How DARE They Regulate Cannabis

State by state the laws are changing, "Run From The Cure" finally forced the medical facts out into the open I guess. Finally. The science has been done for 40+ years! Of course the DEA is dragging it out (still Schedule 1), waiting for Big pHARMa to get ready for it. Monsanto is working on a nice little GMO cannabis plant for you!
I live in WA where med is legal (for some time now)and recreational just went online last week. Here you can grow 15 plants at one time...hold 24 oz. of dry, and are allowed to sell (for a donation, tax free) any unused portion to other med certified patients, show each other your papers and you can trade. The police are not seen here as monsters for the most part, one even helped me get my med (plants) out of a residence I was sharing when it turned sour...
Personally, I have very few small problems with the system I live under, but here is my question:
How can the same institutions that lied to us, actively kept the truth from us, locked up people trying to tell us the truth, locked up people who used cannabis, denied how many millions of people one of the most blessed substances on Earth, resulting in how many pre-mature deaths.....How can those institutions possibly find ANY standing to legislate anything about cannabis to We The People? In a court of the people they wouldn't be allowed to speak at all because they are proven LIARS.
BTW, just to head off you natural health haters, your opinion of me OR cannabis is not the issue here.

Peace, Babies.
