Washington v. Fraser (Majority)
Annotate this CaseIn 2012, when Washington voters approved Initiative 502 legalizing recreational cannabis, it modified the driving under the influence (DUI) law and created a prong under which a person can be convicted of DUI depending on the level of tetrahydrocannabinol (THC) found in one’s blood. Douglas Fraser III was convicted of DUI under the per se THC prong of RCW 46.61.502(1)(b) for driving with a THC blood level of 9.4 +/- 2.5 ng/mL within two hours of driving. On appeal, Fraser challenged the constitutionality of this prong of the DUI statute, claiming that the statute was not a legitimate exercise of the legislature’s police power, that it was unconstitutionally vague, and that it was “facially unconstitutionally overbroad because no scientific evidence supports the conclusion that there is a per-se concentration of active THC at which all or most drivers would be impaired.” The Washington Supreme Court disagreed with all of Fraser’s contentions raised on appeal and affirmed his conviction.
