Entry gains the Hakkarainen & Kainulainen chapter (1972 Act as
first criminal-law drug control, read in full) and Finnish
Wikipedia (1966 criminalisation by decree, read via API), with
per-sentence citations. No scores or timelines changed. YAML OK,
history:test 40/40, full build passes. Stages only my hunk; the
1966 decree number/text remains the blocker for a full article.
See docs/research/history-finland-1966-decree-2026-10-26.md.
Cannabis was banned in 1966, and parliament voted narrowly in 1971 to make personal use a crime as well.[@1] The 1966 ban came by decree; drug control entered the criminal law only with the 1972 Narcotics Act.[@2,3]

+## Finland 1966: entry upgraded (no article yet)
+
+`finland-ban-1966` gains two sources and a clarifying second sentence, both
+cited per-sentence. New verified point: the 1966 ban came by decree, while
+drug control entered the criminal law only with the 1972 Narcotics Act.
+
+Sources actually read:
+
+- Pekka Hakkarainen & Heini Kainulainen, "Drug Use, Public Debate and
+ Increasing Pressures for a Drug Policy Reform in Finland" (Stockholm
+ University Press, 2021), full chapter PDF read via reference-global
+ mirror of DOI 10.16993/bbo.c: "drug control was included in the criminal
+ law for the first time at the beginning of the 1970s, when the 1972
+ Narcotics Act was enacted"; 1971 vote mechanics as already used in the
+ 1972 article. No 1966-decree substance in the chapter.
+- Finnish Wikipedia "Kannabis Suomessa" (read via API extracts):
+ "Kannabis kriminalisoitiin asetuksella Suomessa vuonna 1966."
+
+Still missing: the 1966 decree's number and text. Finlex's 1966 statute
+index is reachable but shows only the ten most-searched statutes; the
+/full search is client-rendered with no visible API; the treaty-series
+route guessed for the Single Convention implementation 404s. The decree
+number is the precise blocker for a Finland 1966 article.
+
+## Leads exhausted this pass (documented, not forced)
+
+- Duvall, The African Roots of Marijuana (Tunisia 1875): Google Books
+ snippet API reports the volume as not searchable. Article still needs
+ the book.
+- Chad/AEF 1926: The Conversation piece (read) links the Gallica folio for
+ the 1926 arrêté, but all Gallica endpoints (page text, SRU, IIIF) return
+ Cloudflare 403 to non-browser fetchers. The arrêté text stays unread.
+- Syria/Lebanon 1934: the same piece cites a 22 Nov 1934 L'Avenir du Tonkin
+ item via RetroNews, whose viewer shell loads but the article text sits
+ behind login. Our Syria 1943 (Quwatli) entry is unaffected.
+- Romania 1928: no primary or strong secondary surfaced.
+- Portugal 1926: Portuguese Wikipedia covers 2001 decriminalisation and the
+ empire (Goa, Brazil), nothing on 1926.
+- Finland side finds: OAPEN search migrated, Stockholm UP site 403s, TalTech
+ bachelor's thesis (Nykänen 2022) has no 1966 history — all correctly
+ passed over.
