How alcohol and THC effects the liver compared to stimulant medications



 Moderate or daily alcohol use combined with THC in adults with ADHD can have several negative effects over time:

  • Alcohol and THC both impact brain functions like attention, memory, decision-making, and impulse control, which are already areas of challenge for people with ADHD. Drinking alcohol regularly, even moderately, can make ADHD symptoms worse by increasing impulsivity, restlessness, and difficulty focusing. Long-term alcohol use also raises the risk of developing alcohol use disorder, which is more common in people with ADHD.
  • THC (cannabis) can further impair working memory, attention, and executive function, particularly with chronic use. For someone with ADHD, whose brain is already vulnerable in these areas, THC can amplify difficulties with decision-making and risk-taking behaviors. There is also a higher chance of developing cannabis use disorder.
  • Combining alcohol and THC can cause additive effects, making cognitive and emotional regulation even more challenging. It can also interfere with the effectiveness of ADHD medications.
  • Adults with ADHD who use alcohol and THC daily are at increased risk for worsened mental health symptoms such as anxiety, depression, and unstable emotions, along with worsened cognitive decline over time.

Overall, for adults with ADHD, moderate or daily alcohol use combined with THC is likely to accelerate cognitive difficulties, worsen ADHD symptoms, increase substance use disorder risk, and negatively affect emotional health compared to abstaining or controlled use of ADHD medications alone.gatewayfoundation+4

Here are the most common signs of ADHD in adults aged 40 and up:

  • Difficulty paying attention and staying focused on tasks, often getting easily distracted or missing details.
  • Problems with organization and time management, such as forgetting appointments or struggling to prioritize tasks.
  • Restlessness or feeling internally "on the go," sometimes expressed as fidgeting or an inability to sit still.
  • Impulsiveness, like interrupting others, making hasty decisions, or having difficulty controlling emotions.
  • Trouble finishing tasks, leading to incomplete projects or missed deadlines.
  • Mood swings, low frustration tolerance, and difficulty coping with stress.
  • Forgetfulness and frequently losing things like keys or phones.
  • Challenges in relationships due to inattentiveness, impulsiveness, or appearing insensitive.
  • Feeling overwhelmed or underachieving, often accompanied by low self-esteem.

In adulthood, hyperactivity often lessens compared to childhood but restlessness and impulsivity may persist. Symptoms need to cause ongoing difficulties in daily life across multiple settings (work, home, relationships) to be diagnosed as ADHD.

These symptoms can feel more intense or change with age, and for some adults symptoms may have been missed or undiagnosed until later in life. ADHD in adults often coexists with anxiety, depression, or other mental health conditions.mayoclinic+3

Yes, someone who drinks alcohol regularly for 40 years—even if only moderately—and also uses THC gummies could experience faster cognitive decline, especially if they have a family history of ADHD.

Long-term alcohol use is well-known to damage the brain. Even moderate drinking over decades can cause brain shrinkage and impair memory, attention, and other cognitive functions. THC (the active part of cannabis gummies) can further affect brain areas responsible for memory and attention, particularly if used heavily or for many years. When alcohol and THC are used together regularly, the negative effects on brain function can be stronger.

For someone with ADHD or a family history of it, brain differences related to attention and memory may already exist, making the brain more vulnerable to damage from substances like alcohol and THC. This combined use over a long time increases the risk of worsening cognitive decline, including problems with learning, memory, and focus.jamanetwork+3

Here’s an explanation suited for a high school student:

For someone with ADHD, using stimulant medicine like Adderall or methylphenidate is generally safe for the liver when taken correctly as prescribed. These stimulants are processed in the liver, and in rare cases, especially with misuse or overdose, they can cause liver injury or raise liver enzyme levels, but this is uncommon with proper use. Some nonstimulant ADHD medications, like atomoxetine (Strattera), have a slightly higher risk of causing liver problems, and doctors usually monitor liver function when people take them.

On the other hand, drinking alcohol every day, especially when combined with THC gummies, is much harder on the liver. Alcohol is directly toxic to the liver and can cause inflammation, scarring (cirrhosis), and serious long-term damage. THC alone doesn’t usually harm the liver much, but mixing it with alcohol can make the effects worse and put more strain on your body.

