1920 1927 1970 s 2009
Mexico’s Department
of Public Sanitation
declares new legislation,
titled: “Dispositions on
the Cultivation and
Commerce of Products
that Degenerate the
Race.” This bans the
sale, production and
recreational use of
cannabis.
As US states begin to
criminalize the plant,
Mexico bans stock from
being exported over the
border.
1930 s
The US government
sponsors a scheme to spray
herbicides paraquat and
2,4-D over cannabis fi elds
in Mexico using helicopters.
Herbicide poisoning cases
begin to crop up in the US
after the tainted plants are
smuggled over the border.
President Felipe Calderón
decriminalizes small
amounts of cannabis and
cocaine for possession, in an
attempt for law enforcement
to focus on traffi ckers and
cartel bosses instead of
recreational users.
Drug cartels begin to
organise in Mexico to
smuggle alcohol into the
US during prohibition,
eventually expanding to
cannabis and other illegal
drugs using increasingly
violent means.
The deadline to legalize
cannabis is set for October
23. The fi nal draft of the bill
is unveiled on October 18.
The Mexican Supreme
Court makes it legal for
four members of SMART
(Society for Responsible
and Tolerant Personal Use)
to grow and consume their
own cannabis.
President Enrique Peña
Nieto legalizes cannabis
with under 1% THC for
medical use.
The Supreme Court ends
the cannabis prohibition
and moves to formally
legalize cannabis in the
near future. It hopes
legalization will improve
the country’s economy and
put a dent in the narco
traffi cking.
The vote has since been
delayed after missing the
deadline. Whether or not
Mexican authorities decide
to fulfi l the draft legislation
as law remains to be
seen. An announcement
is expected early the
following year.
