The law sets out maximum “personal use” amounts for drugs, also including LSD and methamphetamine. People detained with those quantities will no longer face criminal prosecution; the law goes into effect on Friday.
Anyone caught with drug amounts under the personal-use limit will be encouraged to seek treatment, and for those caught a third time treatment is mandatory — although no penalties for noncompliance are specified.
Mexican authorities said the change only recognized the longstanding practice here of not prosecuting people caught with small amounts of drugs.
