[pct-l] Polarpure

[David Hough reading PCT-L]

By the way, you can't buy Polarpure any more.    For years it was
packaged by a couple of local Sierra Club leaders, and had the great
advantage that it had infinite shelf life under any and all environmental
conditions, and no batteries required.    The only problem was that the
cap liner eventually deteriorated and leaked.

But the DEA noticed that elemental iodine, like practically every other
chemical known to man, can be used to make meth.    So they told the
Polarpure people they had to handle it as a controlled substance with
extensive documentation about how much they bought, from whom, and who
they sold it to, how much and when... it was just too much work for too
little reward, so they gave up.
