Police find driver sleeping/passed out in his car behind a closed business in the early morning hours. Driver admits to being “too fucked up to drive.” Search of car discloses evidence of recent marijuana use. Despite government claim that client was driving under the influence of drugs, no percipient witness exists to support claim of impairment by marijuana, which is beyond the understanding of lay persons, and requires expert testimony from the prosecution. Other admissions and statements of defendant are excluded by Defense Motion to Suppress. Standard field sobriety tests were mostly passed and are applicable only as to alcohol impairment. Massachusetts OUI Drugs Charge Dismissed for lack of prosecution.
