The state has put the license of a Bellingham osteopathic physician and surgeon on probation for at least 41/2 years.
Gregory D. Sharp had been charged with unprofessional conduct for his treatment of 11 patients with chronic pain.
He was accused of violating the standard of care for the cases, which occurred from 2003 through 2010, according to the Washington state Board of Osteopathic Surgery and Medicine.
The probation allows Sharp to continue working, provided he follows strictures laid down by the state, including continuing education in the areas of ethics, pain management and record keeping.
His license could be suspended if he doesn't follow the probation requirements, according to the state.
In 2011, Sharp voluntarily surrendered his U.S. Drug Enforcement Administration registration. He also signed an agreement with the DEA, which required that he not treat opiate addiction, accept controlled substances from anyone or prescribe for himself or family members.
The state also said that while in Canada, he took ibogaine, which is illegal in the U.S., and paid for his daughter to receive it in the U.S. - both in 2009.
