Legal marijuana is taking a bite out of drug cartels' profits
<i>The cartels, of course, are adapting to the new reality. Seizure data appears to indicate that with marijuana profits tumbling, they're switching over to heroin and meth.</i><p>This is a really interesting development. There's always been this "gateway drug" argument around pot: once people start with marijuana, they'll move onto the harder stuff. I can imagine that there might be a correlation, but I expect that the causality is the other way around: once you break the law a bit for pot, and discover that it's really not a big deal, you assume that the other illegal drugs are probably fine too.<p>As marijuana becomes more and more legal in the US, it'll be interesting to see which way the causal link goes.
