Here are a couple important cases regarding DWI drug charges in New Jersey:
State v. Bealor, 187 N.J. 574 (2006)
The NJ Supreme Court held that competent lay observations of the fact of intoxication, coupled with additional independent proofs tending to demonstrate defendant’s consumption of narcotic, hallucinogenic or habit-producing drugs as of the time of the defendant’s arrest, constitute sufficient proofs to establish DWI beyond a reasonable doubt.
State v. DiCarlo, 67 N.J. 321 (1975)
The NJ Supreme Court held that the definition of narcotic drug in the Controlled Dangerous Substance Act is not of controlling weight in interpreting the same phrase appearing in N.J.S.A. 39:4-50.
