Americans will only respond to capitalism. We have to MARKET cannabis to them.

If we can make more people WANT cannabis, then more people will vote to legalize it! We have the power of the internet, and the strength of facts and truth. We can convince 90% of Americans that weed is safe and should be legal.

TL;DR: Don't convince people that weed should be legal, convince people that they should want it too. Only then will we get the support.
