"Each adult is free to make lifestyle decisions without the intervention of the state." I agree in principle, but the reality is people's lifestyle choices can impact the state - whether it be they turn to the government health systems to help break their addictions (I write this from UK where we have socialised healthcare) or crime rates go up, and the state has to increase the police force. There are so many issues, but it's interesting to see a government taking a more progressive attitude towards casual marijuana use.
