OROVILLE — A Chico marijuana advocate was sentenced to state prison after he rejected an offer of probation Wednesday.

The sentencing of Joel Kelly Castle on two pot charges in Butte County Superior Court had to be briefly postponed after Castle began yelling about the prosecution's statements about his out-of-court conduct.

Bailiffs escorted the 63-year-old man from the courtroom after Judge Robert Glusman ordered him to return later.

When the hearing resumed, Glusman admonished the defendant to refrain from interrupting if he wanted to participate. The judge confirmed that Castle was rejecting a proposal for three years of probation if it included prohibitions against the use of medicinal marijuana.

Glusman ultimately sentenced Castle to the lower term for the charges of possessing pot and selling the drug. The total term was two years, eight months in state prison although Castle has credit for serving 706 days, or about 70 percent of the sentence.

Castle's outburst came during the initial arguments about the prison term.
