Carl Sagan was also an avid marijuana smoker who claimed marijuana gave him scientific insights.[2] The Barna Group found regarding atheism and morality that those who hold to the worldviews of atheism or agnosticism in America were more likely, than theists in America, to look upon the following behaviors as morally acceptable: illegal drug use; excessive drinking; sexual relationships outside of marriage; abortion; cohabitating with someone of opposite sex outside of marriage; obscene language; gambling; pornography and obscene sexual behavior; and engaging in homosexuality/bisexuality.[3]
