Just to go against the trend and say something good about the Taliban: it was fairly widely reported earlier this year that the Taliban cracked down on opium cultivation, banning it on the grounds that it is "un-Islamic". This link contains a copy of the NYT article that has favorable quotes about the Taliban's drug policy from the DEA officials and Colin Powell.

I've heard a number of "talking heads" on TV, including a few senators, talk about the Afghanistan/Heroin link over the last week. But while the Taliban obviously have a number of fairly awful policies, this doesn't seem to be one of them.
