An Iowa City man faces numerous charges Tuesday after police allegedly found more than 400 grams of marijuana in his car.

Altan “Big O” Thomas Jackson, 25, 1313 Marcy St., was charged June 14 with a drug tax-stamp violation, possession of a controlled substance, and operating while intoxicated.

Iowa City police said they stopped Jackson for failing to stop at a stop sign. When he appeared to be nervous, a K-9 was called over to the vehicle, according to the police report.

Officers said a search of the vehicle yielded 445 grams of marijuana.

Jackson allegedly told officers that the marijuana was “mostly for his personal use” and that he smoked a lot every day.

He also allegedly admitted that he was currently high and had smoked shortly before driving, police reports state.

Complaints said Jackson consented to a Drug Recognition Expert Evaluation and was allegedly determined to be impaired by the marijuana.
