Recreational Drugs should be Legalized in the United States of America

Unfortunately my opponents logic is flawed. Every example he offers the possible harm caused to others as justification to criminalize the act. The act of using drugs itself doesn't cause the harm, just the "possible" effects. I say criminalize the acts against others....Criminalize murder, blowing second hand smoke in someone's face, drug use by minors, but don't criminalize adult regulated drug use. We can regulate this use but not criminalize this use. My opponent asks if I am debating for all the harmful effects of drug use, I am not. There is a Natural Law or God's Law, if you subscribe. This law is undeniable whatever you want to call it. This is the law of natural consequences. If I drink excessively all day the natural consequence of over drinking will happen. Does man need to step in and make more strict laws than what Nature/GOD has already provided? Both the man who denies the self evident law of Nature/GOD by drinking to much is just as foolish as the man who doesn't think the Natural law is enough. My opponent is the man who believes Nature is not enough punishment for the drunkard/drug addict. My opponent believes that we should also step in and put the drug addict in jail in addition to the Natural Law. I believe this is contrary to LOGIC, many religions including CHRISTIANITY, and the United States Constitution and Bill of Rights. "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty, and the pursuit of happiness." It is important to note that I'm not suggesting you have to believe in a God or Creator to understand this. I'm simply suggesting that this law exist and is self evident. It can not be denied. An atheist could easily replace God or Creator with Nature or Natural Law. I believe the founders of the USofA understood "Creator" as this. The founders are referring to this natural, self-evident law. This law gives Rights naturally and man doesn't need to regulate them. Regulating them is against Nature/God. The only responsibility of man is to protect every ones Liberty so as to allow Nature/Gods law to govern. Murder is a denial of Liberty and should be regulated. Smoking pot in your basement is NOT. Gods/Natures Law doesn't need man to step in and compliment it, The Law is perfectly capable of carrying out its own discipline. Smoke Crack and the consequences will come, touch a hot stove and feel the pain. Should man make it illegal to burn yourself? I will agree with my opponent on any act that takes away another persons Liberties directly should be in violation of the law and disciplined accordingly. What about the man sitting in his house all day smoking Crack. How has that man violated anothers Liberty directly? How can we justify making that act criminal and punishable by law? We can't unless we start making stuff about about how he MIGHT do this or that. I agree with my opponent on every negative side effect of drugs and that they may even help cause crime but this is no argument on denying liberty and freedom for all. What right is given us that we should take away anothers right to do what they want with their body if it doesn't violate or freedoms?
