Is Weed a Depressant or a Stimulant? It's Complicated

Weed isn't neatly a depressant or a stimulant: it can act like both, and at high doses it can even have mild hallucinogenic effects. Depending on the strain, the dose and the person, cannabis can calm you down, ease anxiety and help you sleep, or lift your mood, spark creativity and speed up your heart. Its knack for warping your sense of time and space has only fueled the debate.

So let's break down what cannabis actually does in the body and settle the question.

What is a depressant?

Drugs known as depressants have a relaxing, calming and even sedating effect. They can slow down brain function and are used to treat things like anxiety, muscle spasms, insomnia and seizures.

Among the most common depressants are benzodiazepines, often prescribed for anxiety and insomnia, among other conditions. Barbiturates and some antipsychotics also have a strong sedating effect.

Alcohol is also one of the best-known depressants, and it can cause many of the side effects typical of the category: memory loss, slower reaction time, a calming effect and slurred speech.

But if we're talking about the heavy hitters among depressants, we have to mention opioids. Opioids interact with the brain's opioid receptors and are used both in anesthesia and as prescription painkillers. Some are sold legally in pharmacies, like oxycodone or fentanyl, and they're highly addictive.

That's the big risk with depressants: alcohol, opioids and benzodiazepines are generally highly addictive, which makes it very easy to slide into misuse.

What is a stimulant?

Stimulants are drugs that boost energy and alertness, which can bring on an elevated, euphoric mood. But that effect doesn't last forever, and it can leave you with a mood crash once it wears off.

Cocaine, methamphetamine, Ritalin and the caffeine in your coffee are some of the most common stimulants. The catch is that they can be habit-forming and cause a “crash” when they wear off.

Even though drugs like Ritalin and Adderall are prescribed for attention disorders like ADD and ADHD, they carry a real risk of misuse and dependence.

What does weed do to your brain?

Now that you know what a depressant is and what a stimulant is, let's talk about what kind of drug weed is. First off, cannabis can produce some of the effects associated with depressants. That means it can feel relaxing and calming and ease pain and anxiety. Another effect of weed is that it can help you fall asleep and fight insomnia if you use it before bed. That's why a lot of people love cannabis for its sedating, chill-out effect.

That said, keep in mind that it can also have downsides, like short-term memory loss, sluggishness and lower motivation in some cases.

Beyond that, some people see the effects of this plant from a completely different angle.

Can weed also be a stimulant?

Cannabis is known for its ability to lift your mood, boost creativity and bring on euphoria. It can also be described as a drug that heightens the senses and can enhance sex and intimacy. Plenty of people see it as an energy boost, since it can make everyday tasks way more exciting and enjoyable.

But it's worth pointing out that some of weed's effects can be rough on the body. In some people it can cause:

• anxiety
• paranoia
• panic
• fear
• a faster heart rate
• trouble falling asleep because of a racing mind.
• To some degree, it can also bring on a “crash,” a kind of “weed hangover.”

So... is weed a hallucinogen too?

Generally, weed doesn't cause the dissociative, reality-bending effects associated with hallucinogens, but sometimes it can come close. If someone takes way too much, especially with edibles, they may experience effects similar to hallucinogens: time can seem to slow down, they can slip into a dreamlike state and they might even notice their grip on reality has loosened a bit.

Bottom line: it's hard to say weed belongs in the stimulant, depressant or hallucinogen category, since it seems to be in a class of its own, with elements of each. And the effects depend not just on the specific strain but on the person's body and how it responds.

That means some users may feel more upbeat on a strain while others feel the exact opposite, calm and relaxed, on the same flower. Others trying that same strain might feel neither upbeat nor calm, and instead get anxiety and paranoia, or just the munchies, or any of the other effects that come with cannabis.
