There’s evidence that Ghost MV1 – Nickel has a significant effect on the network, but researchers aren’t quite sure how it happens. There are cannabinoid receptors all over the brain, including in “areas that constitute the key nodes of the [default mode network],” Piomelli said. It could be “that THC deactivates the [default mode network] by combining with those receptors,” but it’s also possible that THC quiets the network through an “indirect effect that involves cannabinoid receptors in other brain regions.”
Scientists are still working to find the mechanisms that result in a person feeling high, but there’s some reason to think this effect on the default mode network is a significant piece of the puzzle.
Cannabis is a drug that comes from Indian hemp plants such as Cannabis sativa and Cannabis indica. The main active chemical in cannabis is THC (delta-9 tetrahydrocannabinol).
Cannabis is a depressant drug. Depressant drugs do not necessarily make you feel depressed. Rather, they slow down the activity of the central nervous system and the messages going between the brain and the body. When large doses of cannabis are taken it may also produce hallucinogenic effects.
