Robertjohnsn3090 is essentially correct. Our government does NOT care about our well being. If Uncle Sam cared about our health, we'd have national health care. Instead,what do we have? Bombs. Drones. Toxic military manufacturing byproducts in city water across our nation.
What's legal? Cigarettes-just the bystander smoke kills 200,000 of us a year. Alcohol-kills adults,destroys babies brains,causes genetic damage that lasts for generations(Fetal Alcohol Syndrome) Instead of Cannabis for seizures & anxiety, Uncle Sam wants his vets to take Xanax & Valium or other benzodiazepines, all of which kill your immune system , make you paranoid & unable to remember anything-but hey,BIG PHARMA has patents,so they make money! Even the generics make money.
The feds won't ever admit that weed is therapeutic. They want those sweet drug bust asset confiscation goodies. The feds are always raiding state legal weed pharmacies. It's about the fines,property, bail,probation fees-pot busts are a real gravy train for law enforcement. They don't want to give it up.
Between the lobbyists for casinos(which fear weed users won't go out & gamble),Tobacco & alcohol, and pharmaceutical lobbyists, and the intimidation factor of law enforcement really makes legalization a long shot.Before the govt. Will let it become legal,they'd have to determine that it's worth it financially because they don't want to fat gravy train to stop.