In summary, while ADHD stimulant medications could cause liver problems if misused or taken in very high doses, drinking alcohol daily with THC is generally far more damaging to the liver over time. The liver can usually handle ADHD medicines if used properly, but alcohol combined with THC is more likely to seriously hurt your liver long term.emedicinehealth+4

Here is a simple way to explain it to an elementary student:

Drinking alcohol every day and taking THC gummies can hurt your liver a lot over time because alcohol is like a strong poison for the liver. The liver is like a filter in your body that cleans bad stuff out, but if you drink alcohol a lot, the liver gets tired and sick. THC gummies by themselves don’t hurt as much, but mixing them with alcohol can make the liver even more tired.

Taking medicine called stimulants (used for ADHD) can also make the liver work hard, but if you take the medicine the right way, it usually doesn’t hurt the liver too much. The problems usually happen if someone takes too much medicine or mixes it with alcohol.

So, drinking alcohol every day with THC is usually harder on your liver than taking the medicine correctly. The liver can get very sick from drinking too much alcohol, but it can usually handle the medicine if used the right way.

In short: Drinking alcohol a lot hurts the liver more than taking your ADHD medicine the right way.lakeviewhealth+2

For someone with ADHD, comparing the long-term liver effects of drinking alcohol daily combined with THC gummies versus using stimulant medications presents distinct risks:

  • Daily alcohol consumption, especially combined with THC, is more likely to cause significant liver damage over time. Alcohol is directly hepatotoxic—it depresses the central nervous system and chronically damages liver cells, potentially leading to inflammation, cirrhosis, and liver failure. Chronic alcohol use also worsens ADHD symptoms, disrupts sleep, and may increase risks of addiction, compounded by THC's cognitive impairments and risks of dependence. THC alone's impact on liver is less directly toxic but combined use with alcohol can amplify health risks, including cardiovascular strain and worsened mental symptoms.calm+1
  • Stimulant ADHD medications like Adderall (amphetamine) are metabolized in the liver and can cause liver enzyme elevation, oxidative stress, and hepatocyte damage if misused or taken in high doses. Chronic misuse can lead to acute liver injury, inflammation, and in severe cases, liver toxicity and failure. However, prescribed and medically supervised use usually poses minimal liver risk. Liver damage from stimulants is often related to overdose or combined use with other substances (such as alcohol).tidesedgedetoxcenter+3

In summary, daily drinking combined with THC gummies is generally harder on the liver long-term than medically supervised stimulant use for ADHD**.** Alcohol’s direct hepatotoxic effects and synergy with THC produce greater cumulative liver damage risk. Stimulants can affect the liver mainly under misuse or high chronic doses. Both carry some risk, but regular alcohol use with THC is more detrimental to liver health in the long term for someone with ADHD.lakeviewhealth+3

Here’s a high school level explanation of the liver’s role in dopamine and the brain:

Dopamine is a chemical in the brain that helps control things like movement, motivation, and how we feel pleasure or reward. It is mainly made in the brain and cannot directly come from other parts of the body because dopamine itself cannot cross the barrier that separates the bloodstream from the brain.

The liver doesn’t make the dopamine used in the brain, but it plays an important supporting role. The liver helps break down substances in the body and keep things balanced—including chemicals that the body uses to make dopamine. Your gut and its bacteria actually produce some dopamine, which affects liver health and immune responses, but this dopamine stays mostly outside the brain.

When the liver is healthy, it helps maintain a good balance of chemistry and supports overall body health, which indirectly supports normal brain function including dopamine signaling. If the liver is not working properly, it can cause inflammation and other problems that might affect how dopamine works in the brain. So the liver’s health is important for keeping your brain and dopamine systems working well, even though it’s not making dopamine for the brain itself.

In short, the liver supports the body’s chemical balance and immune system, which helps the brain’s dopamine system work properly, but dopamine itself is produced mostly in the brain, not in the liver.pmc.ncbi.nlm.nih+2

I learned about this in high school health class at the new gym and Coach Chenowith was my teacher for that Health class and I learned about how important liver health is in the production of dopamine in the brain.  It says it does not directly create dopamine but plays a very crucial role in signaling the brain to produce dopamine to put it simply. 
   I was in the 8th or 9th grade when I took health class which was a long time ago and I simply added the names and grades to once again prove how good my memory is because these things can be verified by my high school transcript.  I also learned from Mrs. Cox in geometry class about making assumptions, her simple mental short-cut stands true to this day, Assuming things "makes an ASS out of U and ME".  Similar to the mental shortcut my aunt told me, "Those who point fingers or  blame others usually have 3 more fingers pointing back at them" which basically means blaming or pointing fingers is non-productive and does not solve problems at all.  All it truly is, is a form of blame-shifting. So stop pointing fingers or blaming and start solving or looking for solutions to problems because blame only leads people in circles and never solves the underlying problem to begin with.
