A county attorney's office in Minnesota expects to file charges soon, following completion of an investigation into Vireo Health's alleged transport of $500,000 of medical marijuana products from Minnesota to New York.

No further information was available Thursday. Brian Lutes, an assistant county attorney in Wright County, Minn., said details would be forthcoming.

In a statement, Vireo said it has not been the target of Minnesota investigators' probe.

"While we are aware of an investigation by the Wright County Attorney, we have no information as to its status except that we have been told our company is NOT a focus of the investigation," the company said in a statement.

The company operates in both states. Vireo Health of New York grows marijuana and produces medicine at a manufacturing plant in Perth, Fulton County, and sells its products from four locations statewide, including one in Colonie.

According to a search warrant filed with a Minnesota court in May, investigators sought to determine whether Vireo transported the products from Minnesota to its Fulton County plant in December 2015 because managers believed plants grown in New York were inadequate for medical marijuana production. New York regulators expected the five medical marijuana companies selected to participate in its then-nascent program to have products available for sale to qualifying New Yorkers by January 2016.

The former chief scientific officer at Minnesota Medical Solutions, Vireo's affiliate in that state, told investigators he was directed to identify cannabis oils in Minnesota that would "rescue New York," according to court documents filed by the Minnesota Bureau of Criminal Apprehension.

Because the federal government considers the drug illegal — even for medicinal purposes — it is unlawful to transport medical marijuana products across state lines. New York required companies to conduct all parts of their operation, from growing the plants to selling the medicines, within the state.

In a statement to the Times Union in June, Vireo said the claims against it were made by a disgruntled employee. After being fired in April, the employee intentionally tampered with laboratory machinery and indicated he would harm the business, according to Vireo.
