Police prosecute over 800,000 Americans annually for violating state marijuana laws. The penalties for those busted and convicted vary greatly, ranging from the imposition of small fines to license revocation to potential incarceration. But for the citizens arrested in these five states, the ramifications of even a minor pot bust are likely to be exceptionally severe.

1. Oklahoma. Lawmakers in the Sooner State made headlines in 2011 when legislators voted 119 to 20 in favor of House Bill 1798, which enhances the state sentencing guidelines for hash manufacturing to a minimum of two years in jail and a maximum penalty of life in prison. (It took effect on November 1, 2011.) But longtime Oklahoma observers were hardly surprised at lawmakers’ latest "life for pot" plan. After all, state law already allows judges to hand out life sentences for those convicted of cannabis cultivation or for the sale of a single dime-bag.

Patricia Marilyn Spottedcrow, 25, learned the truth about Oklahoma’s excessive pot penalties the hard way when a judge sentenced the mother of four to 12 years in prison for her role in the sale of $39 worth of herb to an undercover informant. Spottedcrow’s sentence sparked national media attention – and public outrage – but neither result has led the judge in the case to reconsider the terms of her confinement.

Similarly harsh sentences for pot are par for the course in the Sooner State. Paraplegic Jimmy Montgomery was sentenced to life in prison – later reduced to 10 years – after being caught with two ounces of medical pot in his wheelchair. After considerable public outcry, Montgomery was eventually granted early release on medical parole – though he later lost a leg from an ulcerated bed sore he developed while in prison. Rheumatoid arthritis patient Will Foster – convicted of marijuana cultivation in 1997 – received a similarly draconian 93-year sentence, later reduced to 20 years on appeal. Foster was eventually paroled and moved to California, where he quickly registered as a legal medi-pot patient. However, in 2009 he was extradited back to Oklahoma to serve additional time behind bars.

Overall, some 13,000 Oklahomans are busted for pot annually. Only 12 other states arrest a greater percentage of their population for weed, and arguably no state sentences those convicted more harshly.

2. Texas. On an annual basis, no state arrests and criminally prosecutes more of its citizens for pot than does Texas. Marijuana arrests comprise over half of all annual arrests in the Lone Star State. It is easy to see why. In 2009, more than 97 percent of all Texas marijuana arrests — over 77,000 people — were for possession only. Those convicted face up to 180 days in jail and a $2,000 fine, even upon a first conviction.

Despite Texas’ dubious distinction as the #1 pot prosecuting state in America, police and lawmakers have little interest in exploring alternatives. In 2007, Gov. Rick Perry signed legislation (HB 2391) into law granting police the option of issuing a summons in lieu of an arrest in minor marijuana possession cases. Yet aside from police in Austin, long considered to be the state’s lone bastion of liberalism, law enforcement have continued to fervently make arrests in even the most trivial of pot cases.

In 2011, Houston Democrat Harold Dutton introduced House Bill 458, which sought to reduce penalties for the adult possession of one ounce or less of marijuana to a Class C misdemeanor, punishable by a fine not exceeding $500 and no criminal record. Within weeks, over 2,500 Texans contacted their House members in support of the measure. Nonetheless, House lawmakers refused to even consider bringing the measure to a vote.

3. Florida. According to a 2009 state-by-state analysis by researcher and former NORML director Jon Gettman, no other state routinely punishes minor marijuana more severely than does the Sunshine State. Under Florida law, marijuana possession of 20 grams or less (about two-thirds of an ounce) is a criminal misdemeanor punishable by up to one-year imprisonment and a $1,000 fine. Marijuana possession over 20 grams, as well as the cultivation of even a single pot plant, are defined by law as felony offenses – punishable by up to five years in prison and a $5,000 fine. In recent years, state lawmakers have revisited the state’s marijuana penalties – in each case electing to enhance Florida’s already toughest-in-the-nation criminal punishments.

Ironically, despite the Sunshine State’s long history as one of the nation’s stiffest pot prosecutors, law enforcement have steadfastly refused to report their annual marijuana arrest data to the Federal Bureau of Investigation. Illinois is the only other state that elects to withhold this information from federal statisticians.

4. Louisiana. Back in 2011, the Associated Press reported on the case of Cornell Hood II, who received a life sentence for possessing two pounds of pot. Hood received the maximum sentence under Louisiana’s habitual drug offender law because he had three prior marijuana convictions, although none of them were significant enough to result in even a single day of jail time.

Multi-decade sentences for repeat pot offenders are hardly a rare occurrence. Under Louisiana law, a second pot possession conviction is classified as a felony offense, punishable by up to five years in prison. Three-time offenders face up to 20 years in prison. According to a 2008 expose published in New Orleans City Business online, district attorneys are not hesitant to “target small-time marijuana users, sometimes caught with less than a gram of pot, and threaten them with lengthy prison sentences.”

Each year, cops make nearly 19,000 pot busts in the Bayou State – some 91 percent for simple possession – and according to Gettman, only three other states routinely punish minor offenders so severely.

5. Arizona. Forty years ago virtually every state in the nation defined marijuana possession as a felony offense. Today, only one state, Arizona, treats first-time pot possession in such an archaic and punitive manner.

Under Arizona law, even minor marijuana possession offenses may be prosecuted as felony crimes, punishable by up to 18 months in jail and a $150,000 fine. According to Jon Gettman’s 2009 analysis only Florida consistently treats minor marijuana possession cases more severely.

Annually, some 22,000 Arizonans are busted for pot and 92 percent of those arrested are charged with possession only. Citing the rising costs of these prosecutions at a time of shrinking state budgets, first-term GOP House lawmaker John Fillmore (Apache Junction) recently introduced legislation, HB 2228, to reduce pot possession to a non-criminal petty offense, punishable by no more than a $100 fine. So how did his supposedly "small government, no nanny state" colleagues respond to his proposal? With “a lot of smiles and laughs,” Fillmore told the Phoenix New Times. Predictably, HB 2228 failed to even receive a legislative hearing from his fellow lawmakers.
