Korttidshukommelsen er svækket kraftigt.

Jeg har også tænk over det og tror det er en blanding af de her 2 ting:

Korttidshukommelsen er svækket kraftigt.

Når man går mega skæv i seng kommer man ikke i den samme dybe søvn, hvor man drømmer.

Måske endda flere ting der spiller ind

Jeg har røget i snart 2 år fast, jeg har ikke nogle "drømme problemer" så synes det er noget fis at skrive man ikke drømmer når man ryger dagligt. Cannabis kan jo ikke ligefrem gå ind og blokere for DMT udløsningen du får når du drømmer?

Jeg tror stadig jeg drømmer, selvom jeg pt. ryger hver dag. Jeg har dog langt, langt sværere ved at genkalde drømmen.

Emne: Hvorfor drømmer man ikke når man ryger dagligt?


Strengt taget omhandler det studie effekten af THC på deprimerede, og ikke dets effekt på drømme. Det lader til at der kunne være en effekt på REM søvnen, gennem de observerede ændringer, men om det er faktoren der spiller ind mht den manglende erindring af drømme vides ikke - og belyses heller ikke af deres forskning.

Ikke at det er super relevant, måske endda lidt flueknepperi, jeg ville bare påpege at du heller ikke kunne finde et studie der omhandler THC's effekt på drømme.

Dreams mainly occur in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake. REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable.

Both drugs reduced eye movements density with some tolerance developing to this effect. Stage 4 tendend to increase with drug administration. Abrupt withdrawal led to extremely high densities of eye movement, increased rapid eye movement (REM) durations

According to one theory, certain memories are consolidated during REM sleep. Numerous studies have suggested that REM sleep is important for consolidation of procedural memory and spatial memory. (Slow-wave sleep, part of non-REM sleep, appears to be important for declarative memory.) A recent study[10] shows that artificial enhancement of the non-REM sleep improves the next-day recall of memorized pairs of words. Tucker et al. demonstrated that a daytime nap containing solely non-REM sleep enhances declarative memory but not procedural memory.[11] The role of REM sleep in memory, however, is not without its doubts. Monoamine oxidase (MAO) inhibitors and tricyclic antidepressants can suppress REM sleep, yet these drugs show no evidence of impairing memory. On the contrary, some studies show MAO inhibitors improve memory. Moreover, one case study of an individual who had little or no REM sleep due to a shrapnel injury to the brainstem did not find the individual's memory to be impaired. (For a more detailed critique on the link between sleep and memory, see Ref.[12])

jeg fik en PM fra en random dude, som ikke mente min dokumentation var tilstrækkelig, til trods for at han ikke selv har fremlagt nogen dokumentation for sine egne påstande. her er svaret

Smoked marijuana and oral Delta-9-tetrahydrocannabinol (THC) reduce REM sleep. Moreover, acute administration of cannabis appears to facilitate falling asleep and to increase Stage 4 sleep. Difficulty sleeping and strange dreams are among the most consistently reported symptoms of acute and subacute cannabis withdrawal. Longer sleep onset latency, reduced slow wave sleep and a REM rebound can be observed.
