Buprenorphine
From Drugwiki - Information about drugs, steroids and medicine
Buprenorphine is also used recreationally, typically by opioid users. Typical effects include analgesia, a sense of euphoria and increased verbal communication. Due to the high potency of tablet forms of buprenorphine, only a small amount of the drug need be ingested to achieve the desired effects. The buprenorphine preparation, Suboxone, comes in an orange-flavored tablet for sublingual administration. The taste of Suboxone is described by some to be very unpleasant. Possible explanations for this unpleasant taste could be the bitter taste of the buprenorphine itself, or that fact that it acts as a deterrent to abuse and was done intentionally by the pharmaceutical company, Reckitt Benckiser.
Buprenorphine abuse is very common in Scandinavia, especially in Finland and Sweden. In 2007, the authorities in Uppsala county in Sweden confiscated more buprenorphine than cocaine, ecstasy and GHB. In Finland, somewhere between 2005-2006, illegal use of Subutex (commonly intravenously) has preceeded the large number of amphetamine usage. Intravenous administration of dissolved Subutex pills and insufflation of pulverized pills are the most common ways of recreational buprenorphine use.
