Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

468
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.
Understanding the concepts of physical dependence,...

Drug Dependence01:17

Drug Dependence

1.8K
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...

Drug Abuse and Addiction: Pharmacological Phenomena

1.3K
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...

CNS Depressants: Alcohol and Nicotine

1.4K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

974
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...

Hallucinogens and Psychedelics01:27

Hallucinogens and Psychedelics

790
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains...

Summary

Recovery from cannabis use disorder often involves changes in other substance use. While decreases are more common, increases also occur, particularly in self-directed recoveries with fewer cannabis-related problems.

Area of Science:

  • Addiction research
  • Psychiatry
  • Public health

Background:

  • Understanding co-occurring substance use is crucial for addiction recovery.
  • Limited research exists on how recovery from one addiction impacts subsequent substance use patterns.

Purpose of the Study:

  • To explore self-reported changes in other substance use among individuals recovering from cannabis use disorder.
  • To identify factors associated with increased or decreased use of other substances during recovery.

Main Methods:

  • Media recruitment yielded 119 participants with past cannabis use disorder but not in the past year.
  • Data collected on changes in other substance use, cannabis-related problems, and recovery strategies.
  • Median recovery length was 5.0 years.

Main Results:

  • Both increases and decreases in other substance use are common during cannabis use disorder recovery.
  • Overall, other substance use tended to decrease more than increase.
  • Individuals reporting only decreased other substance use or both increases and decreases had more severe cannabis-related problems and treatment history.

Conclusions:

  • Treatment involvement and social influences may help reduce other substance use during cannabis recovery.
  • Self-directed recoveries, particularly those with increased other substance use, appear less socially embedded.
  • Further research is needed to clarify the impact of these substance use changes on individual functioning.
