Reply #77: Not just big pharma, but all the major brewers and logging industry

The beer market would go belly-up as people would overwhelmingly select carb-free cannabis over diabetes-inducing alcohol as their recreational drug of choice.

On edit:
if marihuana (legal spelling by the way, google it) were legalized then industrial hemp would be legalized. That hurts chemical companies like AMD, it hurts logging for paper, it hurts cotton, and it hurts corn and other oil crops, as hemp is a superior material for these applications. In fact it was these industries (logging, chemical and industrial agriculture) who lobbied to criminalize marihuana in the first place.
