Why is marijuana really illegal in the US? Please see banned words below.?

There were several major factors, but it was primarily a racially charged decision and an effort to combat the changing culture in America. Marijuana began in Britain and the Americas as a well-liked treat for elites the world over; Queen Victoria, by some accounts Shakespeare, even George Washington were known to dabble in the dank, Washington even documented as an experimental grower of cannabis, with a keen interest in its medicinal properties.

Slavery and its aftermath brought with it black culture however, in which this 'rare treat' of the elite is their common pass-time. Cannabis was brought along with the slaves, and became a big part of post-slavery culture for blacks in America. In the racially charged post-slavery era, black people were frequently demonized by authorities. This demonization extended to black culture as well as black people, and the mixing of white and black people/culture was a serious taboo. Cannabis being an obvious and powerful lure to cross-cultural friendships/relationships, it was criminalized; both in an effort to 'defend white purity' and to provide authorities with a means through which to not just persecute but to actively prosecute black people.

While this policy was born out of racial tension and culture-conflict, powerful vested interests adamantly maintain it to this day; from pharmaceutical companies who absolutely do not want an easily grown, potent, relatively harmless euphoric on the market, to private prisons who rather like having massive populations of black workers imprisoned for petty drug crimes, to police-forces who want to avoid drops in funding should drug-war policies change.

The whole 'corporate anti-hemp conspiracy' is mostly nonsense.

the "incense of Satan":

"A man by the name of Rodrigo de Jerez sailed with Columbus on this same voyage, and in November of 1492, saw the natives smoking the same strange leaves that had been gifted. From them, he learned the art of smoking tobacco, and brought it back to Spain. His smoke exhalations frightened everyone, as they believed only the devil could blow smoke from his mouth, and the Spanish Inquisition captured and held him for seven years." 122 years later, tobacco saves Jamestown Colony from collapse.

the “devil’s drink”:

Should drinking alcohol be illegal? Even asking that question today seems absurd, but only 75 years ago it was illegal to drink alcohol in the United States.

I’m talking about Prohibition, of course, which lasted from 1920 to 1933. It was a massive fascist experiment that ended with waves of crime and corruption penetrating all levels of society, and the great depression.

5 years later, "Reefer makes darkies think they're as good as white men"

"New Billion-Dollar Crop appeared in the February 1938 issue of Popular Mechanics Magazine. Just as this article went to press The Marijuana Tax Act of 1937 took effect, which effectively killed the hemp industry." ($1 billion 1938 = $16.8 billion 2015)

and replaced it with a $15B/year "war on drugs"

You can thank: The Nylon Company. The U.S. military's "tests". Religion and the uneducated.

Nylon came out against it, because hemp rope was far superior in nearly every way, especially on fishing vessels.

The U.S. military wanted to weaponize it, and deemed it a detriment to our nation and its people. Religious folks don't know anything, and don't actual read up on anything, so if it's different then its against god's law. The uneducated, because they are uneducated and usually staunchly religious.

Marijuana is banned federally.

Because the govt decided that marijuana is illegal.. it's really arbitrary decision. For example, why is alcohol legal (during Prohibition, it was illegal actually)... it's all arbitrary decision.

So, you don't want to know why marijuana is illegal? Okay then.

Ever meet a pothead? That's all the answer you need.

F your banned words. Ill say anything I want.

simple. You cannot tax something that can be grown in someones closet.
