The Budgetary Effects of Ending Drug Prohibition
"Legalization can reduce government spending, which saves resources for other uses, and it generates tax revenue that transfers income from drug producers and consumers to public coffers."
Four-in-ten U.S. drug arrests in 2018 were for marijuana offenses – mostly
"The FBI does not publish state-by-state data on marijuana arrests, but patterns differ somewhat by region. In the West, 15% of all drug arrests were for marijuana-related offenses in 2018, compared with around half in the Northeast (53%), Midwest (50%) and South (49%). Marijuana is legal for recreational use in six of 13 Western states – Alaska, California, Colorado, Nevada, Oregon and Washington – but there were fewer marijuana
arrests in the West even before the first state-approved recreational sales in the U.S. began in Colorado and Washington in 2012.
Aggressive Crime, Alcohol and Drug Use, and Concentrated
Poverty in 24 U.S. Urban Areas
"We find for a large national sample of arrestees that testing positive for illegal drug use is
negatively associated with aggressive crime and that, in contrast, self-reported frequent use
of alcohol has strong and robust positive effects. These results are consistent with our earlier
research in Houston, Dallas, San Antonio, as well as European national-level studies of
aggressive behavior and substance use. The negative association of drug use on
aggressive crime supports the less popular notion that illegal drug-related violence has less
to do with intoxication (pharmacological) and possibly more with other factors. This confirms our hypothesis that social structural conditions of an urban environment differentially
expose persons to conditions that predict being arrested for an aggressive crime. Our findings tend to counter the cultural theorists who argue for an indigenous culture of violence in inner-city ghettos and barrios".

"We exploit the staggered legalization of recreational marijuana enacted by the adjacent states of Washington (end of 2012) and Oregon (end of 2014).Combining county-level difference-in-differences and spatial regression continuity designs, we find that the policy caused a significant reduction in rapes and property crimes on the Washington side of the border in 2013–2014 relative to the Oregon side and relative to the pre-legalization years 2010–2012. The legalization also increased consumption of marijuana and reduced consumption of other drugs and both ordinary and binge alcohol."

"However, these early reports of steep increases in (driving accients) are confounded by a number of factors. We contribute to this discussion by using a synthetic control method to compare the outcomes in Washington and Colorado to other states with similar pre-legalization economic and traffic trends. We find the synthetic control groups saw similar increases despite not legalizing marijuana. Moreover, the p-values suggest that the deviations Colorado and Washington did show from their synthetic counterparts are well with the range of deviations seen due to year to year variation."

Cannabis Significantly Reduces the Use of Prescription Opioids and Improves Quality of Life in Authorized Patients: Results of a Large Prospective Study
"This study provides an individual-level perspective of cannabis substitution for opioids and other prescription drugs, as well as associated improvement in quality of life over 6 months. The high rate of cannabis use for chronic pain and the subsequent reductions in opioid use suggest that cannabis may play a harm reduction role in the opioid overdose crisis, potentially improving the quality of life of patients and overall public health."

NC Blacks are 3.4 times more likely than whites to be arrested for marijuana possession. Counties vary from 9.6x in Hoke to 1.9x in Wake. The report finds that between 2001 and 2010, there were over 8 million marijuana arrests in the United States, 88% of which were for possession. Marijuana arrests have increased between 2001 and 2010 and now account for over half (52%) of all drug arrests in the United States, and marijuana possession arrests account for nearly half (46%) of all drug arrests. In 2010, there was one marijuana arrest every 37 seconds, and states spent combined over $3.6 billion enforcing marijuana possession laws. Money spent enforcing marijuana possession in NC = $54,934,668.
Drug Recognition Experts (DREs) are especially important in cases of marijuana-impaired drivers, because of the nature of marijuana itself. As with other drugs, marijuana impairment varies tremendously by individuals, even under the same dose. Marijuana does not break down in the body in a manner that correlates with psychoactivity of the drug (alcohol is the exception in this regard, not the norm), making chemical testing results of little use in determining impairment. In contrast, with few exceptions the signs and symptoms of marijuana ingestion that DREs evaluate will not appear when the drug is no longer psychoactive in a person's system, but can still appear in chemical testing for weeks after use. For these reasons, DREs evaluations are far more accurate in determining marijuana impairment in drivers, and police departments should make use of these highly trained officers, especially in states with legalized marijuana use.
Evidence suggests that removing harsh penalties for non-violent drug offenses, such as marijuana possession, affects employment and earnings for those most likely to be arrested.
Initially developed to detect alcohol impairment in drivers, the Standardized Field Sobriety Test (SFST) is currently being used by law enforcement to detect impairment due to drugs.
These findings provide support for the use of the SFST as a screening tool for law enforcement to identify impairment in persons who have used CNS stimulants, CNS depressants, cannabis, or narcotic analgesics.
"The central finding gleaned from the present study was that MML is not predictive of higher crime rates and may be related to reductions in rates of homicide and assault. Interestingly, robbery and burglary rates were unaffected by medicinal marijuana legislation, which runs counter to the claim that dispensaries and grow houses lead to an increase in victimization due to the opportunity structures linked to the amount of drugs and cash that are present. Although, this is in line with prior research suggesting that medical marijuana dispensaries may actually reduce crime in the immediate vicinity."
Does Legalizing Marijuana Reduce Crime?: Reason Foundation - September, 2018
The evidence presented suggests that legalization of marijuana for medical or recreational use results in: Patients substituting marijuana for other drugs, including opiates. Marijuana consumers substituting legal marijuana for illicit marijuana. A significant reduction in crimes associated with marijuana production, distribution, sale and possession. Reductions in other crimes, including some property and violent crimes. These effects vary by location, with reductions in property and violent crimes being most pronounced in locations close to the Mexican border due to the diminution of activities of Mexican drug trafficking organizations and affiliated gangs.
These impaired driving courses have been approved by NHTSA and IACP. International Standards have been established by IACP to ensure consistency in the content, delivery, and application of the SFST and drugged driving detection training. The SFST Standards are provided in this Administrator Guide.
States should develop record systems that distinguish among alcohol, drugs, or both for impaired driving cases. These records should be integrated into computerized data systems of statewide arrest records, the court record systems, and motor vehicle records. One way to accomplish this would be to have separate offenses for driving impaired by alcohol and driving impaired by drugs.
"In both the U.S. and Canadian studies, it is important to keep in mind that a positive drug test does not necessarily indicate “impairment.” The level of drugs detected may have been too low
to be impairing. Moreover, many drugs can be detected in oral or blood tests long after their effects have diminished. For example, marijuana can be detected for 30 days or longer among heavy users."
The introduction of medical marijuana laws (MMLs) lead to a decrease in violent crime in states that border Mexico. The reduction in crime is strongest for counties close to the border (less than 350 kilometres) and for crimes that relate to drug trafficking.
