Yes. Marijuana DUI cases in Providence are often more defensible than alcohol DUI cases because of the lack of a per se THC limit. Defense angles include challenging the officer's basis for the initial stop, contesting the field sobriety test administration (these tests were designed for alcohol impairment and have lower reliability for marijuana), questioning the Drug Recognition Expert's qualifications and methodology, attacking the chain of custody on blood or urine evidence, and arguing that THC presence does not prove current impairment. The lack of a bright-line legal limit creates real space for reasonable doubt at trial.
