How Can You Tell If Someone is High?

Recognizing when someone is high on substances like marijuana, or other drugs can be a challenge, especially if you’re not familiar with the signs. Knowing how to tell if someone is high is crucial if you’re concerned about a loved one’s substance use or if you’re in a position to offer help. Here are 14 common signs to look for when trying to determine whether someone may be under the influence.

1. Bloodshot or Glassy Eyes

One of the most telltale signs of someone being high is bloodshot or glassy eyes. When someone uses marijuana or other substances, the blood vessels in the eyes dilate, making the whites of their eyes appear red or irritated. This is often one of the first physical signs when figuring out how to see if someone is high.

2. Dilated or Constricted Pupils

Depending on the substance used, pupils can either be extremely dilated (larger than usual) or constricted (smaller than usual). For example, someone who is high on stimulants like cocaine may have noticeably larger pupils, while someone under the influence of opioids might have pinprick-sized pupils.

3. Unusual Odor

If you’re trying to figure out how to tell if someone is high on weed, the smell can be a major giveaway. Marijuana has a distinctive odor that lingers on clothing, hair, and breath. Even if the person has used cologne or gum to mask the smell, the scent often persists.

4. Slurred or Slow Speech

When someone is high, their speech may be noticeably altered. They might speak slower than usual, slur their words, or have difficulty forming coherent sentences. This is often the case with sedatives, alcohol, or cannabis. If you’re interacting over the phone or in person, this is a key sign of impairment.

5. Poor Coordination

Another common indicator when learning how to see if someone is high is impaired motor coordination. This may manifest as clumsiness, trouble walking straight, or difficulty with simple tasks like holding objects or opening doors.

6. Delayed Reactions

Someone under the influence of drugs might exhibit delayed reactions, responding slowly to stimuli or questions. Whether it’s slow physical reactions or mental processing, this can be a sign that their central nervous system is being affected by substances.

7. Mood Swings or Emotional Changes

Sudden mood swings can be a sign of intoxication. Some drugs cause people to become more euphoric, giddy, or over-excited, while others may make them anxious, paranoid, or irritable. For example, when learning how to tell if someone is high on weed, some people may seem overly relaxed or giggly.

8. Dry Mouth or Excessive Thirst

Many substances, including marijuana, can cause dry mouth, often referred to as “cottonmouth.” If someone is drinking large amounts of water or frequently licking their lips, it might be an indication that they are high.

9. Lack of Focus or Concentration

When someone is high, it can be difficult for them to stay focused on a task or conversation. They may drift off, lose their train of thought, or seem unable to concentrate. This lack of focus can be especially apparent during long conversations or when someone is trying to complete tasks.

10. Excessive Laughing or Talking

People under the influence of marijuana often exhibit excessive laughter or find things funnier than they typically would. If someone seems to be laughing uncontrollably at things that aren’t particularly humorous, this might be a sign that they are high.

11. Increased Appetite

Marijuana is notorious for causing “the munchies.” If someone is suddenly eating large amounts of food or snacking on unusual combinations, it could be a sign that they are high. This is one of the more specific signs when figuring out how to tell if someone is high on weed.

12. Paranoia or Anxiety

Some drugs, especially marijuana in higher doses, can lead to feelings of paranoia or heightened anxiety. If someone seems overly suspicious, nervous, or agitated without cause, they may be experiencing these drug-induced effects.

13. Short, Vague Responses Over Text

When trying to understand how to tell if someone is high over text, one of the biggest clues is how they communicate. If someone is high, their text responses might be unusually short, delayed, or vague. They might not make sense, or the person may forget parts of the conversation. Their tone could also change drastically, from upbeat to lethargic or incoherent.

14. Memory Problems

Another sign that someone may be high is difficulty remembering things. Short-term memory is often impaired, especially with marijuana use. If someone repeatedly asks the same question or forgets something that was just discussed, this could be a sign that they are under the influence.
