Understanding the Duration of Being High: A Definitive Guide

The experience of being "high" is a complex phenomenon that varies greatly among individuals. This altered state of consciousness, often associated with the consumption of psychoactive substances, can range from feelings of euphoria and heightened sensory perception to anxiety and paranoia.


The substances that can induce this state are diverse, including but not limited to cannabis, cocaine, LSD, MDMA, methamphetamine, alcohol, and certain prescription drugs. Each substance interacts uniquely with the brain's neurochemistry, leading to distinct physiological and psychological effects.


Understanding the duration of being high is a crucial aspect of substance use. This knowledge can inform decisions about consumption and help individuals anticipate and manage the effects of the substance. It can also aid in harm reduction, as knowing when the effects of a substance are likely to wear off can help prevent dangerous behaviours such as driving under the influence.


Furthermore, understanding the duration of being high can provide insights into the potential health risks associated with prolonged highs, such as dehydration, malnutrition, and mental health issues. A comprehensive understanding of how long being high lasts can contribute to safer, more informed substance use.


What Does Being High Mean?


 What Does Being High Mean


Being "high" refers to an altered state of consciousness, typically induced by consuming certain psychoactive substances. Changes in perception, mood, cognition, and behaviour characterise this state. The specific effects can vary widely, depending on the substance used, the individual's physiology, and the use context. Some common experiences include feelings of euphoria, relaxation, heightened sensory perception, altered time perception, and increased sociability. However, being high can also involve less desirable effects such as anxiety, paranoia, and impaired coordination.


Different Substances That Can Make You High


A wide range of substances can induce a high. These include both legal and illegal substances, as well as prescription medications. Cannabis, for instance, is known for causing a relaxed and euphoric high. Cocaine and methamphetamine, potent stimulants, produce a high characterised by intense euphoria, increased energy, and heightened alertness. 


Psychedelics like LSD and psilocybin mushrooms alter perception and cognition, often leading to profound changes in consciousness. Prescription drugs, such as opioids and benzodiazepines, can also induce a high when used outside medical guidelines. Understanding the diverse effects of these substances is crucial for informed and safe use.


Factors Influencing How Long Being High Lasts


Type of Substance Used


The type of substance consumed plays a significant role in determining the duration of the high. Different substances have different half-lives, which is the time it takes for the body to eliminate half of the drug from the system. For instance, the effects of cannabis can last anywhere from 1 to 6 hours, while the high from cocaine typically lasts about 15 to 30 minutes.


Method of Consumption


The method of consumption also influences how long the high lasts. Substances can be consumed in various ways, including inhalation, oral ingestion, injection, and transdermal application. Inhalation (smoking or vaping) and injection lead to rapid onset of effects but tend to wear off faster. In contrast, oral ingestion takes longer to produce effects but usually results in a longer-lasting high.


Individual's Metabolism


An individual's metabolism is another crucial factor. People with faster metabolic rates process substances more quickly, leading to a shorter high. Various factors, including age, sex, physical activity level, and genetic factors, can influence metabolism.


Tolerance Level


Tolerance level refers to the reduced response to a substance following repeated use. As tolerance develops, more of the substance is required to achieve the same effects, which can also influence the duration of the high. Chronic users may find that the high lasts for a shorter period compared to occasional users.


Body Mass


Body mass can also affect how long the high lasts. In general, substances are distributed throughout the body's tissues, and individuals with greater body mass may require larger doses to achieve the same effects. However, fat-soluble substances like THC, the active compound in cannabis, can be stored in fat tissues and released slowly over time, potentially prolonging the high.


Hydration and Nutrition


Finally, hydration and nutrition can influence the duration of the high. Adequate hydration can aid in metabolising and eliminating substances, potentially shortening the high. Similarly, certain nutrients can impact the body's ability to metabolise substances. For instance, consuming a meal before drinking alcohol can slow its absorption into the bloodstream, delaying the onset of effects and prolonging the duration of the high.


Understanding these factors can help individuals anticipate the duration of the high and make informed decisions about substance use. However, it's important to remember that the effects of substances can be unpredictable and vary greatly among individuals.


Duration of Being High Based on Different Substances




Cannabis, often consumed through smoking or ingestion, induces a high characterised by relaxation, euphoria, altered sensory perception, and increased appetite. The duration of a cannabis high can vary widely, typically lasting between 1 to 6 hours for smoked cannabis. However, the high from edibles can last much longer, often up to 12 hours, due to the slower absorption of THC through the digestive system.




Cocaine is a powerful stimulant that produces a high characterised by intense euphoria, increased energy, and heightened alertness. The effects of cocaine are typically short-lived, with the high usually lasting between 15 to 30 minutes when snorted. However, the method of consumption can influence the duration, with the high from smoking crack cocaine often lasting a shorter period, typically 5 to 10 minutes.




