The criminal market that has developed through the illicit marketing of marijuana has now become a justification for the decriminalization of this substance. It is well known that we Mexicans are in the middle of what is called the “war on drugs.” There is violence and insecurity in our country; there is an underground market for illegal substances; and drug-related incarceration carries a high economic cost. But I am writing to you, Mr. President, as a non-governmental actor, as a student, that I am concerned about the consequences of the decriminalization of marijuana not on our economy, but on the well-being of our citizens. I am writing on behalf of a group of Mexican students who oppose the legalization of drugs like marijuana. Throughout history, utopian models have functioned as structures for how society should function. These are ideas that help explain the world and better understand what reality might be like. As popular as they were in the era of Renaissance humanism, let me tell you about my utopian proposal for a drug-free country today. As idealistic as this may sound, I believe it is worth a try. What we need, I believe, is a pact for free-thinking citizens when it comes to drugs. We must enable our citizens to think rationally, to take responsibility for their actions and not have their judgment clouded by any substance. Utopically, if we could get everyone to sign the pact, and have everyone truly believe in it in their daily lives, there could be a cultural shift in our country that could address drug addiction. We don't need millions of signatures; we need millions of people determined not to use drugs. Let's stop talking nonsense and explain what it can...... middle of paper ......tance. The problem of drug trafficking in our country goes deeper than the marijuana trade. It is much more than a process of buying and selling illegal substances. The product it offers has exceeded its limits in the market. Decriminalizing marijuana is not the solution to violence and citizen safety. Drug trafficking now relies on established commercial activities; it is an entire organization of money laundering, violence and conflict. Legalizing these substances will not turn drug dealers into businessmen and drug users into buyers. Once drugs are regulated by the state, that established business will likely look for another product to sell, but they won't just be part of the state-regulated economy. What we need is citizen participation in rejecting illegal substances. We need drug-free thinking citizens. We need rational citizens..
