I am pretty sure the needles on the sidewalk is just there because everyone suffers from diabetes, right?

I think that, fortunately for most IT people like us, we can live in nice neighborhoods, where none of the social ills of drug-ridden neighbortlhoods affect us. So, we can support drug legalization, without being affected by the consequences.

> The model of inhumane prisons and death sentences?

Japan/Singapore imprisons much less people for drug crimes than the US - due to the USA's lenient laws on drugs (grey line vs. red line). The ill effects of drug use in japan is virtually non-existent.

You can moralize all you want, but it is a better system with less actual harm.
