Conservativism "worships the law"?!! Bwaahahahahahaha! :-) That's hilarious!
"The Law" in the United States is the Constitution. The 10th Amendment to the Constitution absolutely forbids federal regulation of any drug. (That's why a Constitutional amendment was required to regulate alcohol.)
Conservatives shamelessly ignore The Law when they support federal criminalization of ANY drug (absent a Constitutional amendment).
Legalization of ALL drugs (at least at the federal level)...it's The Law. (Elected/appointed) conservatives certainly don't "worship" The Law. They don't even follow it! And conservatives among The People certainly don't insist that the people they elect follow The Law. If they did, they'd vote Libertarian (at the federal level, at minimum).
