Takeaway

Cannabis can produce a range of effects that vary from person to person, which makes it difficult to classify it as a single type of drug.

What are the main drug types?

Drugs are categorized based on their effects and properties. Each one generally falls into one of four categories:

Depressants: These are drugs that slow down your brain function. Examples include alcohol, alprazolam (Xanax), and barbiturates.
Stimulants: These drugs elevate your mood and increase your alertness and energy. They’re usually highly addictive and can cause paranoia over time. Examples include cocaine, methamphetamine, and prescription medications for ADHD.
Hallucinogens: This type of drug alters your perception of reality by changing the way the nerve cells in your brain communicate with each other. Examples include LSD, psilocybin, and MDMA.
Opiates: These are powerful painkillers that quickly produce feelings of euphoria. They’re highly addictive and can have lasting effects on your brain. Examples include heroin, morphine, and other prescription painkillers.

So, where does weed, otherwise known as cannabis, fall among these categories? The answer isn’t as tidy as you might think. Its effects can vary widely from person to person. In addition, distinct strains and types of weed can produce different effects.

As a result, weed can be classified as a depressant, stimulant, or hallucinogen, according to the University of Maryland. However, it’s never classified as an opiate.

Keep reading to learn more about what makes weed a depressant, stimulant, and hallucinogen.

Weed as a depressant

Depressants affect your nervous system and slow brain function. Together, these actions can help to calm nerves and relax tense muscles. Depressants can help to treat several conditions, including insomnia, anxiety, or muscle spasms.

However, depressants can also have negative short-term effects, such as:

nausea
confusion
reduced motor coordination
low blood pressure
slowed breathing
slurred speech
lightheadedness
blurred vision
short-term memory loss
dizziness

Weed produces similar positive and negative effects, including:

relaxation
sleepiness
muscle relaxation
short-term memory loss
dizziness

While depressants are generally less addictive than other types of drugs, some of them, like barbiturates, carry a much higher risk. Over time, you can also develop a tolerance to depressants, including weed, meaning you need to use more of it to feel the effects that you used to feel.

You can also become dependent on weed for certain things. For example, if you use weed to help you sleep, you may eventually have trouble falling asleep without it.

In addition, smoking anything, whether it’s tobacco or weed, irritates your airways and can increase your risk of respiratory conditions, such as bronchitis or a chronic cough. Learn more about the effects of weed on your body.

Weed as a stimulant

Stimulants have the opposite effects that depressants do. They often increase your heart rate and blood pressure, causing rapid breathing in some people. Stimulants can also improve your mood, especially right after you take them.

While depressants often make you feel sleepy or relaxed, stimulants make you feel alert and energetic. They can also help to increase your attention span.

Stimulants can also have negative, and sometimes dangerous, effects, including:

increased body temperature
paranoia
irregular heart beat
anxiety
seizures
heart failure

Weed is sometimes treated as a stimulant because it can cause:

elevated moods
racing heartbeat
anxiety
paranoia

Remember, weed affects everyone differently. Some people might feel relaxed and at ease after using it, while others might feel highly alert or anxious.

Weed carries fewer risks than many other stimulants. For example, methamphetamine and cocaine are highly addictive drugs that can have lasting effects on both your brain and body.

As a stimulant, weed carries the same risks it does as a depressant. You can eventually become dependent on it for its mood-elevating effects, and smoking it can lead to respiratory issues.

Weed as a hallucinogen

Weed is perhaps most often stereotyped for its hallucinogenic effects. While hallucinations are possible, they happen rarely and don’t occur in all users. But the symptoms of weed, such as time distortion, are also part of a hallucination.

Hallucinogens are substances that alter your perception of reality, either through changes in your sensory perception or visual or auditory hallucinations.

Keep in mind that hallucinations and paranoia, which is associated with stimulants, are different things. While hallucinations are false perceptions of objects, events, or senses, paranoia involves a false idea that’s usually accompanied by suspicion.

For example, a hallucination might make you see the person walking in front of you as an animal. Paranoia, on the other hand, might make you think the person has been following you in order to harm you.

In addition to hallucinations, hallucinogens can also cause:

altered sense of time or space
loss of control over motor skills
increased heart rate
nausea
dry mouth
detachment from self or environment

Weed can have all of these additional effects, which is why many people and organizations classify it as a hallucinogen.

Over time, using hallucinogens can lead to speech problems, memory loss, anxiety, and depression. In rare cases, people may be left with psychosis, flashbacks, or a condition called hallucinogen persisting perception disorder.

As a hallucinogen, weed doesn’t do this, but it may cause both anxiety and depression, though it can also relieve these symptoms in some people. Remember, you can also develop a tolerance to or dependence on weed, and smoking it can harm your respiratory system.

The bottom line

Weed can have a variety of psychological and physical effects that vary from person to person. It can make some people tired or relaxed and give others an energy boost and increase alertness.

It can also help to treat mental health conditions, such as anxiety and depression, in some people. In others, it can actually cause anxiety over time.

As a result, weed can be considered a depressant, stimulant, or hallucinogen.
