'''Thebaine''' ('''paramorphine'''), also known as '''codeine methyl enol ether''', is an [[opiate]] [[alkaloid]], its name coming from the [[Greek language|Greek]] Θῆβαι, ''[[Thebes, Egypt|Thēbai]]'' (Thebes), an ancient city in [[Upper Egypt]]. A minor constituent of [[opium]], thebaine is chemically similar to both [[morphine]] and [[codeine]], but has stimulatory rather than depressant effects. At high doses, it causes convulsions similar to [[strychnine]] poisoning. The synthetic [[enantiomer]] (+)-thebaine does show analgesic effects apparently mediated through opioid receptors, unlike the inactive natural enantiomer (−)-thebaine.<ref name="aceto 1999">{{cite journal |author1=Aceto, M.

Thebaine is controlled under international law, is listed as a Class A drug under the [[Misuse of Drugs Act 1971]] in the United Kingdom, is controlled as an analog of a Schedule II drug per the [[Analog Act]] in the United States, and is controlled with its derivatives and salts, as a Schedule I substance of the [[Controlled Drugs and Substances Act]] in Canada.<ref>{{ cite web | url = http://laws-lois.justice.gc.ca/eng/acts/C-38.8/page-24.html#h-28 | title = Controlled Drugs and Substances Act | publisher = Government of Canada | work = Justice Laws Website | date = 2012-11-06 | access-date = 2014-01-12 | url-status = dead | archive-url = https://web.archive.org/web/20131122143804/http://laws-lois.justice.gc.ca/eng/acts/C-38.8/page-24.html#h-28 | archive-date = 2013-11-22 }}</ref> The 2013 US [[Drug Enforcement Administration]] (DEA) aggregate manufacturing quota for thebaine (ACSCN 9333) was unchanged from the previous year at 145 metric tons.

This alkaloid is biosynthetically related to [[salutaridine]], [[oripavine]], [[morphine]] and [[reticuline]].<ref>{{cite journal | last1 = Novak | first1 = B. | last2 = Hudlicky | first2 = T. | last3 = Reed | first3 = J. | last4 = Mulzer | first4 = J. | last5 = Trauner | first5 = D. | title = Morphine Synthesis and Biosynthesis-An Update | journal = Current Organic Chemistry | year = 2000 | volume = 4 | issue = 3 | pages = 343–62 | doi = 10.2174/1385272003376292 | url = http://brocku.ca/mathematics-science/departments-and-centres/chemistry/faculty/Hudlicky/CurrOrgChem-2000-4-343.pdf | url-status = live | archive-url = https://web.archive.org/web/20120619063224/http://brocku.ca/mathematics-science/departments-and-centres/chemistry/faculty/Hudlicky/CurrOrgChem-2000-4-343.pdf | archive-date = 2012-06-19 | citeseerx = 10.1.1.515.9096 }}</ref>
