It may seem like a doomed attempt to mix business and pleasure. But a growing number of young professionals in Silicon Valley insist that taking small doses of psychedelic drugs simply makes them perform better at work – becoming more creative and focused. The practice, known as “microdosing”, involves taking minute quantities of drugs such as LSD, psilocybin (magic mushrooms) or mescaline (found in the Peyote cactus) every few days.

LSD is the most well-known psychedelic drug since its popularity in the heyday of 1960s counterculture. But perhaps somewhat surprisingly, Silicon Valley also has a long history of psychedelic drug use to boost creativity: technology stars Steve Jobs and Bill Gates both famously experimented with LSD.

At high doses, LSD powerfully alters perception, mood and a host of cognitive processes. LSD now appears to be one of the more commonly microdosed drugs. A microdose of LSD consists of about a tenth of a recreational dose (usually 10-20 micrograms), which is usually not potent enough to cause hallucinations. Instead, it is reported to heighten alertness, energy and creativity.

Microdosing LSD also purportedly enhances overall well-being, helping to reduce stress and anxiety while improving sleep and leading to healthier habits. Although a widely reported phenomenon in the media, the lack of scientific studies on microdosing makes the prevalence near impossible to estimate. Reports suggest that what started off as an underground practice in Silicon Valley may be spreading rapidly to other workplaces.

It is currently unknown how such low doses of psychedelics act in the brain to produce these intriguing self-reported effects on creativity. Like all classic hallucinogens, LSD produces its potent mind-altering effects primarily by mimicking the effects of the brain chemical serotonin, which regulates our mood. In particular, LSD activates 5-HT2A receptors in the pre-frontal cortex, which increases activity of the chemical glutamate in this region. Glutamate enables signals to be transmitted between nerve cells, and plays a role in learning and memory.

In humans, two distinct effects of recreational doses of LSD have been reported. Initially, people experience psychedelic and positive feelings of euphoria. This may be followed by a later phase characterised by paranoia or even a psychotic-like state. LSD at low doses may produce mood elevation and creativity, mediated by the serotonin-mimicking effects. Actions on both glutamate and serotonin may also act to improve learning and cognitive flexibility, necessary for creativity, in the workplace. These findings could partly help to explain the microdosing phenomenon.

Clinical research with psychedelics is currently undergoing a major revival after having been brought to a halt in the 1960s. One of the benefits of conducting research into psychedelics is their potential to help deepen our understanding of consciousness. In 2016, researchers from Imperial College London were the first to use brain scanning techniques to visualise how LSD alters the way the brain works. One key finding was that LSD had a disorganising influence on cortical activity, which permitted the brain to operate in a freer, less constrained manner than usual.

The results suggested that psychedelics increase communication between parts of the brain that are less likely to communicate with one another, and decrease communication between areas that frequently do. This likely underlies the profound altered state of consciousness that people often describe during an LSD experience. It is also related to what people sometimes call “ego-dissolution”, in which the normal sense of self is broken down. People instead often report a sense of reconnection with themselves, others and the natural world.

The discovery that LSD and other psychedelic drugs induce a flexible state of mind may explain their reported extraordinary therapeutic benefits. For example, psilocybin has shown benefits in the treatment of tobacco and alcohol addiction, obsessive compulsive disorder and treatment-resistant major depression.

In a small pilot study, LSD in combination with psychological therapy also led to a slight improvement in anxiety experienced by terminally ill cancer patients. Many of these psychiatric disorders are characterised by inflexible, habitual patterns of brain activity. By introducing a disordered state of mind, LSD and other psychedelics may help to break these inflexible patterns.

Similarly, the unconstrained brain state induced by psychedelics may also help explain the reported increases in creativity. From the late 1950s until the early 1970s, a whole host of studies sought to determine if classic psychedelics could be useful for enhancing creativity. In the most notable of these studies, researchers found that LSD and mescaline could aid in creative problem-solving when used in carefully controlled settings.

However, while these studies do provide some insight, they are merely anecdotal by modern research standards (they were not double blind or placebo-controlled). A more recent study found that use of classic psychedelics was robustly associated with greater creative problem-solving ability. Enhancing creativity has many potential applications in society. For example, it could be both used by commercial industry including advertising and in clinical settings, such as helping patients with autism.

