Since the Mexican state intensified its drug war in 2006 over 28,000 people have disappeared and over 150,000 have been murdered.
They walked out of their homes one day, never to return. Often no-one knows where they are, or whether they are dead or alive.
And for each person, someone is still searching.
María and her son Juan Carlos are part of a growing group of families who are calling for the legalisation, regulation and control of drugs.
This violent drug war has cost them everything. Four of María's sons and Juan Carlos's brothers have disappeared. They too now live in fear for their lives.
Drug prohibition is a global policy which is supposed to protect us. But as these stories underline, fighting the drug war does not keep children and families safe.
Drug-related violence affects everyone in Mexico and until the law changes, the next casualty of the drug war really could be anyone’s child. These families and communities who have lost everything to this war are calling for you to join them in their fight for legal regulation, to help save lives, and get drugs under control - not just in their country, but all over the world.
Take the pledge now and join our growing movement for change. In doing so, you are making a personal commitment to spread the word about howcurrent drug laws are causing unnecessary harm across the world to families and young people.
We are planning a series of campaigning activities both in Mexico, the UK and internationally. We will be in touch to keep you informed and tell you how you can get involved!
Drug policy reform will only happen if we keep talking about it, sharing the evidence with our friends and letting policy makers know how we feel. Get involved in the conversation!
