What Does GHB Do?

After actress Cara Delevingne spoke about her experience of withdrawal from GHB, in which she experienced seizures before entering recovery, attention has again been brought to the dangers of the drug.

GHB has been linked to being used as a date rape drug, but it is also used recreationally, despite carrying serious health risks.

Many people have heard of GHB but are unsure of its effects or risks, so it’s important to know exactly how GHB affects the body and brain and recognise when you may need professional support.

 

What Is GHB?

GHB (gamma-hydroxybutyrate) is a central nervous depressant that is used medically to treat narcolepsy.

More commonly, it is used recreationally to get high. It is seen as a rave drug or club drug, used to enhance the experience of an intense night out of dancing, bright lights and drinking.

The most common form you find it in is as a clear liquid that is sold in small bottles. Due to its effects, it is known as “liquid ecstasy”.

 

What Does GHB Do to the Body and Brain?

GHB acts on the central nervous system, slowing down messages from the brain to the body, causing feelings of relaxation and sedation. It also works by stimulating the release of dopamine, bringing on feelings of euphoria, increased sociability and feeling disinhibited.

How GHB will affect you is not always obvious, as the effects can vary significantly, depending on dosage and individual factors such as your weight and metabolism.

 

How Long Do the Effects of GHB Last?

As stated above, GHB takes around 10 minutes for the effects to really be felt by the user. Typically, the effects last up to 4 hours before they peak after 30 minutes to an hour.

How long the effects last is down to several factors, including:

• Dosage
• Body weight
• Metabolism
• Whether you’ve been using other substances

As GHB effects peak after an hour, this fairly short duration means that people often use it again when previous doses have not been safely metabolised, bringing risks of overdose and over-intoxication.

 

What Does GHB Feel Like?

At lower doses, people commonly experience:

• Feelings of calmness
• Euphoria
• Increased sex drive
• More social
• Lack of inhibition

At higher doses, people commonly experience:

• Confusion
• Hallucinations
• Sedation
• Loss of consciousness

Experiences can differ between people due to their build and weight, the potency of their dose, their metabolism, whether they are using other substances as well and repeated use.

 

What Are the Risks and Side Effects of GHB?

GHB is a dangerous drug that comes with negative side effects. Common symptoms that people don’t want to experience but do include:

• Nausea and vomiting
• Confusion
• Memory impairment
• Loss of coordination
• Slowed breathing
• Extreme drowsiness

These effects are common because there is a small window, dosage-wise, for the desired effects. If you increase the dosage even a small amount, you significantly increase the risk of experiencing the side effects listed above.

 

Can GHB Cause Overdose?

Due to the narrow margin between a recreational dose and a dangerous dose, overdoses can occur more commonly than you might think.

It’s vital to know the signs of overdose, so that you can act if it occurs. You should look out for overdose signs such as:

• Unconsciousness
• Breathing difficulties
• Seizures
• Unresponsiveness
• Sweating a lot
• Unable to stand
• Becoming incoherent

If you see someone displaying these symptoms, get help by seeking immediate emergency medical assistance to avoid a potentially fatal outcome.

 

Why Is Mixing GHB with Alcohol So Dangerous?

GHB is a depressant, so it becomes infinitely more dangerous when you mix it with alcohol or another depressant substance.

This is because, combined, they amplify sedative effects and increase the likelihood of overdose, increasing sedation and leading you to stop breathing. As they compound those effects, that means if you are drinking and using GHB, even a safe amount may result in you overdosing or suffering from a medical emergency.

 

Can You Become Addicted to GHB?

GHB is addictive because it acts on your brain, releasing neurotransmitters that you’ll come to crave the heightened levels the substance causes.

You’ll develop a tolerance as you take GHB again and again to feel the same effects, using more as your body becomes used to the drug in your system. Over time, this physical dependence develops, and you’ll experience withdrawal if you stop taking GHB.

Eventually, your use progresses to an addiction as the taking of GHB becomes compulsive. You lose all control and continue to use GHB despite the negative effects it is having on your life.

There is no predicting why people become addicted to GHB. It can happen for many reasons, including:

• Regular use, as you often go to nightclubs or raves (settings where GHB use is more common
• Coping strategies for mental health and physical issues
• Dealing with trauma
• Peer pressure

 

What Are the Immediate Effects of GHB?

GHB takes around ten minutes to kick in and lasts hours, which means you feel the effects nearly immediately.

Common short-term effects of GHB include:

• Relaxation
• Euphoria
• Increased sociability
• Drowsiness
• Reduced anxiety
• Dizziness
• Impaired coordination
• Slurred speech
• Confusion

With its short onset and long duration, it can be very easy to overdose on GHB. You should wait at least two hours after your last dose before having another, and you only need a small amount to feel effects, so the safe dosage can be difficult to judge.

 

What Are the Signs of GHB Addiction?

Addiction can come to impact every aspect of your life. It can lead to poor physical and mental health, cause a breakdown in your relationships, and lead you into financial and legal troubles.

There comes a point where it can stop you from functioning day-to-day. Knowing the signs of addiction lets you act before things get worse

GHB addiction symptoms to look out for include:

• Frequent cravings
• Increasing use
• Loss of control over GHB consumption
• Continued use despite negative consequences
• Withdrawal symptoms between doses

 

What Happens During GHB Withdrawal?

In her interview, Cara Delevingne spoke about the seizures she experienced while going through withdrawal. GHB withdrawal can be intense and is medically very serious, so you must be informed and safe.

GHB withdrawal symptoms include:

• Anxiety
• Agitation
• Insomnia
• Tremors
• Rapid heart rate
• Confusion
• Hallucinations
• Psychosis

GHB withdrawal can be very dangerous, with physical and psychological symptoms being severe.
