Yes, materially. Marijuana DUI has no specific BAC equivalent - the state has to prove actual impairment through officer observations, field tests, and Drug Recognition Expert evaluations. There is no per se threshold like the 0.08 BAC for alcohol. THC stays in the body long after the impairing effect, making "presence vs impairment" a key defense angle.
