Silvia Saboia Martins is a Brazilian epidemiologist and the director of the Substance Use Epidemiology Unit of the Department of Epidemiology, Columbia University Mailman School of Public Health. Her research considers the epidemiology of substances abuse and origins of high opioid prescribing. She has won numerous awards for her mentoring, including the Irving Medical Center Mentor of the Year.
Martins earned her medical degree at the Federal University of Paraná. [1] She moved to the University of São Paulo for her psychiatry residency and doctoral studies, where she was awarded a São Paulo Research Foundation predoctoral fellowship. [1] She was a postdoctoral fellow at Johns Hopkins University, where she was appointed to the faculty in 2005. [2] Here she studied the prevalence of gambling among young people, and found that around 15% of African-American inner-city young people had some form of problem gambling. [3]
In 2012 Martins joined Columbia University. [4] Her research focuses on the epidemiology of substance use. She has studied the impact of medical and recreational cannabis laws in the United States. Her focus extends to exploring the combined effects of opioid and cannabis policies on mitigating opioid-related harm outcomes in the country. She also studies the trends in drug overdoses in Latin America. She has analysed the implications of opioid and substance use policies specifically designed for pregnant and postpartum women who are opioid users in the U.S. She found that during 2020 overdoses played a role in one in six pregnancy-associated deaths. [5]
She has studied the typology of prescription drug monitoring programs, and how it impacts opioid and heroin overdoses. She has developed machine learning techniques to understand high opioid prescribing.
She was elected to the board of directors of the College on Problems of Drug Dependence in 2022. [2]
Recreational drug use is the use of one or more psychoactive drugs to induce an altered state of consciousness, either for pleasure or for some other casual purpose or pastime. When a psychoactive drug enters the user's body, it induces an intoxicating effect. Generally, recreational drugs are divided into three categories: depressants, stimulants, and hallucinogens.
Harm reduction, or harm minimization, refers to a range of intentional practices and public health policies designed to lessen the negative social and/or physical consequences associated with various human behaviors, both legal and illegal. Harm reduction is used to decrease negative consequences of recreational drug use and sexual activity without requiring abstinence, recognizing that those unable or unwilling to stop can still make positive change to protect themselves and others.
A drug overdose is the ingestion or application of a drug or other substance in quantities much greater than are recommended. Typically it is used for cases when a risk to health will potentially result. An overdose may result in a toxic state or death.
Polysubstance use or poly drug use refers to the use of combined psychoactive substances. Polysubstance use may be used for entheogenic, recreational, or off-label indications, with both legal and illegal substances. In many cases one drug is used as a base or primary drug, with additional drugs to leaven or compensate for the side effects, or tolerance, of the primary drug and make the experience more enjoyable with drug synergy effects, or to supplement for primary drug when supply is low.
The drug policy in the United States is the activity of the federal government relating to the regulation of drugs. Starting in the early 1900s, the United States government began enforcing drug policies. These policies criminalized drugs such as opium, morphine, heroin, and cocaine outside of medical use. The drug policies put into place are enforced by the Food and Drug Administration and the Drug Enforcement Administration. Classification of Drugs are defined and enforced using the Controlled Substance Act, which lists different drugs into their respective substances based on its potential of abuse and potential for medical use. Four different categories of drugs are Alcohol, Cannabis, Opioids, and Stimulants.
Substance abuse prevention, also known as drug abuse prevention, is a process that attempts to prevent the onset of substance use or limit the development of problems associated with using psychoactive substances. Prevention efforts may focus on the individual or their surroundings. A concept that is known as "environmental prevention" focuses on changing community conditions or policies so that the availability of substances is reduced as well as the demand. Individual Substance Abuse Prevention, also known as drug abuse prevention involves numerous different sessions depending on the individual to help cease or reduce the use of substances. The time period to help a specific individual can vary based upon many aspects of an individual. The type of Prevention efforts should be based upon the individual's necessities which can also vary. Substance use prevention efforts typically focus on minors and young adults – especially between 12–35 years of age. Substances typically targeted by preventive efforts include alcohol, tobacco, marijuana, inhalants, coke, methamphetamine, steroids, club drugs, and opioids. Community advocacy against substance use is imperative due to the significant increase in opioid overdoses in the United States alone. It has been estimated that about one hundred and thirty individuals continue to lose their lives daily due to opioid overdoses alone.

An opioid overdose is toxicity due to excessive consumption of opioids, such as morphine, codeine, heroin, fentanyl, tramadol, and methadone. This preventable pathology can be fatal if it leads to respiratory depression, a lethal condition that can cause hypoxia from slow and shallow breathing. Other symptoms include small pupils, and unconsciousness, however its onset can depend on the method of ingestion, the dosage and individual risk factors. Although there were over 110,000 deaths in 2017 due to opioids, individuals who survived also faced adverse complications, including permanent brain damage.
Substance use disorder (SUD) is the persistent use of drugs despite substantial harm and adverse consequences as a result of their use. The National Institute of Mental Health (NIMH) states that "Substance use disorder (SUD) is a treatable mental disorder that affects a person's brain and behavior, leading to their inability to control their use of substances like legal or illegal drugs, alcohol, or medications. Symptoms can be moderate to severe, with addiction being the most severe form of SUD". Substance use disorders (SUD) are considered to be a serious mental illness that fluctuates with the age that symptoms first start appearing in an individual, the time during which it exists and the type of substance that is used. It is not uncommon for those who have SUD to also have other mental health disorders. Substance use disorders are characterized by an array of mental/emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol, caffeine, cannabis, hallucinogens, inhalants, opioids, sedatives, hypnotics or anxiolytics, stimulants, tobacco
In the United States, prescription monitoring programs (PMPs) or prescription drug monitoring programs (PDMPs) are state-run programs which collect and distribute data about the prescription and dispensation of federally controlled substances and, depending on state requirements, other potentially abusable prescription drugs. PMPs are meant to help prevent adverse drug-related events such as opioid overdoses, drug diversion, and substance abuse by decreasing the amount and/or frequency of opioid prescribing, and by identifying those patients who are obtaining prescriptions from multiple providers or those physicians overprescribing opioids.

In the United States, the opioid epidemic is an extensive, ongoing overuse of opioid medications, both from medical prescriptions and illegal sources. The epidemic began in the United States in the late 1990s, according to the Centers for Disease Control and Prevention (CDC), when opioids were increasingly prescribed for pain management, resulting in a rise in overall opioid use throughout subsequent years. The great majority of Americans who use prescription opioids do not believe that they are misusing them.
The opioid epidemic, also referred to as the opioid crisis, is the rapid increase in the overuse, misuse/abuse, and overdose deaths attributed either in part or in whole to the class of drugs called opiates/opioids since the 1990s. It includes the significant medical, social, psychological, demographic and economic consequences of the medical, non-medical, and recreational abuse of these medications.

In response to the surging opioid prescription rates by health care providers that contributed to the opioid epidemic in the United States, US states began passing legislation to stifle high-risk prescribing practices. These new laws fell primarily into one of the following four categories:
