BISMARCK, N.D. (AP) — A clinic in Bismarck is offering treatments with ketamine, a drug growing in popularity around the country for help with depression and pain management.

The Bismarck Tribune reports that Jackie Materi, a certified registered nurse anesthetist and the operator of the Ketamine Care Clinic, administers the drug through a vein, with six infusions over a two-week period.

There are still concerns about widespread use of the drug for depression treatments because the length of the treatment's effectiveness varies from person to person and continued use can lead to negative side effects.

An American Psychiatric Association report published this year says only about 370 people with depression have taken the drug in clinical trials.

Ketamine is known as hallucinogenic party drug Special K, but it's widely found in operating rooms and hospitals for anesthesia.
