Summary
Consistent adolescent marijuana use significantly predicts intimate partner violence (IPV). Early intervention targeting marijuana use may help prevent IPV perpetration and victimization.
Area of Science:
- Public Health
- Adolescent Health
- Criminology
Background:
- Intimate partner violence (IPV) is a major public health issue with severe health consequences.
- Previous research indicates associations between substance use and IPV, but longitudinal data on adolescent marijuana use and IPV are limited.
Purpose of the Study:
- To examine the longitudinal association between adolescent marijuana use and intimate partner violence.
- To determine if consistent marijuana use predicts IPV victimization and/or perpetration in young adulthood.
Main Methods:
- Longitudinal survey data from 9,421 adolescents (ages 15-26) in the National Longitudinal Study of Adolescent Health (Add Health) were analyzed.
- Marijuana use was assessed annually from 1995-2008; partner violence (victimization and perpetration) was measured in 2007-2008.
- Survey multinomial regression models were employed to assess the relationship between marijuana use patterns and IPV outcomes.
Main Results:
- Consistent marijuana use during adolescence was strongly predictive of intimate partner violence (Odds Ratio = 2.08, p < .001).
- Consistent marijuana use was also significantly related to an increased risk of intimate partner violence perpetration (Odds Ratio = 1.85, p < .05).
Conclusions:
- Adolescent marijuana use, especially consistent use, is associated with intimate partner violence perpetration and/or victimization in early adulthood.
- Findings suggest that marijuana use should be a consideration in early intervention and prevention programs for intimate partner violence.

02:20Longitudinal Research
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

01:24Substance Use Disorders Affecting Sleep
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:17Drug Dependence
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...
01:26Longitudinal Studies
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
01:15Drug Abuse and Addiction: Pharmacological Phenomena
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
