Does Cannabis Affect Your Memory?


Cannabis is obtained from the cannabis plant called Cannabis sativa. It flourishes naturally in the temperate and tropical regions of the world. Delta-9 tetrahydrocannabinol (THC), which is the primary ingredient in cannabis, is accountable for giving a stoned feeling.

Cannabis is used as hash oil, hashish, and marijuana. Marijuana is manufactured from dried leaves and flowers of the weed plant. Generally, marijuana is smoked or made into brownies, cookies, and other edible products. Hashish is produced from the resin plant and is usually smoked; however, it can also be added to food. Hash oil is derived from hashish and is smoked.

Cannabis can have positive as well as negative effects on your brain. It is also important to note that specific groups of people should abstain from using cannabis.

Teenagers, for instance, should not use cannabinoids. Associations have been discovered between the growing brain and the negative impact of cannabis. For the same reason, nursing moms or pregnant women are recommended not to use cannabis.

Cannabis Use Affects Memory

Spatial Memory

Spatial memory enables you to remember details in the existing environment. However, cannabis significantly affects this type of memory. According to a study published in the journal Psychopharmacology, THC can affect spatial memory in a negative way. In another study, mice who took THC experienced difficulty in finding their way out.

Long-Term Memory

Long-term memory retains information for a long period of time that ranges from a few minutes to several years.

Experts believe that cannabis may help modulate unwanted past thoughts.

Bad Memories

Cannabis also helps people forget painful and bad memories. Traumatic memories are memories of events, such as war, where a person has been placed in negative situations. As a result of these experiences, the brain commonly remembers the trauma in the form of a flashback.

Verbal Memory

Individuals who smoke weed over time experience difficulty recalling words on a list by the time they hit middle age, reported a 2016 study.

Researchers involved in the study found that long-term use of marijuana could impact verbal memory or the region of the brain that helps people remember language or words. However, marijuana use did not affect other cognitive functions, such as the ability to focus, solve problems or think quickly.

Working Memory

Working memory is essential to problem-solving, writing, thinking, calculating, reading, and language comprehension. It is imperative for storing information for a long period of time. According to one study, long term cannabis use alters working memory. The weed disturbs the working memory function and inhibits the user from accomplishing their regular tasks. Researchers at the University of Bordeaux and the University of Ottawa demonstrated that when cannabinoids bind to their receptors in the hippocampus (area of the brain that modulates memory), they weaken the connection between neurons. Cannabinoids are chemical compounds found in cannabis buds and leaves. The hippocampus is packed with cannabinoid receptors.

More Evidence

Cannabis use can sap your memory. According to a study published in the Journal of Clinical Psychiatry, participants who ditched smoking weed reported improved cognitive abilities after only one week. However, researchers do not know if the cannabis causes the problems or if individuals smoking the drug have a poor memory to start with.

Scientists involved in the research hired 88 individuals aged between 16 and 25 years who smoked the herb once a week. They incentivized two-thirds of the test subjects with money to stop smoking the drug for 30 days. The participants underwent many mental tests at the beginning of the experiment and once a week.

The participants who quit smoking cannabis performed memory tasks better in the first week and remained at that same level for the rest of the month. while subjects who carried on smoking cannabis improved their memory task scores imperceptibly over the month.
