Could you elaborate why you think failing to take drugs will lead to extinction of the human species within a generation (as we would see without sex)? Why would there be an evolutionary pressure towards taking drugs?

for example. there are around 1.6 billion people who call themselves muslims and they don't touch alcohol and haven't done so for around 1500 years. is that "fighting evolution" ? muslims have grown to not like alcohol, peer pressure, religion and what not. the result? people don't sneak out and have a swig. its just understood that no alcohol means no alcohol.

i am assuming that is the long term goals of new zealand

Did you even read my comment?
