Introduction
Marijuana has long been a controversial topic in the United States and around the world. While many are calling for its legalization for both medical and recreational purposes, there are still questions around its long-term effects, risks, and societal costs versus its benefits. This paper will examine both sides of the debate around the legalization of marijuana in the United States. Specifically, it will explore the following research question: should marijuana be legalized for recreational and/or medical use at the federal level?
History of Marijuana Laws and Prohibition in the United States
Marijuana first became popular in the United States in the early 1900s and was used both recreationally and medically. At that time, it could be purchased over the counter as an extract or tincture. By the 1930s, marijuana began to be associated with immigrant and lower class groups and faced increased regulation and restrictions. This led to the Marihuana Tax Act of 1937 which effectively criminalized the possession and use of marijuana in the United States by imposing registration requirements and prohibitive tax rates on growers, sellers, and buyers.
During World War II, marijuana prohibition was further strengthened as fears grew around its relationship to violent and unpatriotic behavior. By the 1960s and 1970s, a counterculture emerged that embraced marijuana as a part of anti-establishment and pro-drug views. This led more states to decriminalize possession of small amounts of marijuana but it remained federally prohibited under the Controlled Substances Act of 1970.
President Nixon declared a “War on Drugs” in the early 1970s which ushered in a new era of harsh criminal penalties for drug offenses, including marijuana. Possession of any amount could lead to jail time and the Anti-Drug Abuse Act of 1988 established mandatory minimum prison sentences for possession and distribution. By the late 1980s and 1990s, efforts grew to reform drug laws and treat drug abuse as a public health issue rather than criminal justice one. This led to reduced penalties in some states but marijuana remained a Schedule I drug at the federal level.
Medical Marijuana Movement Emerges
In 1996, California became the first state to legalize medical marijuana through a ballot proposition, Proposition 215. This opened the door for other states to follow suit with their own medical marijuana laws allowing patients diagnosed with certain qualifying conditions, like cancer, AIDS, or chronic pain, access to marijuana for treatment. As of 2021, 37 states and the District of Columbia have implemented comprehensive public medical marijuana and cannabis programs.
The medical marijuana movement helped changed public perceptions of cannabis and its risks/benefits. Numerous scientific and medical studies have found that marijuana can effectively treat conditions like chronic pain, chemotherapy-induced nausea and vomiting, multiple sclerosis, epilepsy and more. It provides an alternative to dangerous and addictive pharmaceuticals for many patients. Federal prohibition and its Schedule I classification has limited critical research necessary to fully understanding its therapeutic mechanisms.
Full Legalization Emerges as a Movement
Spurred by changing public opinion in favor of medical access and treatment and frustrated by federal prohibition that countermanded state medical laws, the marijuana legalization movement grew into advocating for full legalization in the early 2010s. Colorado and Washington became the first states to legalize recreational marijuana through ballot measures in 2012. Since then, 15 more states, two territories, and Washington D.C. have legalized recreational marijuana for adults 21 and older through legislation or voter referendum. Another 16 states have decriminalized marijuana possession.
As more states have implemented regulated adult-use markets, strong tax revenues have been generated while public health emergencies like opioid addiction rates have declined in legal states. Questions still remain around impacts of legalization like increased youth access, commercialization concerns, and impacts to public safety like traffic accidents associated with drugged driving. Federally, there has been a shift towards a more hands-off approach under President Obama and President Biden but marijuana technically remains prohibited like a dangerous drug akin to heroin under federal statute.
This overview sets the stage to explore both sides of the ongoing marijuana debate regarding the risks and benefits of federal legalization. The following sections will examine key arguments and considerations.
Arguments in Favor of Federal Legalization
There are several compelling arguments in favor of legally regulating and taxing marijuana at the federal level. Supporters of federal legalization contend the following:
Federal prohibition has been a failed policy that negatively impacted individual civil liberties and wasted law enforcement resources: Over 41 million US citizens have used marijuana over the past decade despite its prohibition. According to the ACLU, over 663,000 people were arrested for marijuana law violations in 2018 alone. The enforcement of prohibition laws has disproportionately impacted minorities and communities of color. Legalization would help end racially discriminatory enforcement practices.
