         | The highest blood lead levels are seen in children living in
         | denser population areas at or below poverty thresholds. Homes
         | in these largely urban, low-income areas are disproportionately
         | built before 1978 and subject inhabiting children to a
         | significantly higher lead exposure risk. In 2014, it was
         | estimated that 90 percent of all DC homes were built before
         | 1978.
         | 
         | Despite Baltimore leading the charge to inform the public
         | concerning the risks of environmental exposure to lead by
         | banning lead-based paint (but not plumbing or other
         | construction products) in 1951 following a clinical study from
         | Johns Hopkins University, many Baltimoreans, primarily Black,
         | continue to face excessive exposure to lead. The US would not
         | follow Baltimore's example and ban lead-based paint until 1978,
         | because lead lobbyists continued to disrupt regulation efforts.
         | 
         | Lead remediation is an expensive process and even with programs
         | that help or completely cover the costs, many people may not be
         | aware of the programs to take advantage of them.
         |

         | the Black population.

             | cutting criminal penalties, he had to reassure his right

             | but...a medical doctor (Jerry Jaffe, a sweet, bookish man

             | Harry Anslinger, the first commissioner of the Federal
             | Bureau of Narcotics (an early predecessor of the DEA), was
             | one of the driving forces behind pot prohibition. He pushed
             | it for explicitly racist reasons, saying, "Reefer makes
             | darkies think they're as good as white men," and:
             | 
             | "There are 100,000 total marijuana smokers in the U.S., and
             | most are Negroes, Hispanics, Filipinos and entertainers.
             | Their Satanic music, jazz and swing result from marijuana
             | use. This marijuana causes white women to seek sexual
             | relations with Negroes, entertainers and any others."
             | 
             | The main reason to prohibit marijuana, he said was "its
             | effect on the degenerate races." (And god forbid women
             | should sleep with entertainers!)

         | arbitrarily control for that, but not for other factors that
         | influence IQ such as maternal care? It's complicated to decide
         | what to control for, but the _law_ is absolutely not the place
         | go to make that decision.
