I don't think the US has much to lose by legalising recreational MJ use. Aside from the tax income (mind you alcohol tax will drop) there should be other benefits such as reductions in violent crimes, meaning less stress on law inforcement and paramedics, as well as less congested courtrooms.
Also RB, just want to point out that you missed the part where we own 9% of Gibio! $50m MC still cheap as chips!
