CBC's Quirks & Quarks: Reduced REM sleep w/alcohol, cannabis, benzos, ADs

"There are a number of factors that feed into this epidemic of diminished REM sleep. And one of them includes substances, which primarily are alcohol and cannabis... So many of the most commonly used medications both prescription and over-the-counter medications can interfere with REM sleep. Examples include benzodiazepines or anti-anxiety agents antidepressants drugs that are known as anticholinergic, which are a range of medicines that affect a gastric function and also allergy. And finally sleep disorders themselves, primarily insomnia and sleep apnea, also contribute significantly diminishing REM sleep."
