Is weed legal in Mexico?

Can you provide some clarification on the legality of marijuana possession and use in Mexico? I understand that there have been some changes in the laws surrounding recreational and medicinal use of weed in recent years, but I'm unsure of the current status. Is it now legal to possess and consume marijuana for personal use in Mexico, or are there still restrictions in place? If so, what are the penalties for those who violate the law? Additionally, are there any specific requirements or conditions that must be met in order to legally use marijuana in Mexico?
