Such concurrent smoking may that meets all of produce adverse behavioral and medical problems, and is associated the criteria for drug with greater levels of substance use disorder. dependence. CBehavioral studies indicate that the act of cigarette smoking serves as a cue for drug and alcohol craving, and the active ingredient of cigarettes, nicotine, serves as a primer for drug and alcohol abuse (Sees and Clarke, 1993; Reid et al., 1998). More critically, longitudinal studies have found tobacco use to be the number one cause of preventable death in the United States, and also the single highest contributor to mortality in patients treated for alcoholism (Hurt et al., 1996). Nicotine is a highly addictive substance that meets all of the criteria for drug dependence, and cigarette smoking is an especially effective method for the delivery of nicotine, producing peak brain levels within 15-20 seconds. This rapid drug delivery is one of a number of common properties that cigarette smok- ing shares with hazardous drug and alcohol use, such as the ability to activate the dopamine system in the reward circuitry of the brain. -

This forms a complex network, which includes several types of neurons, as well as glial cells. Despite extensive studies, a comprehensive classification of these neurons is still lacking. The complexity of ENS is magnified by a multiple control of the central nervous system, and bidirectional communication between various central nervous areas and the gut occurs. This lends substance to the complexity of the microbiota–gut–brain axis, which represents the network governing homeostasis through nervous, endocrine, immune, and metabolic pathways.

Amphetamine Sensitization Alters Hippocampal Neuronal Morphology and Memory and Learning Behaviors
Molecular Psychiatry https://doi.org/10.1038/s41380-020-0809-2 ARTICLE Amphetamine sensitization alters hippocampal neuronal morphology and memory and learning behaviors 1,2,5 1,2 1 Luis Enrique Arroyo-García ● Hiram Tendilla-Beltrán ● Rubén Antonio Vázquez-Roque ● 1 3 3 3 1 Erick Ernesto Jurado-Tapia ● Alfonso Díaz ● Patricia Aguilar-Alonso ● Eduardo Brambila ● Eduardo Monjaraz ● 2 4 1 Fidel De La Cruz ● Antonio Rodríguez-Moreno ● Gonzalo Flores Received: 12 November 2019 / Revised: 29 May 2020 / Accepted: 3 June 2020 © The Author(s), under exclusive licence to Springer Nature Limited 2020 Abstract It is known that continuous abuse of amphetamine (AMPH) results in alterations in neuronal structure and cognitive behaviors related to the reward system. However, the impact of AMPH abuse on the hippocampus remains unknown. The aim of this study was to determine the damage caused by AMPH in the hippocampus in an addiction model. We reproduced the AMPH sensitization model proposed by Robinson et al. in 1997 and performed the novel object recognition test (NORt) to evaluate learning and memory behaviors. After the NORt, we performed Golgi–Cox staining, a 1234567890();,: 1234567890();,: stereological cell count, immunohistochemistry to determine the presence of GFAP, CASP3, and MT-III, and evaluated oxidative stress in the hippocampus. We found that AMPH treatment generates impairment in short- and long-term memories and a decrease in neuronal density in the CA1 region of the hippocampus. The morphological test showed an increase in the total dendritic length, but a decrease in the number of mature spines in the CA1 region. GFAP labeling increased in the CA1 region and MT-III increased in the CA1 and CA3 regions. -
Concurrent Alcohol and Tobacco Dependence
Concurrent Alcohol and Tobacco Dependence Mechanisms and Treatment David J. Drobes, Ph.D. People who drink alcohol often also smoke and vice versa. Several mechanisms may contribute to concurrent alcohol and tobacco use. These mechanisms include genes that are involved in regulating certain brain chemical systems; neurobiological mechanisms, such as cross-tolerance and cross-sensitization to both drugs; conditioning mechanisms, in which cravings for alcohol or nicotine are elicited by certain environmental cues; and psychosocial factors (e.g., personality characteristics and coexisting psychiatric disorders). Treatment outcomes for patients addicted to both alcohol and nicotine are generally worse than for people addicted to only one drug, and many treatment providers do not promote smoking cessation during alcoholism treatment. Recent findings suggest, however, that concurrent treatment for both addictions may improve treatment outcomes.

References Page 1 Medications to Treat Opioid Use Disorder Research Report Discusses effective medications used to treat opioid use disorders: methadone, buprenorphine, and naltrexone. Overview An estimated 1.4 million people in the United States had a substance use disorder related to prescription opioids in 2019.1 However, only a fraction of people with prescription opioid use disorders receive tailored treatment (22 percent in 2019).1 Overdose deaths involving prescription opioids more than quadrupled from 1999 through 2016 followed by significant declines reported in both 2018 and 2019.2,3 Besides overdose, consequences of the opioid crisis include a rising incidence of infants born dependent on opioids because their mothers used these substances during pregnancy4,5 and increased spread of infectious diseases, including HIV and hepatitis C (HCV), as was seen in 2015 in southern Indiana.6 Effective prevention and treatment strategies exist for opioid misuse and use disorder but are highly underutilized across the United States. -

Nicotine and Neurotransmitters
Module 2 —Legal Doesn’t Mean Harmless Overview Overview Summary This module focuses on how two drugs, nicotine and alcohol, change the functioning of the brain and body. Both drugs are widely used in the community, and for adults, using them is legal. Nonetheless, both alcohol and nicotine can have a strong impact on the functioning of the brain. Each can cause a number of negative effects on the body and brain, ranging from mild symptoms to addiction. The goal of this module is to help students understand that, although nicotine and alcohol are legal for adults, they are not harmless substances. Students will learn about how nicotine and alcohol change or disrupt the process of neurotransmission. Students will explore information on the short- and long- term effects of these two drugs, and also learn why these drugs are illegal for children and teens. Through the media, students are exposed to a great deal of information about alcohol and tobacco, much of which is misleading or scientifically inaccurate. This module will provide information on what researchers have learned about how nicotine and alcohol change the brain, and the resulting implications for safety and health. Learning Objectives At the end of this module: • Students can explain how nicotine disrupts neurotransmission. • Students can explain how alcohol use may harm the brain and the body. • Students understand how alcohol can intensify the effect of other drugs. • Students can define addiction and understand its basis in the brain. • Students draw conclusions about why our society regulates the use of nicotine and alcohol for young people. -

The psychostimulant MPH is therapeutically used in the treatment of ADHD, but has been implicated in many pharmacological actions related to drug addiction and is considered to have abuse potential. Past work in our lab and others have shown substantial sex-differences in the neuropharmacological profile of MPH. Here a discussion of the relevant mechanisms of action of MPH and its relationship to neurotrophins and CPP are reviewed.
