A Worcester man freely admitted to police he was smoking marijuana and was high while driving on Tuesday but argued that being stoned and behind the wheel is perfectly legal.Officers disagreed, arresting Keith Jackson, 25, after they pulled him over on Union Avenue at 4:35 p.m., according to a police report filed in Framingham District Court on Wednesday.Several officers were on a detail on Union Avenue when a passing Toyota sedan drew their attention, the MetroWest Daily News reported."We all simultaneously recognized and commented to each other about an extremely strong odor of burnt marijuana coming from the motor vehicle as it passed by us," police wrote in the report.An officer followed the car, and the smell got stronger. He pulled the car over and spoke to Jackson, who didn't deny smoking marijuana and handed the officer a marijuana joint.Police wrote, "He said, 'Yes,  I always do it (drive while smoking marijuana). It relaxes me. It's not against the law to smoke and drive. I always do this. I smoke the joint all the way back to Worcester.'"The officer told Jackson it is illegal to drive under the influence of marijuana, and Jackson argued with him and asked to speak to a superior officer to "straighten" everything out."Jackson was happy and laughing during the entire interaction," police wrote.However, Jackson became angry when officers arrested him. During booking, a commanding officer asked Jackson about his red eyes. Jackson said they were red, "because I'm high," according to the report.Police charged Jackson, of 17 Florence St., Worcester, with driving under the influence of drugs and driving to endanger. Police also cited him for possession of less than an ounce of marijuana, because Jackson had given them a small bag of marijuana.At Jackson's arraignment on Wednesday, Framingham District Court Judge Lynn Coffin Brendemuehl released him without bail. He is due back in court on June 14 for a pretrial conference.
