First, MANY thanks to @DennisNoelKavanaghOffTwitter 🙏
Similar laws have been passed or are in the process of being passed in several other jurisdictions.
The worst (or "gold standard" as trans activists would have it) is the one in Victoria, Australia, which came into force in 2022 and which Scotland is looking at eagerly.
This is currently being reviewed by the Victorian Law Reform Commission, which should have reported by now as it said in February that it expected to publish "in sex months". Consultation on the Review ended in March.
Focused Review of How the Change or Suppression Practices Ban Is Working: Consultation Paper
Published on February 24, 2026
"The Attorney-General has asked the Victorian Law Reform Commission to review the operation and effectiveness of the Change or Suppression (Conversion) Practices Prohibition Act 2021.
The Act prohibits practices that aim to change or suppress a person’s sexual orientation or gender identity.
The review will focus on the terms of reference and examine how the current law is operating, whether it is effective in responding to change or suppression practices and how it might be improved. The purposes of the Act and the desirability of having criminal offences and a civil response scheme are not part of the review."

Answer:
Jurisdictions with enacted legislation
As of late 2026, sources such as Wikipedia’s compilation (drawing on primary legal texts and ILGA tracking) indicate roughly 28 countries have some form of restriction on conversion practices/therapy (attempts to change or suppress sexual orientation or gender identity). Scope varies widely: some impose criminal penalties on any person, others restrict only licensed medical or psychological professionals, and a further group impose indirect limits (e.g., prohibiting diagnoses based solely on sexual orientation or gender identity). Sub-national bans exist in federal systems. Numbers and classifications differ slightly across trackers because of definitional differences (criminal vs. professional-regulatory vs. diagnostic).
Full or criminal bans applying to any person (examples with approximate enactment/effective dates):
- Ecuador (2014 Penal Code provisions equating certain practices to torture).
- Malta (2016).
- Germany (2020; primarily minors, with limits on advertising and coerced adult cases).
- Canada (federal Criminal Code amendments effective January 2022; prior provincial measures from 2015 onward).
- France (2022).
- Greece (2022; mainly minors).
- New Zealand (2022).
- Spain (2023; national framework, with some regional variation and later challenges).
- Cyprus (2023).
- Iceland (2023).
- Belgium (2023).
- Norway (2023/2024).
- Portugal (2024).
- Mexico (federal 2024; many states earlier, from ~2020).
- Netherlands (legislation passed 2026, effective 1 January 2027; targets systematic/intrusive practices on minors or vulnerable adults, plus offering such services).
Restrictions mainly on medical/psychological professionals (examples):
- Brazil (Federal Council of Psychology resolutions from 1999, reinforced later).
- Albania (psychological association ban ~2020, effectively limiting practice).
- Chile (health ministry circulars and mental-health law provisions ~2021–2023).
- India, Israel, Taiwan, Vietnam (professional or regulatory limits in the 2010s–2020s).
- Greece is sometimes listed in both categories depending on the exact provisions.
Indirect or diagnostic bans (examples):
- Argentina (mental-health law provisions from ~2010 onward limiting diagnoses based solely on sexual orientation/identity).
- Uruguay, Fiji, Nauru, Samoa, Paraguay, parts of Switzerland (cantonal in some cases).
Sub-national examples:
-
Australia: Explicit criminal bans in Queensland (2020), Australian Capital Territory (2020/2021), Victoria (2021/2022), South Australia (2024/2025), New South Wales (2024/2025). Other states/territories lag or have different measures.
-
United States: As of 2024–2026 data, roughly 23 states plus the District of Columbia and Puerto Rico restrict licensed professionals from providing conversion practices to minors (earliest California and New Jersey ~2012–2013; later additions through the 2010s–2020s, including Minnesota, Michigan, Kentucky). Some states have funding restrictions or executive orders only; local ordinances exist in additional places. Several bans have faced First Amendment litigation (circuit split historically; Supreme Court activity noted in 2020s cases). No nationwide federal ban.
- Additional local or professional measures appear in parts of Switzerland and elsewhere.
Bills or proposals remain active in other places (e.g., some Austrian, Finnish, and UK processes; EU-level discussion). Classifications can shift with amendments, court rulings, or commencement decrees. Always check primary legislation for precise definitions, exemptions (e.g., exploratory therapy, religious speech, adult consent), penalties, and enforcement.
Published research on outcomes of the legislation itself
Direct evaluations of the effects of bans (as opposed to studies of the practices themselves) are limited. Most empirical work examines associations between exposure to conversion practices and later mental-health outcomes, or uses quasi-experimental designs around ban adoption. Causal claims require caution due to confounding, selection, measurement (often retrospective self-report), and the difficulty of isolating ban effects from broader social changes.
-
Studies of exposure to the practices: Multiple observational and systematic reviews link recalled exposure to higher rates of depression, PTSD symptoms, suicidality, and related harms. Examples include a 2024 Lancet Psychiatry cross-sectional analysis of U.S. sexual and gender minority adults (associations strongest for combined sexual-orientation and gender-identity efforts) and earlier difference-in-differences work on transgender youth using the 2015 U.S. Transgender Survey (elevated subsequent suicide-attempt and runaway risks after exposure, larger for younger ages). A large review of decades of literature (summarized in 2026 secondary reporting) found consistent patterns of association with harm across many studies, though individual-level effect sizes and causality remain debated; none demonstrated reliable, lasting change in orientation or identity under rigorous designs.
-
Studies of ban effects: Quasi-experimental work is scarcer. One difference-in-differences analysis of U.S. state bans found modest reductions in suicide mortality (driven mainly by young males) and improvements in self-reported mental health after adoption. Another stacked difference-in-differences study using Youth Risk Behavior Survey data associated bans with lower rates of seriously considering suicide among high-school students in the years after enactment (larger point estimates for LGB respondents in some specifications). A 2023 Journal of Health Economics paper on conversion-therapy exposure among transgender youth used a related design and reported substantial increases in attempt and runaway risks post-exposure. These designs attempt to address time trends and selection but remain subject to the usual limitations of observational policy evaluation (parallel-trends assumptions, heterogeneous enforcement, spillover).
- Broader context: Professional bodies (e.g., major psychological and medical associations) have long classified the practices as ineffective and potentially harmful on the basis of the cumulative evidence. Economic analyses have estimated substantial lifetime costs associated with harms. Enforcement data and prevalence estimates after bans are sparse and sometimes contested; some jurisdictions report continued informal or religious practices outside professional regulation.
Uncertainties remain significant: definitions of “conversion practices” differ across laws and studies; many bans focus on licensed providers and minors, leaving religious or adult voluntary settings less regulated; long-term population-level outcome data post-ban are still accumulating; and selection into studies or surveys can bias results. No high-quality randomized evidence exists (ethically infeasible), and null or mixed findings appear in some narrower or older literature. Independent replication and better administrative data would strengthen the evidence base.
