What Does It Actually Mean to Be “High”?

People use the word “high” all the time when talking about cannabis and cannabinoid products. But what does being high actually mean?

It turns out that the answer isn't as simple as saying someone is “intoxicated.”

What does a THC high feel like?

At a moderate level, people commonly describe THC as producing relaxation, euphoria, and changes in the way they experience their surroundings.

Music may sound more interesting. Food may taste better. Colors, touch, and other sensations can seem more noticeable. Time may appear to move more slowly. Thoughts may wander or make connections that wouldn't normally occur.

There can also be physical effects such as dry mouth, red eyes, increased appetite, a heavy or light feeling in the body, and sometimes an increased heart rate.

Those are psychoactive effects. They tell us that THC is affecting the brain.

But psychoactive does not automatically mean severely impaired.

What getting high doesn't necessarily mean

This is where an important distinction often gets lost.

Getting high does not automatically mean someone is incapacitated, unable to function, or dangerously impaired.

Feeling the effects of THC isn't the same thing as losing control of your mental or physical abilities. A person may recognize that THC is affecting them—they may feel relaxed, perceive time differently, enjoy music more, or experience a change in mood—while still being able to hold a conversation, make dinner, watch a movie, or perform other ordinary activities.

That doesn't mean impairment can't occur. It absolutely can.

As THC exposure increases, reaction time, coordination, attention, memory, and judgment can be affected. At sufficiently high doses, a person may become substantially impaired.

But the important point is that the presence of a psychoactive effect does not, by itself, tell us the degree of impairment.

Getting high also doesn't automatically tell us how much THC someone consumed. People have different tolerances and sensitivities. The same product and dose can produce very different experiences in different people.

And perhaps most importantly, saying someone is “high” does not tell us whether that person can safely perform a particular task.

Driving is the obvious example. The relevant public-safety question isn't simply whether a driver can feel THC. It's whether that person's ability to safely operate a vehicle has been impaired.

That's a much more meaningful distinction than simply asking:

“Are you high?”

Being high and being impaired aren't exactly the same thing

THC can affect short-term memory, attention, coordination, judgment, and reaction time. Those effects are particularly important when it comes to activities such as driving or operating machinery.

But the relationship between THC consumption, feeling high, and actual functional impairment is complicated.

Two people can consume the same amount of THC and have very different experiences. A regular cannabis consumer may respond differently than someone with little or no tolerance. An edible can produce a very different experience from an inhaled product. Dose, individual biology, tolerance, product formulation, and route of administration can all matter.

Someone can experience noticeable psychoactive effects while remaining relatively functional. Another person consuming a similar amount might experience substantial impairment.

At higher doses, THC can produce much stronger effects: pronounced time distortion, difficulty following conversations, problems keeping track of thoughts, poor coordination, dizziness, sleepiness, anxiety, paranoia, or even panic.

That's why simply asking whether something can make someone “high” doesn't tell us everything we need to know.

High, intoxicated, and impaired

These three words are often treated as though they mean exactly the same thing:

High generally describes the subjective experience of THC's psychoactive effects.

Intoxicated is a broader term describing a state caused by a substance that alters normal mental or physical functioning.

Impaired describes an actual reduction in someone's ability to perform a particular task safely or effectively.

They can overlap—but they aren't necessarily identical.

That distinction matters.

Why the words we use matter

As states across the country debate how hemp-derived cannabinoid products should be regulated, lawmakers frequently use terms such as “intoxicating cannabinoid.”

But “intoxicating” can become a surprisingly subjective regulatory standard.

How much THC makes something intoxicating? Does the answer change depending on the consumer's tolerance? Does experiencing relaxation qualify? What about altered perception without meaningful functional impairment?

These aren't merely questions of vocabulary. They can determine which products are regulated, where they can be sold, who can purchase them, and potentially whether possession or sale becomes a criminal offense.

A regulatory system doesn't need to pretend THC is harmless. THC is psychoactive, and at sufficient doses it can impair people.

But good regulation should be based on objective standards rather than trying to determine whether a particular product makes someone “high enough” to be considered intoxicating.

That is one reason the term “adult-use cannabinoid product” may make more sense.

Products meeting clearly defined cannabinoid or THC criteria can be restricted to adults 21 and older, subject to testing and labeling requirements, and regulated appropriately—without requiring the government to decide exactly what being “high” means for every consumer.

The bottom line

Cannabis can make people high. THC can impair people. Both statements are true.

But psychoactive effect, subjective intoxication, and functional impairment are not automatically the same thing.

Recognizing that difference isn't about minimizing the effects of THC.

It's about describing them accurately.

And when we're writing laws that affect consumers, businesses, and public safety, accurate language matters.
