It's not "crazy," it's capitalist politics.
The first US Dollar Bill and US Flag were made on hemp.
Hemp production (a low-THC variant of cannabis) was literally made law by the British for their colonies in the 1600s to make sails, rope, paper, and all sorts of textiles with the Virginia Assembly in 1619, requiring colonial farmers to grow it. This continued as psychoactive effects of THC were better realised and cannabis was turned into medicinal products, back when Heroin and Cocaine and everything else literally under the sun was still legal, and the public had zero problem with it.
Industrial hemp in America threatened the cotton industry, which was also part of the slave trade and the contemporary issues of the government's desire to grow itself and enslave its own people while villifying and enslaving all non-White Anglo-Saxon Protestants/Christians (not much has changed).
The term "marijuana" was repurposed (from use which referenced a wild tobacco plant, not even cannabis itself) in the first decade of the 1900s and used specifically to villify Mexicans—after the Mexican Revolution of 1910 when we saw more immigrants as whites continued to colonise the "States" and commit genocide against our indigenous people.
Port cities in the Gulf became a key area for spreading this bigotry and misonformation, where anyone to do with the West Indian trade—including Blacks of any heritage—was also targeted with this new weapon against the public; and even "Hindoos" fell in the proverbial crosshairs as it was used to villify "inferior races and social deviants" by bigots propped up by the Federal government (specifically by Henry Finger's proposition in 1913 when the first state cannabis prohibition law was passed in California—yes, California) who were essentially painting everyone against their war for establishing a caste system based on old-world imperialism as "about to go mad on marijuana and rape your wife and murder your family."
This became horrifyingly potent in the 20s and 30s after the government propped and boosted Harry J. Anslinger, the first commissioner of the nacient Federal Bureau of Narcotics, who insisted that marijuana led to “insanity, criminality, and death." By 1931, 29 states had outlawed it. Anslinger helped to boost George Hirliman to create the Reefer Madness videos and other propagandist bull-ish, which somehow cost $100,000—$2,022,647.48 today—to make some of the most bigoted, mis-informed films humanity has ever had the unfortunate experience of producing.
Congress passed the Marihuana Tax Act of 1937, essentially outlawing any part of its process and delegating its allowance to select few who paid an excise tax and were involved in select industries.
The 60s and 70s brought some calm locally while we raged some of the bloodiest, most ethically-twisted wars overseas and our nation tried to relax. Reports commissioned by Presidents John Kennedy and Lyndon Johnson found that cannabis ("marijuana") use did not induce violence, nor lead to use of heavier drugs. That was swiftly ignored by the all-time idiot Richard Nixon, who created the War On Drugs with Congress' Controlled Substance Act of 1970, and placed it as Schedule I—declaring it a high-risk for abuse and addiction while having zero medicinal properties whatsoever, villifying it indubitably. The rest of its history is within memory for most contemporary citizens, but the timeline is still ridiculous. Carter, Reagan, Ford, and Bush 1 all supported his War on our own people until 2000 when Clinton supported decriminalization in a Rolling Stone interview; Obama supported decriminalization in 2015.
In 1973, Texas made possession of 4 OUNCES or less a misdemeanor, and Oregon was already beginning to write outright decriminalization laws, reducing the fine to $100 for possession up to 1 oz. In 1978, New Mexico passed the Controlled Substances Therapeutic Research Act, becoming the first state to enact legislation recognizing the medical value of cannabis and completely contradicting the Nixon Administration's claims not even a decade after he began his racist, classist warmongering of our own citizenry.
In 1996, California wrote a state law legalizing medical "cannabis" via Prop 215, and over 10 states followed decriminalization ideology through 2012. Notably: Washington D.C. residents voted in favor of Initiative 59 to *legalize* it in 1998, but the Barr amendment blocked this until 2009. In 2005/09, Denver/Breckenridge residents voted to legalize it outright, and in 2010 Co!orado established the "Medical Marijuana Enforcement Division," further supporting the outwardly-racist misnomer from the first decade of the last century, despite all legal language referring to the actual (read: "real") plant "cannabis."
