Doesn't matter. Most of us were growing and smoking long before it was legal and will continue to do so regardless if it's legal or not. At least I will, I pay very little attention to what the government does or tells me. For the most part I live my life exactly how I want.
If murder and rape were legalized tomorrow, I'm not going to kill or rape anyone, because that's not what I do. The same thinking can be applied to marijuana laws and every other law. With the exception of the IRS, I pay no mind to government laws.
I wouldn't let a stranger on the streets come up to me and tell me how to live my life. Politicians are strangers, I don't know them and have never met them in my life. They don't pay my bills or do anything for me, thus I don't pay their demands on how to life my life any mind anymore than I would a crazy homeless person giving me orders of living life.
Furthermore, both parties are scum. Republicans want to tell people who they can fuck, marry, what kind of drugs they can do. Democrats want to dictate what kind of firearms, if any, we are allowed to have and constantly trying to extort more money from people under the guise of helping the poor. Politicians in general are pieces of shit, the lot of them.
