GHB Side Effects 

GHB Effects

GHB (Gamma Hydroxybutyrate) is a central nervous system (CNS) depressant that is often referred to as a “club drug” or “date rape” drug.

Teens and young adults most commonly abuse GHB to enhance their party experiences at clubs, bars, parties, and raves. Users usually use GHB by mixing its liquid form into an alcoholic beverage and drinking it. The liquid version of GHB is odorless and tasteless, making it a common drug used on unsuspecting victims to facilitate sexual assault. Our Delaware drug rehab is aware that sedatives like GHB are often taken for the high they produce. What many users don’t realize is that GHB side effects can be severe and can even include ailments like an addiction. 

What Does GHB Do?  

GHB works by increasing the neurotransmitter activity called gamma-aminobutyric acid (GABA), which carries messages between cells. However, GABA is also an inhibitory neurotransmitter, which means it blocks certain brain signals and decreases activity in the CNS. When a person takes GHB, GABA attaches to GABA receptors in the brain, producing a calming effect or high.  

GHB’s side effects make it a common recreational drug among people who like to party in nightclubs and raves because of the high it produces. Recreational GHB abuse is highly dangerous and can lead to addiction. Many people who begin casually using GHB often find themselves in need of medical detox. Its inhibitory impact on the body reduces a person’s ability to defend themself against sexual assault, making it a common date rape drug, as well. It can also cause memory loss, preventing victims from identifying their attackers. 

What Are the Side Effects of GHB? 

The GHB side effects usually begin about 15 to 30 minutes and intensify after 20 to 60 minutes.1 How long GHB stays in a person’s system and the intensity of its effects depends on the dose ingested and whether it’s mixed with other substances. 

Short-term effects of GHB include: 

  • Euphoria 
  • Relaxation and sedation 
  • Confusion 
  • Decreased blood pressure 
  • Memory loss 
  • Drowsiness 
  • Decreased body temperature 
  • Blacking out 
  • Loss of motor movement 
  • Headaches 
  • Increased sex drive 
  • Hallucinations 
  • Slurred speech 
  • Loss of balance and coordination 
  • Aggression and irritability 
  • Anxiety 
  • Nausea and vomiting 
  • Seizures 

GHB overdose is a common risk in users because it’s often mixed with alcohol. Using it frequently with other substances also increases the risk of dependence and physical complications. Memory deficiencies and other cognitive issues are common among long-time GHB users. 

Long-term effects of GHB include: 

  • Respiratory depression 
  • Memory loss 
  • Overdose 
  • Psychosis 
  • Increased blood pressure 
  • Tolerance 
  • Withdrawal 
  • Dependence and addiction 

GHB long-term effects also include addiction. More and more reports illustrate the addictive nature of GHB and its potential to cause withdrawal symptoms and overdose. Recreational drug use of any kind can be dangerous and life-threatening. Banyan Treatment Centers Delaware has helped numerous people recover from the effects of substance abuse with the help of our detox programs. 

GHB Side Effects: Next Day  

As a central nervous system depressant, GHB can lead to sedation and drowsiness. For this reason, it’s often used to facilitate sexual assault, most often by being placed in an unsuspecting victim’s drink. As a colorless liquid or white powder that is nearly undetectable when mixed into a liquid, and it’s, unfortunately, a popular date rape drug.  

However, people may also intentionally use GHB to get high, which is possible. The drug produces a sense of euphoria or extreme well-being, which keeps users hooked and wanting more. Once the effects wear off, users might take more doses, continuing the cycle.  

GHB side effects are usually felt within 10 minutes of ingestion and can last up to seven hours. The long duration of the high is what attracts users and makes the substance a popular drug of both abuse and sexual assault. However, the impact of GHB doesn’t dissipate when typical side effects do.   

Many victims of GHB-related date rape end up suspecting that they’ve been drugged because of the side effects they experience the following day. Common next-day GHB side effects may include dizziness, fatigue, and confusion. In addition, gaps in memory are especially common, as the after-effects of the drug are similar to those of a severe hangover.   

GHB is so sedative that an individual who was either unknowingly given high doses or has taken high doses of the drug may struggle to remember events from the night before. While they might be able to put together a string of memories, major gaps are common. This is another unfortunate reason why GHB is used as a date rape drug, as it makes it less likely that victims will remember the offender.  

Is GHB Addictive?  

GHB has a complex effect on the brain and body. As we previously mentioned, it works on different neurotransmitters or chemical messengers, especially gamma-aminobutyric acid (GABA). This chemical inhibits or blocks communication between brain cells, slowing down functions such as thinking, concentration, movement, and memory.  

Due to its impact on neurotransmitters in the brain, GHB has been classified as an illegal drug in the United States. Its addictive nature has also earned this classification, as a major long-term side effect is substance use disorder. This is marked by an inability to control one’s use of GHB, among other symptoms like severe cravings and withdrawal symptoms when the drug is not accessible.  

Withdrawals are often uncomfortable, so much so that the individual will continue using GHB – even if they’re aware of the harm it’s causing – simply to avoid them. Tolerance is also a common sign of GHB addiction and abuse.  

This becomes evident when the individual no longer experiences the same GHB side effects at their typical dosage and therefore requires a higher dosage to experience a high. Due to tolerance, doses tend to increase over time, making the development of an addiction and the risk of overdose significantly more likely.  

GHB Addiction Treatment  

GHB short-term effects and long-term effects can negatively impact other areas of an individual’s life in addition to their physical health. This includes their mental state, relationships, employment, school, and more.
