Cannabis is something that’s very interesting simply because it controls the activity of the brain. Some also do believe that if you do have this for a short period of time, it can impact the short-term memory. Others also will impact impairment cognitively, along with decline. Age is a factor in this, with both adults and younger adults having differing effects on the use of THC and other memory effects. However, it can actually help with neurodegenerative conditions, including epilepsy and Alzheimer’s. CBD and the terpenes such as pinene also do mitigate a lot of the bad effects that THC creates on the short-term memory.
How it Works with the Brain
Marijuana or cannabis is used for both medical, and recreational reasons, and it’s something that has a lot of cannabinoids, flavonoids, and terpenes. This does interact with the brain in different ways, and this is something that is good, but also makes it quite troublesome for understanding the full complexity of the drug. The effects of this is definitely obvious though, at least on your endocannabinoid system.
Whenever the cannabis is put in your mouth, it goes directly into the bloodstream via the lungs or stomach, depending on how it’s consumed, and ten, it goes to the organs along with the brain. From there, it proceeds to get through the blood-brain barrier, and then, it works on both the CB1 and the CB2 receptors, and it triggers a small chemical to improve the physiological results of the consumption of cannabis. This interaction with your brain and the other effects are synergistic, and terpenes can actually control the way THC goes through towards the brain, creating an entourage effect that has different effects as well.
How it helps
The cool thing is that while it can impact memory, there are some great effects as a result of this. One of them, is the brain cell growth, otherwise known as neurogenesis, which is something that occurs within your brain as it develops, and it can actually slow down neurodegenerative conditions including Alzheimer’s. This is something that also promotes neurogenesis is in adult people, improving brain function. It actually promotes the neuron growth along those cells which have passed and offer neuroprotection. This is also something that can help reduce anxiety in people as well.

It also does well in damage recovery and reduction, especially in those who consume cannabis, especially CBD. It helps with stroke recovery, since it can reduce the damage from this. According to a study involving brain injections of CBD before a person has a stroke, it reduces the infarct, which is the damage, and thereby reduces the stroke too. It’s something that can also help after a stroke too, improving recovery.
While there isn’t much study on this, one of them did look at THC consumption, increasing the oxygen over to your prefrontal cortex, which is something that’s manipulated, reducing your infarct sizes, and also preventing the cell death of neuronal cells, and also may help with stroke recovery. Finally, it also improves the working memory. Working memory is the one that processes the task. While some people may think it doesn’t help, it actually activates your frontal lobe, improving accuracy and a better reaction time.

The people who did this research did find that the acute administration of this by smoking helped with the memory performance, working it. It’s something that also was better in those who use it. It also didn’t affect performance in those who were already above average, which helped with both encoding and learning, to provide good information too.
