Gradus Gravis OÜ, once a fully licensed psychiatric clinic, opened an office near the Tallinn Passenger Port — thus, being easily accessible to people of Helsinki —, offering prescriptions of certain controlled psychotropic drugs (most notably Subutex) to everybody who would pay a fee.
According to the Health Board, Milvi Koplus issued about 7000 prescriptions for Subutex within four months of 2003.
In connection with the affair, Estonian Medical Association cancelled membership of Rostislav Vassiljev and Milvi Koplus in 2007.
Due to the scheme becoming public, as well as reporting irregularities, the Estonian Office of Healthcare revoked the clinic's license in 2008.
However, according to enquiries to four apothecaries operating near the premises, the clinic issued at least 259 prescriptions for strong psychotropic medicine in the month after the revocation, 221 of them to citizens of Finland.
