That depends on your perspective on "change". Since 1973, 12 state legislatures -- Alaska, California, Colorado, Maine, Minnesota, Mississippi, Nebraska, Nevada, New York, North Carolina, Ohio and Oregon -- have enacted versions of marijuana decriminalization. In each of these states, marijuana users no longer face jail time (nor in most cases, arrest or criminal records) for the possession or use of small amounts of marijuana.
My beef with the WOD related to marijuana is primarily that the feds should butt out of a states rights issue (10th amendment.) I am strongly constitutionalist - thus I support getting rid of leftist activist judges, for example. I see this as a constitutional issue, not that different than the 2nd amendment.
My secondary beef with the WOD related to pot is the cost. It is pretty damn expensive to put the officers on the street, hold trials (clogging the judicial system), putting people in prison (clogging the damn prisons), and losing the taxes and economic services of those imprisoned from the economy. Bottom line is that it it costs a bunch (about $7.5 Billion per year) to handle all of this. I would prefer the resources to be allocated elsewhere - like tighting up the southern border big time.
And no, I don't smoke. Smoking is bad for you and rots the lungs. That said, I don't care if someone else wants to rot their own lungs. And if they die at 65 from lung cancer instead of draining medical services for years and then dying at 90, well then I guess it save us tax money there also (cuts down on medicare/medicaid and social security.)
My beef with pot comes with those who produce to sell, those who distribute for profit, those who would abuse any real medical benefit it has for "other" purposes or try to hide behind "medical" use laws.
Beyond pot I have even less tolerance. When it comes to the manufacture and distribution of hard drugs I have no sympathy at all and would prefer to see the penalties far harsher then they currently are.
