How Does Local Laws Work in Mexico?
Last verified: 2025-06 · Americas
1The Quick Answer
Drug possession for personal use is partially decriminalized, but firearms are strictly prohibited under any circumstances for tourists.
2What You Need to Know
Mexico has partially decriminalized small amounts of certain drugs for personal use (cannabis up to 5g, cocaine up to 0.5g), meaning personal possession may not lead to arrest, but it remains a legal grey area and is still federally illegal. Bringing any firearm or ammunition into Mexico — even accidentally — is a serious federal crime with mandatory prison sentences. Archaeological artifacts cannot be removed from the country. State and municipal laws vary significantly; always check local rules.
