The Gubmint also doesn't like admitting that it's spent trillions and trillions of dollars over the year fighting something that doesn't need fighting, causing most of the problems around it themselves, and putting thousands and thousands of people into the penal system for no reason whatsoever.
No reason whatsoever, that is, unless you are in one of the many industries that benefits from it being illegal...the industries that support the prison system, pharmaceutical companies, the AMA, the timber/pulp industry, and any other agricultural interest that grows stuff for textiles (like the cotton industry), or the tobacco industry.
Marijuana was made illegal to either protect some other industry that can't compete on the open market with hemp or marijuana production, or to create an industry that is there only because MJ is illegal.
As usual, follow the money...you'll almost always fine a big money industry or three that loves the "free market" so long as it benefits them, and hates the "free market" when it helps their competitors.
These people are also known as "Fuckin Hypocrites".
As an attorney destined to the fiery underworlds, there may be a glimmer of hope for your salvation yet. Tin foil & pink worms passed....
