Let me make clear that my position is not personal. I have no interest in using pot. I do think, though, that marijuana is no worse for society than bourbon. I think we should legalize, regulate, and tax marijuana production the same way we do alcohol. I have maintained this position for some years.
What is new now is that 50% of Americans agree. Moreover, only old people are strongly against it. Coming generations are clearly in favor, as this list of the percent supporting marijuana legalization by age group shows:
50 - 64: 49% (this is my age group)
30 - 49: 56%
18 - 29: 62%
I saw we tax pot to fight crack.