Legalization would generate substantial tax revenue that could offset health and social costs: Colorado earned over $386 million in tax revenue and fees from cannabis sales since 2014 implementation. Recreational cannabis sales topped $2 billion in California in 2021 generating over $800 million in taxes. As an agricultural product, legal marijuana could generate billions of tax dollars for federal, state and local governments to fund drug treatment, education and more.
Legalization could help curb the black market and organized crime: Where marijuana is legally regulated and available, illicit markets decline as licensed businesses can undercut illegal prices. This reduces profits of criminal cartels and gangs that exploit prohibition for underground profits. Legal states have seen decreased violence and cartel activity post-legalization. Illegal cross-border smuggling from legal states still persists in some areas.
Marijuana prohibition countermands the will of voters: According to Gallup, over two-thirds of Americans now support marijuana legalization. Over one-third of the US population lives in an adult-use legal state. Prohibition violates principles of federalism and individual liberty given this public support. Congress should respect how states are democratically regulating supply and demand.
Legalization could improve product safety regulation: Licensed cannabis businesses ensure product quality control through mandatory third-party testing of THC potency and mold/contaminant screening that users do not receive in underground or trafficked markets. This boosts consumer protection by standardizing labels of what users are actually consuming.
Cannabis can be regulated like alcohol and represents a safer alternative to opioids for certain uses: Marijuana poses far less risks of acute death/overdose than opioids. Legalization could help divert those dependent on painkillers to a safer alternative. Modeling cannabis laws after successful systems regulating alcohol distribution makes sense. Adults should have the freedom to choose between legal substances based on personal preferences.
Cannabis may have legitimate therapeutic benefits not being fully realized due to prohibition: High-quality research to fully map the human endocannabinoid system and cannabis’ direct mechanisms of action on organ systems is greatly hindered by Schedule I classification. Legalization could expedite medical research to identify potential uses in treatment of conditions like cancer, epilepsy, and chronic pain if conducted safely in regulated settings without criminal implications.
Arguments Against Federal Legalization
While support for legalization is growing, some valid concerns exist that should be addressed through responsible regulation and public policy reforms:
Legalization could exacerbate youth consumption which could impact developing brains: While youth cannabis use has actually declined in some adult-use states since legalization, like Colorado and Washington, legal access risks “normalizing” drug use at a formative age. Strict regulations would be needed to robustly limit youth commerce and marketing. Prohibition impacts youths as well through criminal records as consumption rates are tied to availability.
Legalization could worsen risks of addiction or dependency: Although less dependencies can develop from marijuana than alcohol and opioids, cannabis use disorder (CUD) is a real diagnosis impairing around 1 in 10 users. Rates of emergency room visits for CUD increased in adult-use states post-legalization though more research is needed to prove causality. Regulations must educate consumers on risks and responsible use.
Legalization could lead to an increase in drugged driving crashes: Studies indicate legalization is correlated with a slight increase in traffic fatalities in some areas from drug-impaired drivers, as roadside testing for marijuana impairment lags behind alcohol tests. Legal states are scrambling for reasonable drugged-driving laws while science progresses. Social costs must consider preventable deaths.
Legalization could expand commercialization and marketing of a regulated substance: Widespread marketing raises risks of encouraging more problematic use or youth connection to cannabis culture. Regulations are needed to limit enticements in branding and promotion aimed at vulnerable groups. Plain packaging akin to tobacco may help decommercialize promotion.
Legalization may not curb black markets and trafficking as much as expected: Legal businesses could still face price competition from tax-free illicit suppliers thus incentives persist for underground trafficking into prohibition states or across borders. Stringent tracking may be required to verify supplies are not diverted unlawfully.
Employers may struggle with workers under the influence and establishing clear impairment standards: Inhaled marijuana can linger in users’ systems detectable by urine and blood tests for weeks, long after psychotropic effects pass so proving acute impairment lags behind science. Legal ambiguity impacts workplace drug testing/policies that ensure workplace safety.
Health authorities lack long-term evidence on effects from chronic heavy use: While occasional consumption poses few serious risks for healthy adults, regular heavy use may correlate with psychotic disorders in vulnerable people or increase risks of respiratory issues over decades of cumulative use. Longitudinal health studies are still limited despite legalization in some jurisdictions.
