How?
5.356 million people live in colorado based on 2014 consensus. That's pretty wide-spread
Marijuana has more positives than recreational usage, I was just stating one of the benefits.
Do you mean smoking nicotine or smoking marijuana?
Smoking kills, reduction in usage of smoking products = success
Colorado is not the world
If it's not for recreational usage and it actually helps people benefit their health then i'm all for it.
Both nicotine and marijuana, any drug.
Also it's not the nicotine in cigarettes that was causing the harm (other than causing an addiction), generally breating in fumes from anything is bad.
