A former Warren County teacher awaiting trial for taking drugs to school faces new charges for allegedly taking drugs into Warren County jail.

Matthew R. Kiser, 44, of Warren, was charged Tuesday, Dec. 5, with contraband, possession of a controlled substance, adulteration or misbranding of a controlled substance, and tampering with evidence, after he was taken to Warren County jail on other drug charges.

According to the affidavit of probable cause, the arresting officer asked Kiser if he had anything illegal on him as they were leaving the district justice’s office and heading to Warren County jail.

Kiser “advised that he didn’t have anything illegal,” according to the affidavit.

“While the defendant was being booked in the jail, staff observed the defendant take an item out of his sock and put it in his mouth,” according to the affidavit.

When told to spit it out, Kiser reportedly spit a pill into the toilet, according to the affidavit.

Jail personnel “located two additional pills… that he had hidden in his sock,” according to the affidavit.

The two pills were identified as “buprenorphine hydrochloride… a schedule III controlled substance,” and the one spit out looked the same, according to the affidavit.

Kiser reportedly told jail personnel that he was given the drugs at a mental health treatment facility and he “saved them for later,” according to the affidavit.

According to a report published on the Centers for Disease Control and Prevention (CDC) website, “Buprenorphine is an effective medication for the treatment of opioid dependence.”

“In 2002, buprenorphine was approved by the Food and Drug Administration for the treatment (alone or in combination with naloxone) of opioid dependence,” according to the report. But, it is an opioid and, “similar to other opioids, buprenorphine produces euphoria and respiratory depression” — slow and ineffective breathing — an overdose complication.

Kiser was arrested on Monday, Dec. 4, for possession with intent to deliver, possession of a controlled substance, and tampering with evidence, after a woman at a mental health treatment facility reportedly told staff Kiser, who was also a patient there, had given her methamphetamine.

Kiser was charged in April with possession with intent to deliver, two counts of corruption of minors, endangering the welfare of children, reckless endangerment, possession of a weapon on school property, possession of a controlled substance, and possession of drug paraphernalia.

He was removed April 16 from the class he was teaching at Beaty-Warren Middle School by City of Warren police following an anonymous tip, according to the affidavit in that case.

Kiser was released from Warren County jail after posting bail on April 23.

A motion for a continuance in that case to the February 2020 trial term was granted in October.
