A man arrested for marijuana possession after he was pulled over for speeding entered not guilty pleas Thursday in Albany County District Court.

John Phillip Jacobs, 28, pleaded not guilty to one count of possession of a controlled substance and one count of possession with intent to deliver. If convicted on both counts, he could face up to 15 years in prison and $20,000 in fines.

Court documents say on March 22, an Albany County Sheriff's deputy stopped a gray Mazda with California plates for speeding. The deputy reportedly clocked the rented Mazda at 90 mph.

According to the deputy's affidavit, Jacobs couldn't find his rental agreement for the vehicle and said it might be in the trunk. The deputy accompanied Jacobs to the rear of the vehicle and, when Jacobs opened the trunk, the deputy reportedly smelled a strong odor of marijuana coming from the trunk.

The deputy allegedly found a paper bag in the trunk and asked Jacobs what it contained. According to court documents, Jacobs first said he didn't know but later said there was marijuana in the bag.

A search of the vehicle allegedly turned up two plastic bags containing marijuana weighing a combined 272 grams as well as one clear plastic container containing about 19 grams of marijuana.

In total, the deputy allegedly found 291 grams of pot -- about half a pound -- and one pipe in the car. The affidavit says Jacobs told the deputy he was visiting a friend in California who had a pot farm, and the friend asked Jacobs to deliver marijuana to the friend's twin brother in Colorado.

According to the affidavit, Jacobs said he was willing to deliver the marijuana.

During a police interview, a passenger in the vehicle reportedly named the person who allegedly gave Jacobs the marijuana. Court documents say the passenger told police the pipe and clear plastic container of marijuana belonged to Jacobs.

Judge Jeffrey Donnell scheduled Jacobs' trial for Sept. 7-8. Jacobs remains free on $5,000 signature bond.
