まとめ

カナダの高齢者は大麻の使用が増加しており,その半数近くがリスクが低いと認識しています. 大麻の安全性や有効性に関する情報が不足している.

科学分野:

ゲロントロジー
公衆衛生
大麻の研究

背景:

2018年の合法化以来,カナダの高齢者 (50歳以上) の大麻使用は増加しています.
カンナビスに対する認知は限られている.

研究の目的:

カナダの高齢者の大麻使用パターンを決定する.
大麻の安全性,有効性,および汚名を特徴づける.

主な方法:

50歳以上のカナダ人に電子調査が行われました.
データには,大麻の経験,認識 (リケートスケール,オープンテキスト),人口統計的要因が含まれています.
ロジスティック回帰は知覚に影響を分析した.

主要な成果:

回答者の44%が現在の大麻使用を報告した.
半数近く (49.2%) はリスクが低いと認識し,主な懸念は認知/精神的健康 (40.8%) と身体的健康 (19.1%) であった.
安全性に関する情報は不十分だと60. 4%が感じ,有効性については63. 8%が感じ,34. 7%がステグマを感じた.

結論:

カンナビスの使用と認識には,世代と性別による大きな違いがある.
医療従事者や公衆衛生担当者は教育のニーズを満たすためにこれらの違いに対処しなければなりません
カンナビスを安全かつ情報に基づいた方法で使用するには,カスタマイズされた教育戦略が不可欠です.

Hallucinogens and Psychedelics

279

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...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

366

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

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...

Stress Prevention and Stress Management Techniques IV

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

Stimulants

311

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...
