Summary
Phencyclidine (PCP) addiction is linked to increased intimate partner violence. PCP users showed higher rates of general and intimate partner violence compared to cannabis or polysubstance users.
Area of Science:
- Forensic Psychology
- Addiction Psychiatry
- Criminology
Background:
- The relationship between phencyclidine (PCP) use and violent behavior requires further clarification.
- Intimate partner violence (IPV) is a specific form of violent behavior with significant public health implications.
Purpose of the Study:
- To investigate the association between phencyclidine (PCP) addiction and intimate partner violence (IPV).
- To compare violence perpetration rates among PCP users, cannabis users, and polysubstance (alcohol and cannabis) users.
Main Methods:
- Utilized substance abuse evaluations from 109 PCP-abusing offenders, 81 cannabis-abusing offenders, and 97 polysubstance-abusing offenders.
- Assessed differences in referral rates, legal history, and past-year violence perpetration (general and IPV) across substance use groups.
Main Results:
- Phencyclidine (PCP) users were more likely to receive inpatient referrals and have a significant legal history compared to cannabis and polysubstance users.
- PCP users reported higher rates of past-year general violence and intimate partner violence (IPV) perpetration than both comparison groups.
- Data indicate a potentially stronger association between PCP use and violence perpetration than with cannabis use or polysubstance use.
Conclusions:
- Phencyclidine (PCP) use is associated with a greater likelihood of violence perpetration, including intimate partner violence (IPV).
- The findings suggest that PCP abuse may be a significant risk factor for intimate partner violence and general violent behavior.

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...
01:30Combined Effects of Drugs: Antagonism
The combined effects of drugs can result in various interactions, of which an important type is antagonism. Antagonism is a mechanism where one drug inhibits or counteracts the effects of another drug. Antagonism can occur through various means, including receptor binding, allosteric modulation, functional interaction, chemical reactions, and pharmacokinetic processes.
The most common type is receptor antagonism, where one drug acts as an antagonist to block the effects of another drug by...

01:27Combined Effects of Drugs: Synergism
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.

01:28Psychosis and Antipsychotic Drugs: Overview
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic symptoms in all...
01:19Pharmacovigilance
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

01:24Drug Toxicity: Risk factors
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
