Okay but it's really not something that'll put "huge corrupt industries" out of business. I doubt paper companies lobby for marijuana illegalization very much. Or cigarette companies. Who would be affected?
I can't post an actual real source because I can't find it anymore but it can basically damage oil/tobacco/alcohol/paper and other chemical corporations.
Edit: And yes maybe I was exaggerating when I said it could put them out of business but it can affect them a lot.
Why don't you tell us everything you know about why marijuana is bad here?
Come on man, don't hold a grudge like that.
