I feel like I must be completely insane. That or everybody else is. In the United States, the Bill of Rights guarantees all citizens the right to the pursuit of happiness. Is that correct? Then how can any drug be criminalized, when taking it falls under the pursuit of happiness? To me, this is as clear-cut as can be. Why doesn't the Bill of Rights guarantee US citizens the right to take any drug that genuinely makes them happy? Don't all prohibitionary laws contradict this right?
