that the available science indicates that risk of accident does, in fact, go down in correspondence to active THC levels between 0 and 5 ng/mL in whole blood (this is the initial dip in the line). However, at 5 ng/mL, the risk surpasses that of sober drivers.
New Approach Washington wants to end marijuana prohibition. We want Washington voters to take a decisive step in that direction in 2012. To accomplish that goal, we know we must deal with the political landscape as it exists now. The 5 ng/mL active THC DUI threshold in I-502 is reasonable and supported by the available science. Moreover, I-502 dedicates funding for additional research on this issue.
