And some of the substances they cut it with will kill you faster, so they should legalize it.

Legalize meth?
Add more misery to the world!
It's not the the crap that they are cutting it with that makes it so addictive.

“Methamphetamine is one of the most addictive and neurotoxic drugs of abuse,” said Brookhaven chemist Joanna Fowler, lead author on the study. “It <B>produces large increases in dopamine</B>, a brain chemical associated with feelings of pleasure and reward, both by increasing dopamine’s release from nerve cells and by blocking its reuptake.”</DIV></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.elements4health.com/tracking-methamphetamine-in-the-brain.html">
Like cocaine, <B>methamphetamine entered the brain quickly</B>, a finding consistent with both drugs’ highly reinforcing effects.
