Subutex v. Suboxone Abuse Liability:
A study by investigators at Columbia University that seems to have received inadequate attention appeared in 2002. Bottom line: “... results demonstrate that both [Subutex and Suboxone] served as re-inforcers … and that they may have similar [intravenous] abuse liability in recently detoxified individuals who abuse heroin.” (Comer and Collins. 2002. J Pharmac Exp Therap 303(2):695-703)
We’re unaware of any data in the USA regarding the actual parenteral misuse of either medication (or, for that matter, misuse by oral consumption), but these findings would suggest that the primary consideration in deciding whether to use Subutex or Suboxone should be price.