LSD (lysergic acid diethylamide) is a potent psychedelic that induces a high characterised by altered perception, intense emotional experiences, and visual hallucinations. The effects of LSD are long-lasting, typically persisting for 8 to 12 hours. The onset of effects usually occurs within 20 to 60 minutes of ingestion, reaching a peak at 2 to 4 hours and gradually tapering off.




MDMA, also known as ecstasy or molly, is a psychoactive drug that induces euphoria, increased empathy, and heightened sensory perception. The effects of MDMA typically begin within 30 to 60 minutes of ingestion and can last between 3 to 6 hours. Some users may experience lingering effects for several days after use.




Methamphetamine is a potent stimulant that produces a high characterised by intense euphoria, increased energy, and decreased appetite. The effects of methamphetamine can be long-lasting, with the high typically persisting for 6 to 12 hours. However, some users may experience effects for up to 24 hours.




Alcohol, a depressant, induces a high characterised by lowered inhibitions, relaxation, and impaired motor function. The duration of an alcohol high depends on several factors, including the amount consumed, the consumption rate, the individual's body mass, and the metabolic rate. Typically, the body metabolises alcohol at about one standard drink per hour.


Prescription Drugs


Prescription drugs, including opioids and benzodiazepines, can also induce a high when used outside medical guidelines. The duration of the high varies widely depending on the specific drug. For instance, the effects of Xanax, a benzodiazepine, can last up to 6 hours, while the high from OxyContin, an opioid, can last up to 12 hours.


The Science Behind Being High


 The Science Behind Being High


Psychoactive substances induce a high by interacting with the brain's neurochemistry. These substances can mimic or alter the function of neurotransmitters, the chemical messengers that transmit signals throughout the body to regulate a wide range of processes, from mood to motor control. For instance, opioids mimic endorphins, the body's natural painkillers, leading to feelings of relaxation and euphoria. Stimulants like cocaine and methamphetamine increase dopamine levels, a neurotransmitter associated with pleasure and reward, leading to intense euphoria and increased energy.


The Role of the Endocannabinoid System (for Cannabis)


Cannabis induces a high by interacting with the endocannabinoid system, a complex cell-signalling system that plays a crucial role in maintaining bodily homeostasis. The active compounds in cannabis, known as cannabinoids, bind to cannabinoid receptors in the brain and body. The most well-known of these cannabinoids, THC, binds to CB1 receptors in the brain, leading to the release of dopamine and the characteristic high. This interaction affects various aspects of cognition and perception, including memory, mood, sleep, appetite, and sensory perception.


Understanding the science behind being high can help individuals make informed decisions about substance use and better understand their experiences. However, it's important to remember that the effects of substances can be unpredictable and vary greatly among individuals. Always prioritise safety and legality when considering substance use.


The Health Risks of Prolonged Highs


Physical Health Risks


Prolonged highs can pose significant physical health risks. The exact risks depend on the substance used, but common issues include dehydration, malnutrition, and sleep disturbances. Some substances can also cause more severe health problems. For instance, stimulants like cocaine and methamphetamine can increase heart rate and blood pressure, potentially leading to heart attacks or strokes. Long-term cannabis use can lead to chronic bronchitis and other respiratory issues, particularly if smoked. Alcohol and certain prescription drugs can cause liver damage and other serious health problems when used excessively over time.


Mental Health Risks


In addition to physical health risks, prolonged highs can pose mental health risks. Many substances can cause anxiety and paranoia, particularly in high doses or during a bad trip. Long-term substance use can also lead to more serious mental health issues, such as depression, anxiety, and substance use disorders. Furthermore, some substances, particularly psychedelics like LSD, can trigger latent mental health issues in individuals predisposed to them.


How to Sober Up Safely 


How To Sober Up Safely




Hydration is crucial when trying to sober up. Many substances can cause dehydration, which can exacerbate feelings of grogginess or discomfort. Drinking water or electrolyte-rich drinks can help replenish lost fluids and aid the body in metabolising and eliminating the substance. However, avoiding drinking too quickly or excessively is important, as this can lead to water intoxication.




Rest is another important factor in sobering up. The body's processes, including the metabolism of substances, are most efficient during rest. Furthermore, many substances can cause fatigue as they wear off; rest can help alleviate this symptom. Even lying down and closing your eyes can help if it's difficult to sleep.




Eating can also aid in sobering up. Food can help absorb some substances, slowing their absorption into the bloodstream and reducing their effects. Furthermore, eating can help replenish nutrients lost during substance use and provide energy to combat feelings of fatigue. Choose balanced meals with a good mix of proteins, fats, and carbohydrates.


