Smoking weed can have an impact on the REM cycle, and what you experience when you sleep.
Practicing psychopharmacologist and psychiatrist Dr. Samoon Ahmad explains in this video for Business Insider, the impact of cannabis-use on sleep. Read the full transcript below.
“Sleep has different stages. If you do an EEG of a person, there are four stages of sleep and then there is a separate sleep called REM sleep, rapid eye movement sleep. And the dreaming happens in the rapid eye movement sleep. And it’s that portion of the sleep where you sort of go into paralysis, and if you wouldn’t go into paralysis you would be acting out your dreams, you’ll be jumping around doing things.”
“People who use marijuana, they tend to suppress REM sleep, they have less REM sleep. And when they have less REM sleep you’re going to have less dreams because dreams only happen during REM sleep. So, for a long time people didn’t recognize this, but once people stop smoking suddenly there’s a rebound phenomena where people can have quite vivid dreams.”
