Overview
- Marijuana ("pot") intoxication is the euphoria, relaxation, and sometimes undesirable side effects that can occur when people use marijuana.
- Marijuana is the most commonly used illegal drug in the United States. The drug is usually smoked, but is sometimes eaten.
- Today, there are more than 12 million marijuana users in the United States and more than 300 million regular users worldwide.
What are the symptoms of Marijuana intoxication?
- The intoxicating effects of marijuana include relaxation, sleepiness, and mild euphoria (getting high).
- Smoking marijuana leads to fast and predictable signs and symptoms. Eating marijuana can cause slower, and sometimes less predictable effects.
- Marijuana can cause undesirable side effects, which increase with higher doses. These side effects include:
- Decreased short-term memory
- Dry mouth
- Impaired perception and motor skills
- Red eyes
- More serious side effects include panic, paranoia, or acute psychosis, which may be more common with new users or in those who already have a psychiatric disease.
- The amount and effect of these side effects varies from person to person, as well as with the amount of marijuana used.
- Marijuana is often cut with hallucinogens and other, more dangerous drugs that have more serious side effects than marijuana. These side effects may include:
- Acute high blood pressure with headache
- Chest pain and heart rhythm disturbances
- Extreme hyperactivity and physical violence
- Heart attack
- Seizures
- Stroke
- Sudden collapse (cardiac arrest)
When to seek urgent medical care?
- If someone who has been using marijuana develops any of the symptoms of intoxication, has trouble breathing, or cannot be awakened, call 911 or your local emergency number.
- If the person has stopped breathing or has no pulse, begin CPR and continue it until help arrives.
Treatment options
- Caring for people with marijuana intoxication focuses on preventing injury and reassuring those who have panic reactions.
- Someone who is very agitated can be sedated with benzodiazepines (such as diazepam [Valium] or lorazepam [Ativan]).
- Children who have more serious symptoms may need to be admitted to the hospital for treatment.
- People with more serious side effects may need to be hospitalized, have heart or brain monitoring, and take medication.
