2020, as users, growers, and businesses could not agree on details. In June 2021, the Supreme Court in effect legalized the recreational use of cannabis. As of 2020, the COVID-19 pandemic interrupted supply chains from China to Mexico that provided the precursor chemicals to create fentanyl and methamphetamine, usually then exported to the U.S. Response to femicide and women's activism López Obrador's government has been criticized for failing to combat violence against women in Mexico and its high rate of femicide, which has risen dramatically since 2018. López Obrador has been accused of being slow to respond to women's demands to act on the issue of femicide. After a particularly well-publicized femicide of a kidnapped girl, women marches spiked nationally; as a result, the Head of Government of Mexico City, Claudia Sheinbaum (who is also a member of MORENA) announced new measures to prevent further femicides in the city, while López Obrador also announced a package of new measures to address the issue. Soon after, women's groups called for two days of action, a massive demonstration in Mexico City on International Women's Day (8 March), following by a strike on 9 March 2020. The Mexico City demonstration had some 80,000 participants. On Monday, 9 March 2020, the second day of action was marked by the absence of women at work, in class, shopping and other public activities. The "Day Without Us" (Día Sin Nosotras) was reported in the international press along with the previous day's demonstrations. Foreign policy Immigration and U.S. pressure The Trump administration in the U.S. pressed for building a wall on Mexico's northern border, and it also implemented measures attempting to stem the flow of migrants from Central America and other regions of the world. Although López Obrador expressed sympathy with migrants during his campaign, when the number of migrants surged, the U.S. threatened his government with trade sanctions, which led him to solidify the southern border. Government forces broke up migrant caravans heading through Mexico to the U.S. At the northern border, Mexico is now the stopping point for migrants sent back to Mexico by U.S. immigration authorities awaiting adjudication of their claims for asylum. Citing widespread corruption, López Obrador dismantled the Federal Police and incorporated elements of it into the recently created National Guard, which has been employed to stop Central American immigrants at the southern border.
