Smart people are more likely to deal with new things and try them. Those new things seem to include drugs. Why?…While “the use of opium dates back to about 5,000 years ago…other psychoactive drugs are ‘chemical’ (pharmacological); they require modern chemistry to manufacture.” Psychoactive drugs, therefore, are evolutionarily pretty new to humans. Which means that smart people, according to the theory, will be more likely to take psychoactive drugs. — The Atlantic Wire, “Smart People Do More Drugs–Because of Evolution“, November 2, 2010.
