Marijuana smokers don’t see dreams

///Marijuana smokers don’t see dreams

marijuana smokingMany people who smoke marijuana say that after smoking they do not see dreams at all. However, if the same people give up smoking, then they note that they see bright and intense dreams.

We see the most vivid dreams during the REM sleep stage, so that raises the question whether marijuana affects the stage of REM sleep. A study conducted in 1975 (Feinberg, I., Jones, R, Walker JM, Cavness, C, March, J. Effects of high dosage delta-9-tetrahydrocannabinol on sleep patterns in man) compared the sleep patterns of heavy marijuana smokers with those of non-smokers. The results showed that smokers have a lower speed of eye movement, and their REM sleep is very slow, which reduces the ability to see dreams.

Since marijuana tends to suppress dreams, when you withdraw it, dreams come back with a vengeance. It can be brightly colored, emotionally-rich dreams or nightmares, sometimes perceived as reality. Waking up and then falling asleep again, you find yourself in the same dream again. These vivid dreams usually occur every night about a week after the rejection of the drug and last about a month and then gradually taper off.

Thus, there is scientific evidence that marijuana smoking is closely related to one’s inability to dream, so the next time you smoke and can’t remember if you dreamed anything, you will know the answer to your question. 🙂

    I smoked cannabis everyday for several years and woke up each morning without any memory of dreaming, it was very frustrating! I found it ironic as dreams can arguably let us access the subconscious thoughts and feelings that cause dependency, allowing one the awareness to take more control of it.

    The most intense dream I had upon quitting involved me being an entity consisting of just light, pulsating and morphing with each thought. It was like learning how to ride a bike for the first time while on hallucinogens in another dimension, and it wasn’t fun. Let’s just say I didn’t wake up feeling refreshed.

    Lesson learned: if you abuse drugs they will abuse you right back.
