6 Worst Substances for Your Brain

It is no secret that drugs and alcohol can be very damaging to the human body and brain. However, you may not know what substances can do the most damage. In fact, even some over the counter medications can be damaging to the brain when taken excessively. Here are the 6 worst substances for your brain. 



It is common knowledge that drinking alcohol heavily can cause some short term mental effects like memory loss. However, abusing alcohol can also have some long term effects on the brain as well. These effects include difficulty with concentrating, memory loss, and a condition called Wernicke-Korsakoff syndrome. Symptoms of Wernicke-Korsakoff syndrome include violent behavior or combativeness and general mental confusion. 



Like many of the other drugs on this list, cocaine alters the number of vital hormones and neurotransmitters in the brain. This can cause long term and serious issues with mental health. These mental health problems could include things such as anxiety, depression, memory loss, and a newfound difficulty concentrating. 



Heroin has huge effects on the brain’s chemistry when taken repeatedly over time. These effects alter the amount of certain vital hormones and neurotransmitters that regulate mood. Changes in the amount of these chemicals in the brain can cause long-lasting mental health problems. In addition to this, heroin can even negatively impact an individual’s ability to make decisions and control their behavior. This can heighten drug dependency, so heroin users are much more likely to require drug rehab treatment to successfully overcome their addiction. 



Methamphetamine is known to give drug addicts many long term psychological side effects. These can include things like paranoia, hallucinations, memory loss, and even aggressive or violent behavior. Unfortunately, meth can also cause new long term mental health conditions that will need to be treated even after drug detox. “Depending on the long-term effects of methamphetamine a client may have, we recommend a 90-day stay at a rehab center or at the very least an eight-week outpatient program”, says Mat Gorman, CEO at Austin Detox Center.


Prescription Drugs That Could be Damaging

Prescription drugs are completely legal when prescribed by a doctor, but that does not mean that they are not addictive or have no negative effects on the brain. It is important to talk with your doctor about prescription medications and ask what some of their negative side effects may be. Due to the fact that every prescription medication is different, asking these questions and doing your research are extremely important. 


Over the Counter Drugs That Could be Damaging

Even over-the-counter drugs can cause brain damages when taken in excess. For this reason, it is crucial that you read the labels and follow the instructions on all over-the-counter medications. The over the counter drugs that can cause negative effects on the brain include but are not limited to sleep aids or anything with a sedative effect, pain medications, antihistamines, and muscle relaxants. 



It is no secret that drugs and alcohol have a temporary effect on the brain. However, these substances can cause long-term damages to the brain as well. The 6 worst substances to the brain include alcohol, cocaine, heroin, methamphetamine, some prescription medications, and some over the counter medications when taken excessively.

I just wanted some more information on the topic in this article. And it gives me plenty of unnecessary staff. I wish I got the details on compacom.com as I used to do before. Experiments are not always good. Sometimes an old trustful resource is worth sticking to it.
