Insights

Men using both Viagra and amphetamines together showed higher rates of HIV, hepatitis B, and syphilis. This drug combination is linked to specific sexual behaviors and other substance use among men who have sex with men.

Area of Science:

  • Public Health
  • Epidemiology
  • Substance Use Research

Background:

  • Recent studies indicate a link between Viagra and methamphetamine use and unprotected anal intercourse in men who have sex with men (MSM).
  • Previous research in Long Beach, California, identified an association between Viagra use and amphetamine use during sexual activity.

Purpose of the Study:

  • To investigate the combined use of Viagra and amphetamines in men in Long Beach, California.
  • To identify risk and protective factors associated with the co-use of Viagra and amphetamines.

Main Methods:

  • Data were collected from 1,839 men in HIV prevention and testing programs using the Risk Behavior Assessment.
  • A generalized logit model was employed to compare users of both drugs, users of one drug, and non-users.

Main Results:

  • Men using both methamphetamine and Viagra concurrently exhibited a significantly higher prevalence of hepatitis B, syphilis, and HIV compared to those using only one or neither drug.
  • 11.1% of participants reported using both amphetamine and Viagra.
  • Significant predictors of co-use included gamma-hydroxybutyrate (GHB), cocaine, ecstasy, HIV infection, White race, hepatitis B, crack cocaine, exchanging sex for money, hotel living, prior drug treatment, and heroin use. Heterosexuality was a protective factor.

Conclusions:

  • Concurrent use of Viagra and amphetamines is associated with increased prevalence of serious infectious diseases, including HIV, hepatitis B, and syphilis.
  • Specific substances like GHB and behaviors like exchanging sex for money are strongly associated with this drug co-use.
  • Viagra use correlated with insertive anal intercourse, while methamphetamine use correlated with receptive anal intercourse.

Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Stimulants01:29

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Drug 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...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its effects by...
Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
Drug Dependence01:17

Drug 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...
