まとめ

大麻の使用は人生の各段階において脳の健康に異なる影響を及ぼします最近の傾向は,高齢者の使用の増加とリスク認識の低下を示し,更新された公衆衛生戦略の必要性を強調しています.

科学分野:

神経科学
公衆衛生
精神科

背景:

大麻の使用とデルタ9テトラヒドロカンナビノール (THC) の効果は個別に異なります.
脳と行動の健康に生涯に渡る影響を理解することは極めて重要です

研究の目的:

大麻とTHCの効果を産前,青春期,成人後期にわたって検討する.
薬物使用と健康に関する国家調査 (NSDUH) のデータ (2002-2023) を用いて,大麻使用とリスク認識の動向を分析する.

主な方法:

臨床前試験と臨床試験のナラティブレビュー
過去30日間の大麻使用とリスク認識に関するNSDUHのデータ分析
2020年以降のNSDUHデータ収集の方法論的変化の検討

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

324

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...

An Overview of Psychoactive Drugs

294

Psychoactive drugs impact brain function, influencing perception, mood, consciousness, cognition, and behavior. These substances are grouped based on their effects and the mechanisms by which they act.
Stimulants such as cocaine, amphetamines, and nicotine enhance brain activity, leading to increased alertness, attention, and energy. These drugs typically raise heart rate, blood pressure, and body temperature. While they can induce feelings of euphoria, their misuse can result in severe health...

Hallucinogens and Psychedelics

282

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...

Aging

179

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Drug Abuse and Addiction: Pharmacological Phenomena

655

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...

The Effect of Aging on Tissues

2.4K

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
