Minnesota law enforcement authorities say Wednesday, September 25, that they have confiscated 75,000 vaping cartridges in Anoka County, north of Minneapolis.

A serious vaping-linked lung illness is recently becoming a health concern.

While the cause of the lung illness is unknown, authorities are investigating black market vaping products.

Officials from the Department of Public Safety say the confiscated vaping products have been transported from out of state for delivery in Minnesota.

Drug Coordinator Brian Marquart expresses concern about these products.

"We have no idea what is in these cartridges and we will again, like the health department and everybody else, caution anybody that is using these products, you do not know what is in them."

The Centers of Disease Control and Prevention (or CDC) reports a tally of 530 confirmed and probable cases of the lung illness that has already claimed nine lives.

CDC Principal Deputy Secretary Dr. Anne Schuchat says more young people are affected: “One half of all cases are less than 25 years old."

Daniel Huff from the Minnesota Department of Public Health says, "We currently have Minnesota children who are on mechanical ventilation due to this vaping injury.”

New Hope Police Department Chief Tim Fournier urges authorities to consider the situation carefully before making further decisions.

The centers are expecting the number of reported vaping-related illnesses in the U.S. to increase. However, not much is known, as the investigation is continuing, says Schuchat.

She advises the public to refrain from vaping or using e-cigarette products.
