A Colusa doctor and his son are accused of selling prescription pills to drug dealers and possessing close to 40 pounds of marijuana, according to a DEA affidavit that was unsealed Wednesday.
The complaint against Dr. Andrew Larsen and his son Cameron Larsen says the doctor abused his medical license to push prescription opiate pain killers, as well as marijuana, which were found in abundance at their Princeton, Calif. home.
"Larsen prescribes controlled substances (narcotic painkillers) to drug dealers and excessive quantities to out-of-state and local patients," the complaint said.
The complaint was filed as a result of a long investigation by the DEA, Department of Justice, US Department of Health and Human Services, Office of Inspector General, US Postal Inpsections Service, the California Medical Board, and the California Bureau of Medi-Cal Fraud and Elder Abuse.
The DEA claims Dr. Larsen mostly prescribed powerful pain pills, such as oxycodone, methadone, hydrocodone and morphine.
Between Aug. 16, 2012 and Aug. 16, 2013, Larsen prescribed nearly 5,500 controlled substance prescriptions, 98 percent of those prescriptions were schedule 2 or 3 drugs.
Federal agents served search warrants at Dr. Larsen's Colusa medical practice on Nov. 13, and followed up with a search of the Princeton home he shares with his son.
When agents searched their Dodge Road home, they found pills, guns and pot spread throughout the house. A safe in Dr. Larsen's bedroom contained three rifles, two handguns, two pounds of marijuana, various prescription drugs and $6,000 in cash. A safe found in Cameron Larsen's room revealed a lot more pot and another handgun.
Nearly 40 pounds of marijuana were found in the home.
Both Larsens face federal criminal charges of possession with intent to distribute oxycodone, possession with intent to distribute less than 50 kilograms of marijuana, use of a firearm in a drug trafficking offense and maintaining a drug involved premises.
On top of the criminal charges, the California Medical Board suspended Andrew Larsen's medical license for 30 days in November and put him on probation for five years.
The complaint filed the by the Medical Board last year accuses Larsen of gross negligence in the care of at least seven patients, mostly for keeping patients on a regiment of high-dose opiates without proper documentation or supervision. In almost every case, patients were receiving doses well over the recommendation, sometimes over 40 times the recommended dosage. Several of these patients were known to be substance abusers and should not have been on high-dose opiate therapy at all.
The investigation by the Medical Board also shows that Larsen kept shoddy records. In one case, medical records were hand written and barely legible. In another case, Larsen is accused of copying and pasting the exact same information and narrative for each of the patient's visits.
Many of Larsen's patients were known to request early refills for opiates, claiming they had lost their prescriptions. Another patient tested negative for the drugs he was being prescribed, suggesting the patient was selling or giving the medication to other people. That patient tested positive for methamphetamine.
It's unknown if Larsen's arrest will trigger another Medical Board investigation or will result in tougher sanctions against him.
