Randomized Controlled TrialDelta9-tetrahydrocannabivarin testing may not have the sensitivity to detect marijuana use among individuals ingesting dronabinol.
The purpose of this study was to determine whether Delta(9)-tetrahydrocannabivarin (THCV), a plant cannabinoid, is a sensitive measure to detect recent marijuana use in cannabis dependent patients. It has been purported that smoking an illicit plant cannabis product will result in a positive THCV urinalysis, whereas the oral ingestion of therapeutic THC such as dronabinol will result in a negative THCV urinalysis, allowing for discrimination between pharmaceutical THC products and illicit marijuana products. ⋯ This suggests that THCV may not be a sensitive enough measure to detect recent marijuana use in all heavy marijuana users or that its absence may not discriminate between illicit marijuana use and oral ingestion of THC products such as dronabinol. We propose that the lack of THCV detection may be due to the variability of available cannabis strains smoked by marijuana users in community settings.

Long-term outcomes of office-based buprenorphine/naloxone maintenance therapy.
Buprenorphine/naloxone was approved by the FDA for office-based opioid maintenance therapy (OMT), with little long-term follow-up data from actual office-based practice. 18-Month outcome data on the office-based use of buprenorphine/naloxone (bup/nx) and the impact of socioeconomic status and other patient characteristics on the duration and clinical effects of bup/nx are reported. ⋯ Bup/nx-OMT is a viable treatment option and when coupled with a required abstinence oriented addiction counseling program is effective in promoting abstinence, self-help group attendance, occupational stability, and improved psychosocial outcomes in both low SES and high SES patient populations over an 18-42-month period.
