If you took too much THC, get emergency help now for collapse, trouble breathing, a seizure, or if the person cannot be awakened. For a possible THC exposure that is not an immediate emergency, call Poison Control at 1-800-222-1222 for guidance; the CDC lists Poison Control and 911 as immediate resources for cannabis-related poisoning concerns. Do not take more THC, try a home antidote, or rely on a “detox” promise.
Which THC symptoms need emergency help?
Call 911 or go to emergency care for collapse, trouble breathing, seizures, or inability to wake the person. This is especially important after a child may have eaten a THC gummy. The CDC says children who consume THC-containing products can become very sick, and the FDA reports that accidental THC-product exposures have led to serious illness and hospital care.
For severe symptoms that are not clearly an emergency, including confusion, hallucinations, repeated vomiting, fainting, intense anxiety, or loss of consciousness, contact Poison Control right away and follow its instructions. The FDA lists hallucinations, vomiting, tremor, anxiety, dizziness, confusion, and loss of consciousness among reported adverse events involving delta-8 THC products.
| What is happening? | What to do now |
|---|---|
| Collapse, breathing trouble, seizure, or cannot wake up | Call 911 or seek emergency care now. |
| Possible THC exposure, including a child exposure, but no immediate emergency signs | Call Poison Control: 1-800-222-1222. Do not wait for symptoms after a child exposure. |
| Anxiety, confusion, vomiting, dizziness, or hallucinations after THC | Call Poison Control for case-specific guidance; use emergency care if symptoms become severe. |
When should you call Poison Control after THC?
Call Poison Control at 1-800-222-1222 when you think someone may have consumed too much THC, including after an edible or gummy, and especially when a child may have gotten into a product. The CDC says edibles can have delayed or unpredictable effects and can increase the risk of poisoning. Poison Control can help you decide what level of care is needed from the details of that specific exposure.
Have the package available if you can. Note the product name, the time it was taken, the amount shown on the label, and any other alcohol, medicines, or drugs involved. A clinician or poison specialist can use those details; this page cannot tell you what amount is safe for you or how long your symptoms will last.
What can too much THC feel like?
THC is the cannabis component that produces the high. NIDA says THC products can temporarily change mood, thoughts, and perception. With a large amount, a strong product, or little prior experience, people can have anxiety, fear, distrust, panic, or hallucinations. NIDA also lists altered time perception and impaired thinking, memory, and body movement among short-term effects.
Gummies deserve extra care because they are edibles. The CDC says edible products can have delayed or unpredictable effects. That is why an uncomfortable gummy experience is not a reason to take another serving while you wait.
Why can THC make you anxious or feel mentally different?
THC is intoxicating, meaning it can alter mood, thoughts, and perceptions. NIDA says anxiety, fear, panic, and hallucinations are more common when someone takes a large amount, uses a product with a high THC level, or has little experience with cannabis. The same source says individual effects can also vary with product ingredients, other drugs used, underlying health conditions, and personal biology.
THC and CBD are not interchangeable. The CDC says CBD by itself is not impairing and does not cause a high, while THC is impairing or mind-altering. A 2023 review in Neuron describes THC and CBD as compounds with different mechanisms and effects on brain function. That difference does not make CBD a home antidote for too much THC.
Are THC gummies hard on your body if used often?
THC can affect the brain and body, and how it affects you depends on factors including THC concentration, frequency of use, other substances, and whether the product is an edible, according to the CDC. NIDA says chronic, heavy, every-day or almost-every-day use is associated with cannabis use disorder. Signs can include craving, difficulty cutting down, spending substantial time using or recovering from cannabis, and continuing despite problems.
NIDA also describes cannabinoid hyperemesis syndrome as nausea, vomiting, and abdominal pain after long-term, heavy cannabis use. It can recur and often needs medical attention. This does not tell us what will happen to one person from once-weekly use, or whether THC caused a particular liver, kidney, or other health problem; those questions need an individual clinical assessment.
What about the liver, kidneys, dry mouth, sleep, and a cold?
The sources cited here do not provide a basis to compare THC with alcohol for liver effects, to say that THC gummies damage the liver or kidneys, or to say how THC affects a cold. If those are your concerns, bring the exact product label and your symptoms to a clinician rather than using a general cannabis page to make that call.
For sleep, the National Center for Complementary and Integrative Health says many studies in people with health problems have measured sleep-related outcomes, but it remains uncertain whether cannabis products acted directly on sleep or whether improved symptoms explained the change. Its discussion of sleep in people without other illnesses is also uncertain. For dry mouth, the sources cited here do not give a specific explanation.
Can you compare a gummy with a joint?
No single gummy-to-joint conversion is supported here. The CDC says cannabis effects depend on THC concentration, frequency of use, other substances, the way it is used, prior experience, and biology. A gummy label can tell you the listed milligrams per gummy or serving, while a joint is a different product form with different THC concentration and delivery. Use the site’s gummy label guide to find the amount on a package, but do not use that number as a personal dosing recommendation.
What does the label tell you about THC, THCA, and “TAC”?
Check the exact cannabinoid names rather than assuming that every hemp gummy is the same. THC is the main intoxicating cannabinoid discussed on this page. The sources cited here do not provide enough detail to explain a THC-versus-THCA or THC-versus-TAC comparison safely. Before you buy or use a product, look for the cannabinoid names and amounts on the label, then match them to the batch report using this COA guide.
Under the Agriculture Improvement Act of 2018 (the 2018 Farm Bill), hemp is defined federally as cannabis and derivatives with no more than 0.3% delta-9 THC on a dry-weight basis, as described by the FDA. As of October 8, 2026, that definition is not a promise about how a product will affect you, and product rules can also depend on state law. This is information, not legal advice. For the current federal-policy timeline, see federal hemp law.
What should you bring to a clinician or Poison Control?
Use this short checklist:
- The product package or a clear photo of its front and supplement-style facts panel.
- The amount shown per gummy and per serving, if listed.
- The approximate time of exposure and current symptoms.
- Any alcohol, medicines, or other substances involved.
- The product’s batch or lot number and its certificate of analysis, if available.
That is more useful than guessing from a product name. If the package says “hemp,” check whether it identifies THC, CBD, or something else; hemp seed oil versus CBD explains why those labels are not interchangeable.
