First, you have to know what amparo means.
From http://www.borderlandbeat.com/2019/08/mexico-court-rules-use-is-ok-cocaine.html:
A judge from Mexico City granted two amparos that order the Federal Commission for the Protection against Health Risks (Cofepris) to authorize the possession, transport, use and use of cocaine, excluding the all trade act
The amparos were granted to members of the Mexico United Against Crime organization. “Cocaine use in adults does not pose a significant health risk, except in the case that it is used chronically and excessively,” said Víctor Luna Escobedo, Tenth District Judge in Administrative Matters.
“This moderate consumption is up to half a gram daily, it must be in private spaces, without the presence of minors, without being able to take to work, drive vehicles, incite third parties or handle dangerous instruments or machines.
“Cocaine intake or consumption may have different purposes, including stress relief, intensification of perceptions or the desire for new personal and spiritual experiences”
