Hopefully this is just the beginning of an eventual nationwide adoption. I don't smoke but I've never understood why we can't legalize it and tax it similar to how we do with alcohol. This is a good first step.
The same should happen for prostitution. More senseless restrictions for a victimless crime.
Prosititution is not even close to a victimless crime, considering the overall amount of people damaged by the sex trade. Legalizing it might help curb that but it wouldnt eliminate it.
Think about what you just said. The "sex trade" is kidnapping, forced imprisonment and rape. Granted those are not victimless crimes, but those are not prostitution, they are coercion. And coercion is wrong and a crime no matter the subject. And as you pointed out, the sex trade is more prevalent because prostitution is illegal.
If two adults agree without coercion to trade money for sex, that is a victimless crime and preposterous for government to be involved.
