Both are shaped by radical LGBTQ activism and questionable evidence.

Over the past decade, North America embraced two disastrous public health movements: pediatric gender medicine and “harm reduction” for drug use. Though seemingly unrelated, these movements are actually ideological siblings. Both were profoundly shaped by extremist LGBTQ activism, and both have produced grievous harms by prioritizing ideology over high-quality scientific evidence.

While harm reductionists are known today for championing interventions that supposedly minimize the negative effects of drug consumption, their movement has always been connected to radical “queer” activism. This alliance began during the 1980s AIDS crisis, when some LGBTQ activists, hoping to reduce HIV infections, partnered with addicts and drug-reform advocates to run underground needle exchanges.

In the early 2000s, after the North American AIDS epidemic was brought under control, many HIV organizations maintained their relevance (and funding) by pivoting to addiction issues. Despite having no background in addiction medicine, their experience with drug users in the context of infectious diseases helped them position themselves as domain experts.

These organizations tended to conceptualize addiction as an incurable infection—akin to AIDS or Hepatitis C—and as a permanent disability. They were heavily staffed by progressives who, influenced by radical theory, saw addicts as a persecuted minority group. According to them, drug use itself was not the real problem—only society’s “moralizing” norms.

These factors drove many HIV organizations to lobby aggressively for harm reduction at the expense of recovery-oriented care. Their efforts proved highly successful in Canada, where I am based, as HIV researchers were a driving force behind the implementation of supervised consumption sites and “safer supply” (free, government-supplied recreational drugs for addicts).

From the 2010s onward, the association between harm reductionism and queer radicalism only strengthened, thanks to the popularization of “intersectional” social justice activism that emphasized overlapping forms of societal oppression. Progressive advocates demanded that “marginalized” groups, including drug addicts and the LGBTQ community, show enthusiastic solidarity with one another.

These two activist camps sometimes worked on the same issues. For example, the gay community is struggling with a silent epidemic of “chemsex” (a dangerous combination of drugs and anonymous sex), which harm reductionists and queer theorists collaboratively whitewash as a “life-affirming cultural practice” that fosters “belonging.”

For the most part, though, the alliance has been characterized by shared tones and tactics—and bad epistemology. Both groups deploy politicized, low-quality research produced by ideologically driven activist-researchers. The “evidence-base” for pediatric gender medicine, for example, consists of a large number of methodologically weak studies. These often use small, non-representative samples to justify specious claims about positive outcomes. Similarly, harm reduction researchers regularly conduct semi-structured interviews with small groups of drug users. Ignoring obvious limitations, they treat this testimony as objective evidence that pro-drug policies work or are desirable.

Gender clinicians and harm reductionists are also averse to politically inconvenient data. Gender clinicians have failed to track  long-term patient outcomes for medically transitioned children. In some cases, they have shunned detransitioners and excluded them from their research. Harm reductionists have conspicuously ignored the input of former addicts, who generally oppose laissez-faire drug policies, and of non-addict community members who live near harm-reduction sites.

Both fields have inflated the benefits of their interventions while concealing grievous harms. Many vulnerable children, whose gender dysphoria otherwise might have resolved naturally, were chemically castrated and given unnecessary surgeries. In parallel, supervised consumption sites and “safer supply” entrenched addiction, normalized public drug use, flooded communities with opioids, and worsened public disorder—all without saving lives.

In both domains, some experts warned about poor research practices and unmeasured harms but were silenced by activists and ideologically captured institutions. In 2015, one of Canada’s leading sexologists, Kenneth Zucker, was fired from the gender clinic he had led for decades because he opposed automatically affirming young trans-identifying patients. Analogously, dozens of Canadian health-care professionals have told me that they feared publicly criticizing aspects of the harm-reduction movement. They thought doing so could invite activist harassment while jeopardizing their jobs and grants.

By bullying critics into silence, radical activists manufactured false consensus around their projects. The harm reductionists insist, against the evidence, that safer supply saves lives. Their idea of “evidence-based policymaking” amounts to giving addicts whatever they ask for. “The science is settled!” shout the supporters of pediatric gender medicine, though several systematic reviews proved it was not.

Both movements have faced a backlash in recent years. Jurisdictions throughout the world are, thankfully, curtailing irreversible medical procedures for gender-confused youth and shifting toward a psychotherapy-based “wait and see” approach. Drug decriminalization and safer supply are mostly dead in North America and have been increasingly disavowed by once-supportive political leaders.

Harm reductionists and queer activists are trying to salvage their broken experiments, occasionally by drawing explicit parallels between their twin movements. A 2025 paper published in the International Journal of Drug Policy, for example, asserts that “efforts to control, repress, and punish drug use and queer and trans existence are rising as right-wing extremism becomes increasingly mainstream.” As such, there is an urgent need to “cultivate shared solidarity and action . . . whether by attending protests, contacting elected officials, or vocally defending these groups in hostile spaces.”

How should critics respond? They should agree with their opponents that these two radical movements are linked—and emphasize that this is, in fact, a bad thing. Large swathes of the public understand that chemically and surgically altering vulnerable children is harmful, and that addicts shouldn’t be allowed to commandeer public spaces. Helping more people grasp why these phenomena arose concurrently could help consolidate public support for reform and facilitate a return to more restrained policies.
