A Procedure to Study the Effect of Prolonged Food Restriction on Heroin Seeking in Abstinent Rats
Published on: November 11, 2013
Summary
High doses of psychoactive drugs may lead to homicides by impairing reality testing and judgment. Many such violent crimes may not occur without significant drug-induced cognitive impairment.
Area of Science:
- Forensic Psychiatry
- Neuroscience
- Criminology
Background:
- Homicides associated with psychoactive substance use present complex etiological factors.
- Understanding the neurobiological and psychological impact of drug abuse on violent behavior is crucial.
Observation:
- Reviewed 24 cases of homicide linked to substantial psychoactive drug intake.
- Observed impaired reality testing and judgment in perpetrators, often without prior violence history or premeditation.
- Noted significant life stressors preceding homicides, correlating with increased substance use.
Findings:
- Psychoactive drug intoxication frequently appears to be a primary factor in these homicides.
- Impaired reality testing and judgment are identified as key indicators linking drug effects to violent criminal behavior.
- Absence of premeditation and discernible motivation suggests drug-induced disinhibition.
Implications:
- Findings highlight the critical role of drug-induced cognitive deficits in severe criminal acts.
- Suggests a need for forensic assessments to consider drug effects on mental state in homicide investigations.
- Emphasizes the importance of addressing substance abuse as a public health and safety issue.

01:29Drugs Affecting Neurotransmitter Synthesis
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
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...
01:00Drug Toxicity: Overview
Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...
01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:30Drug toxicity: Drug–Drug Interaction
Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...
01:26Pharmaceutical Poisoning: Potential Scenarios
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...
