Buprenorphine is a prescription painkiller that is illegal in Wisconsin if you don’t have a prescription. It is a narcotic and is controlled as such. Used to treat addictions to things like oxycodone and heroin, this opioid is highly-addictive when not taken as prescribed. Our firm handles all areas of criminal law, including firearm possession and drunk driving charges. OWI penalties in Wisconsin can be combined with possession charges for higher consequences.
