Money did speak... 90 years ago when interested (and wealthy) parties saw to it that weed be made illegal. It has been banned ever since and so there hasn't been almost any opportunity for the money in the marijuana business to do any speaking. That is the real reason that pharma businesses lobby against legalization of it. Not just because it would hurt their business directly (lost sales) but because weed businesses would be able to legally lobby against pharama's interests.
