Should marijuana be legalized? The latest Gallup poll reports that exactly half of Americans say "yes"; opinion couldn't be more evenly divided.
Marijuana is forbidden by international treaties and by national and local laws across the globe. But those laws are under challenge in several countries. In the U.S., there is no short-term prospect for changes in federal law, but sixteen states allow medical use and recent initiatives to legalize production and non-medical use garnered more than 40% support in four states. California's Proposition 19 nearly passed in 2010, and multiple states are expected to consider similar measures in the years to come.
The debate and media coverage surrounding Proposition 19 reflected profound confusion, both about the current state of the world and about the likely effects of changes in the law. In addition, not all supporters of "legalization" agree on what it is they want to legalize: Just using marijuana? Growing it? Selling it? Advertising it? If sales are to be legal, what regulations and taxes should apply? Different forms of legalization might have very different results.
Marijuana Legalization: What Everyone Needs to Know(r) will provide readers with a non-partisan primer about the topic, covering everything from the risks and benefits of using marijuana, to describing the current laws around the drug in the U.S. and abroad. The authors discuss the likely costs and benefits of legalization at the state and national levels and walk readers through the "middle ground" of policy options between prohibition and commercialized production. The authors also consider how marijuana legalization could personally impact parents, heavy users, medical users, drug traffickers, and employers.

Should marijuana be legalized? Since 2012 four US states have legalized commercial for-profit marijuana production and use, while Washington DC has legalized possession, growth and gifting of limited amounts of the plant. Other states, and even cities, have decriminalized possession, allowed for medical use, or reduced possession to a misdemeanor. While marijuana is forbidden by international treaties and by national and local laws across the globe, polls show that public support for legalization has continued to increase steadily over time. So why does the issue of marijuana legalization continue to be so controversial? One short answer is that it is an extremely complicated business, with approaches toward legalization just within the United States varying widely. What's more, not all supporters of "legalization " agree on what it is they want to legalize: Just using marijuana? Growing it? Selling it? Advertising it? If sales are to be legal, what regulations and taxes should apply? Different forms of legalization have demonstrated very different results. This second edition of Marijuana Legalization: What Everyone Needs to Know (R) provides readers with a non-partisan primer covering everything from the risks and benefits of using marijuana to what is happening with marijuana policy in the United States and abroad. The authors discuss the costs and benefits of legalization at the state and national levels and explore the "middle ground " of policy options between prohibition and commercialized production. The book also considers the personal impact of marijuana legalization on parents, heavy users, medical users, employers, and even drug traffickers.

Should we legalize marijuana? If we legalize, what in particular should be legal? Just possessing marijuana and growing your own? Selling and advertising? If selling becomes legal, who gets to sell? Corporations? Co-ops? The government? What regulations should apply? How high should taxes be? Different forms of legalization could bring very different results. This second edition of Marijuana Legalization: What Everyone Needs to Know discusses what is happening with marijuana policy, describing both the risks and the benefits of using marijuana, without taking sides in the legalization debate. The book details the potential gains and losses from legalization, explores the middle ground options between prohibition and commercialized production, and considers the likely impacts of legal marijuana on occasional users, daily users, patients, parents, and employersand even on drug traffickers.

Discussions about reducing the harms associated with drug use and antidrug policies are often politicized, infused with questionable data, and unproductive. This paper provides a nonpartisan primer on drug use and drug policy in the United States. It aims to bring those new to drug policy up to speed and provide ideas to researchers and potential research funders about how they could make strong contributions to the field.

U.S. demand for illicit drugs creates markets for Mexican drug- trafficking organizations (DTOs) and helps foster violence in Mexico. This paper examines how marijuana legalization in California might influence DTO revenues and the violence in Mexico.

Legalizing marijuana in California would lead to a major decline in the pretax price, but the price for consumers will depend heavily on taxes, the regulatory regime structure, and how taxes and regulations are enforced. The lower price and nonprice effects will increase consumption, but it is unclear by how much. There is much uncertainty about the effect on public budgets; even minor changes in assumptions lead to major differences in outcomes.