Seeking Medical Help


In some cases, medical help may be necessary to sober up safely. This is particularly true if the individual has consumed a large amount of a substance, is experiencing severe withdrawal symptoms, or has a co-occurring medical condition. If you or someone else is experiencing severe nausea and vomiting, chest pain, seizures, hallucinations, or difficulty breathing, seek medical help immediately.


The Role of Substance Use in Society


Social Acceptance of Substance Use


Substance use plays a complex role in society, with varying levels of social acceptance. Some substances, like alcohol and caffeine, are widely accepted and central to certain social rituals and traditions. Others, like cannabis, are gaining increasing acceptance, particularly in regions where they have been legalised for medicinal or recreational use. However, the use of these substances can still carry a social stigma, and their acceptance varies greatly by cultural, demographic, and individual factors.


The Stigma Around Being High


Despite the increasing acceptance of some substances, a significant stigma remains around being high. This stigma can manifest in various ways, from social exclusion and discrimination to internalised shame and guilt. It can also be a barrier to seeking help for substance-related issues, as individuals may fear judgment or misunderstanding. 


Challenging this stigma is crucial to fostering a more understanding and compassionate approach to substance use in society. This involves promoting education about substance use, advocating for fair drug policies, and supporting those struggling with substance use issues.


The Impact of Substance Use on Relationships


Substance use can significantly impact personal relationships. Being high can lead to behaviour, mood, and communication changes, which can strain relationships with friends, family, and partners. For instance, an individual might become more withdrawn, unpredictable, or irritable, leading to misunderstandings or conflicts. In some cases, substance use can also lead to neglect of responsibilities or broken trust, further damaging relationships.


The Role of Support Systems in Recovery


Support systems play a crucial role in recovery from substance use issues. The support of loved ones can provide emotional comfort, practical assistance, and motivation to seek help and maintain recovery. 


Support can come in many forms, from listening and offering encouragement to helping with practical tasks like attending appointments. Professional support, such as therapy and support groups, can also be essential to a comprehensive recovery plan. These resources can provide specialised guidance and a supportive community of individuals who understand the challenges of recovery. The role of support systems underscores the importance of maintaining healthy relationships and seeking help when dealing with substance use issues.


The Legal Implications of Substance Use


 The Legal Implications of Substance Abuse


The legal landscape of substance use is complex and varies widely by jurisdiction. Some substances, like alcohol and tobacco, are legal for adults to use in many parts of the world, while others, like cannabis, are legal in some places and illegal in others. Many substances, including cocaine, methamphetamine, and LSD, are illegal in most jurisdictions. Prescription drugs are permitted when used under the guidance of a healthcare provider, but their misuse can lead to legal consequences.


Consequences of Driving Under the Influence


Driving under the influence of substances is a serious crime with severe legal consequences. These include fines, license suspension, mandatory substance education programs, probation, and imprisonment. The specific penalties vary by jurisdiction and the specifics of the offence. Beyond the legal consequences, driving under the influence poses a significant risk to the safety of the driver, passengers, and others on the road. 


Understanding the legal implications of substance use is crucial to making informed decisions about substance use and mitigating potential risks.


Resources for Help and Support 


Hotlines and Websites for Immediate Help


Numerous hotlines and websites are available for immediate help with substance use issues. These resources can provide direct support, information, and referrals to local services. Examples include the Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline (1-800-662-HELP) and the National Institute on Drug Abuse (NIDA) website, which offers a wealth of information on different substances and their effects, as well as resources for finding treatment.


Long-Term Recovery and Support Options


Long-term recovery from substance use often involves medical treatment, counselling, and lifestyle changes. Medical treatments can include detoxification, medication-assisted treatment, and ongoing medical care for co-occurring health conditions. Counselling can involve individual therapy, group therapy, or family therapy and help individuals address the underlying issues contributing to substance use.


Support groups, such as Alcoholics Anonymous (AA) or Narcotics Anonymous (NA), can also be a valuable resource. These groups provide a supportive community of individuals who are also in recovery, offering a space to share experiences, challenges, and successes.


The Future of Substance Use and Research


Current research on substance use is multifaceted, encompassing the biological, psychological, and social aspects of substance use and addiction. On the biological front, researchers are delving into the neurochemical processes that underlie the high and the factors that influence the duration of the high. Psychologically, researchers are exploring the cognitive and emotional factors contributing to substance use and developing interventions to address these factors.


Future Implications for Understanding the Duration of Being High


Future research holds promising implications for understanding the duration of being high. As we gain a deeper understanding of the factors that influence the duration of the high, we can develop more effective harm-reduction strategies and treatment approaches.
