After Prohibition ended in 1933, the United States faced a political and
bureaucratic problem: federal agencies built to police alcohol needed a new
justification for their existence.
At the same time, Jim Crow ideology remained firmly embedded in American law and
culture. While formal bans on racial mixing focused on marriage and intimacy,
racial control also operated through criminal law and moral panic.
Harry J. Anslinger, head of the newly empowered Federal Bureau of Narcotics,
became the central figure in redirecting enforcement energy toward marijuana.
Anslinger framed cannabis not as a public health issue, but as a social and
racial threat.
In his public statements and testimony, Anslinger explicitly associated
marijuana use with marginalized groups, including Black Americans, Mexican
immigrants, and South Asian (often referred to at the time as “Hindus”).
He claimed that marijuana caused violence, sexual transgression, and defiance
of social norms, particularly across racial lines.
Marijuana had entered U.S. port cities and border regions through labor and
trade networks, including Black dock workers, Mexican agricultural laborers,
and immigrant communities. Rather than addressing labor conditions or public
health, Anslinger and his allies used drug policy as a tool of social control.
The Marihuana Tax Act of 1937 did not ban marijuana outright, but made its use
and possession legally perilous, selectively enforced, and stigmatized.
Enforcement disproportionately targeted Black and brown communities, reinforcing
existing racial hierarchies without explicitly invoking race in the statute.
This strategy mirrored Jim Crow logic:
where anti-miscegenation laws controlled who could form families,
drug laws controlled who could be criminalized, surveilled, and excluded from
economic and civic life.
In both cases, the law was used not merely to regulate behavior, but to preserve
a racial order threatened by social change following Prohibition, migration,
and labor mobility.
Bottom line:
As Jim Crow policed intimacy to prevent racial mixing, early marijuana laws
policed substances to control racialized populations. Both relied on moral panic,
selective enforcement, and the appearance of neutrality to enforce inequality
through law.
Jim Crow laws included explicit prohibitions against racial mixing, known as
anti-miscegenation laws.
“Miscegenation” laws were state laws that criminalized marriage, sexual
relationships, and sometimes even cohabitation between people classified as
belonging to different races, most commonly between white people and Black
people, but also affecting Native Americans, Asians, and others depending on
the state.
These laws existed primarily in Southern states but were also present in parts
of the Midwest and West. They were justified by claims of maintaining “racial
purity” and social order and were enforced through criminal penalties,
annulments of marriages, and social intimidation.
Anti-miscegenation laws were a core component of the Jim Crow system, alongside
segregation in schools, housing, transportation, employment, and public life.
Their purpose was to reinforce white supremacy by legally enforcing racial
hierarchies and preventing family bonds that might challenge those hierarchies.
The U.S. Supreme Court upheld such laws for decades. In 1883, the Court ruled
that states could regulate marriage, and in 1887, it upheld bans on interracial
marriage in Pace v. Alabama, asserting that equal punishment of both races did
not constitute discrimination.
These laws remained in effect until 1967, when the Supreme Court unanimously
struck them down in Loving v. Virginia. The Court ruled that bans on interracial
marriage violated both the Equal Protection Clause and the Due Process Clause of
the Fourteenth Amendment.
Loving v. Virginia formally ended all remaining anti-miscegenation laws in the
United States, affirming that marriage is a fundamental right and that racial
classification has no legitimate place in determining whom a person may marry.
Bottom line:
Jim Crow laws did not merely separate races in public spaces; they sought to
control intimacy, family formation, and reproduction in order to preserve a
racial caste system through law.
