“Weed” is one of the many slang terms that refer to the dried, cured flowers from any plant in the cannabis family. This herbal substance is often ground, milled, or otherwise broken up and then either rolled into cigarettes or cigars or smoked in countless different pipes. Weed is among the most commonly abused drugs in the US, only behind more socially acceptable substances such as alcohol, tobacco, and caffeine.

The most recent danger of weed has come in the form of new legislation and laws in many cities and states around the country, allowing and regulating the use of weed just like alcohol. This has made the weed more accessible and has pushed the possibility of addiction to record levels. 

It seems like retail weed stores, often called “dispensaries,” are opening on every street in every town in America. Here, the users are offered a wide variety of types of weed with different effects, flavors, and purposes. Some locations even offer food products that have been combined with weed, called “edibles,” which can be dangerous for users that have not experimented with them before.

With weed that is more dangerous and potent than ever in history, now available and as easy to get as a craft beer, the potential for weed killing the user’s brain cells has never been higher. Unfortunately, weed’s effects on the brain are still largely unknown, as studies are just now becoming easier to perform without federal interference. Still, the more people have access to it and use it regularly, the more people there are that will develop problems with the drug and let it seriously affect their mind and body.

How Does Weed Impact Your Brain Cells and Body?

With weed being illegal on a federal level, there is a significant lack of research into the effects of weed on the mind and body. Nevertheless, there are some indications that some users may experience some significant effects as a result of their weed use. However, how weed impacts the user’s mind and body will greatly depend on the user and many factors of their biology and physiology.

From birth, our bodies are designed to use and produce endogenous forms of the cannabinoid compounds found in weed. This means the human body creates cannabinoids for a range of purposes. It also means that the human brain is also designed to have cannabinoid receptors to facilitate the effective use of cannabinoids. 

Weed is unique among many drugs in that it has its own receptors in our brain and does not have to interfere with other systems in the body. This also means that when a user takes weed, it is likely to cause similar effects as when the brain interacts with the natural endocannabinoids in our bodies.

In some research, those who used weed were assigned a list of vocabulary words to memorize, as were a group of people who had not used weed. The results indicated that the non-users could recall more words on average than weed users. This particular study showed a strong correlation between the use of weed and brain function, including how the brain can receive, store, and retrieve information.

Additional research has shown that there may be a link between heavy and prolonged use of weed and performance on a difficult cognitive test. The test took slightly longer than the control group, who either did not smoke or smoked lightly or occasionally before quitting. Despite the low risk and potentially minimal effects, there are still significant restrictions on research that may help us more completely understand the effects of weed on the mind and body in both the long term and the short.

Does Weed Kill Brain Cells?

Despite research projects investigating possible links between smoking weed and permanent brain damage, there has not been any concrete, peer-reviewed evidence that smoking weed damages brain structure or function. Many indications show quite the opposite, in fact, and show a potentially neuroprotective function of some of the cannabinoids (however, this is just one component of weed. Overall, the side effects of weed can be more harmful than helpful to the individual). This isn’t to say that smoking weed is without danger, however.

Like with many substances, there is a temporary effect on brain cells; some die during consumption, but it is neither a consequential nor a permanent die-off. Nearly all of the harmful effects of weed come from the actual act of smoking. Smoking results in the combustion of the desired substance to consume the active compounds and creates several other potentially toxic compounds such as carbon monoxide, tar, and more. Inhaling these compounds, as well as incredibly hot smoke, both displaces oxygen in the blood and brain as well as kills off brain cells.

How to Get Help Before Weed Kills Your Brain Cells: Treatment Options for An Addiction

Even though weed might not permanently kill your brain cells, smoking weed can still have adverse effects on the life and health of the user. Suppose you believe you or someone you know may have a substance issue with weed. In that case, the first thing that should be done is to contact recovery professionals to begin planning the detox, withdrawal, and recovery process. 

Detox from weed and getting help before weed kills your brain cells can help keep you going through a much easier and more comfortable withdrawal process. Working with experienced treatment professionals can ensure no adverse effects during the withdrawal process. It can help mitigate any physical discomfort experienced during the acute and post-acute withdrawal stages. The treatment counselors will also help the user identify their triggers. This can equip them to recognize a situation or event that may push them to relapse and use and avoid the situation entirely.