World's 10 deadliest street drugs Show all 10 1 /10 World's 10 deadliest street drugs World's 10 deadliest street drugs Whoonga Whoonga is a combination of antiretroviral drugs, used to treat HIV, and various cutting agents such as detergents and poisons. The drug is widely available in South Africa due to South Africa’s high rate of HIV sufferers, and is believed to be popular due to how cheap it is when compared to prescribed antiretrovirals. The drug is highly addictive and can cause major health issues such as internal bleeding, stomach ulcers and ultimately death Getty World's 10 deadliest street drugs Scopolamine Scopolamine is a derivative from the nightshade plant found in the Northern Indian region of South America (Ecuador, Colombia and Venezuela). It is generally found in a refined powder form, but can also be found as a tea. The drug is more often used by criminals due its high toxicity level (one gram is believed to be able to kill up to 20 people) making it a strong poison. However, it is also believed that the drug is blown into the faces of unexpecting victims, later causing them to lose all sense of self-control and becoming incapable of forming memories during the time they are under the influence of the drug. This tactic has reportedly been used by gangs in Colombia where there have been reports of people using scopolamine as way to convince victims to rob their own homes World's 10 deadliest street drugs Heroin Founded in 1874 by C. R. Alder Wright, heroin is one of the world’s oldest drugs. Originally it was prescribed as a strong painkiller used to treat chronic pain and physical trauma. However in 1971 it was made illegal under the Misuse of Drugs Act. Since then it has become one of the most destructive substances in the world, tearing apart communities and destroying families. The side effects of heroin include inflammation of the gums, cold sweats, a weak immune system, muscular weakness and insomnia. It can also damage blood vessels which can later cause gangrene if left untreated World's 10 deadliest street drugs Crack cocaine Crack cocaine first came about in the 1980’s when cocaine became a widespread commodity within the drug trafficking world. Originally cocaine would have attracted a high price tag due to its rarity and difficulty to produce, but once it became more widespread the price dropped significantly. This resulted in drug dealers forming their cocaine into rock like shapes by using baking soda as a way of distilling the powder down into rock form. People were doing this because it allowed for them to sell cocaine at a lower quantity and to a higher number of people. The side effects of crack cocaine include liver, kidney and lung damage, as well as permanent damage to blood vessels, which can often lead to heart attacks, strokes, and ultimately death World's 10 deadliest street drugs Crystal meth Not just famous because of a certain Walter H White, but also because it is one of the most destructive drugs in the world. First developed in 1887, it became widely used during the Second World War when both sides would give it to their troops to keep them awake. It is also believed that the Japanese gave it to their Kamikaze pilots before their suicide missions. After the war crystal meth was prescribed as a diet aid and remained legal until the 1970s. Since then it has fallen into the hands of Mexican gangs and has become a worldwide phenomenon, spreading throughout Europe and Asia. The effects of crystal meth are devastating. In the short-term users will become sleep depraved and anxious, and in the long-term it will cause their flesh to sink, as well as brain damage and damage of the blood vessels World's 10 deadliest street drugs AH-7921 AH-7921 is a synthetic opioid that was previously available to legally purchase online from vendors until it became a Class A in January 2015. The drug is believed to have 80% of the potency of morphine, and became known as the ‘legal heroin’. While there has only been one death related to AH-7921 in the UK, it is believed to be highly dangerous and capable of causing respiratory arrest and gangrene World's 10 deadliest street drugs Flakka Flakka is a stimulant with a similar chemical make-up to the amphetamine-like drug found in bath salts. While the drug was originally marketed as a legal high alternative to ecstasy, the effects are significantly different. The user will feel an elevated heart rate, enhanced emotions, and, if enough is digested, strong hallucinations. The drug can cause permanent psychological damage due to it affecting the mood regulating neurons that keep the mind’s serotonin and dopamine in check, as well as possibly causing heart failure World's 10 deadliest street drugs Bath salts Bath salts are a synthetic crystalline drug that is prevalent in the US. While they may sound harmless, they certainly aren’t the sort of salts you drop into a warm bath when having a relaxing night in, they are most similar to mephedrone, and have recently been featured throughout social media due to the ‘zombification’ of its. The name comes from the fact that the drug was originally sold online, and widely disguised as bath salts. The side effects include unusual psychiatric behaviour, psychosis, panic attacks and violent behaviour, as well as the possibility of a heart attack and an elevated body temperature World's 10 deadliest street drugs Purple Drank One of the more unusual drugs around at the moment, purple drank was popularised in 90s hip hop culture, with the likes of Jay Z and Big Moe all mentioning it in their songs. It is a concoction of soda water, sweets and cold medicine, and is drunk due to cold medicines high codeine content, which gives the user a woozy feeling. However it can also cause respiratory issues and heart failure World's 10 deadliest street drugs Krokodil Krokodil is Russia’s secret addiction. It is believed that over one million Russians are addicted to the drug. Users of krokodil are attracted to the drug due to its low price; it is sold at £20 a gram while heroin is sold for £60. However, krokodil is considered more dangerous than heroin because it is often homemade, with ingredients including painkillers, iodine, lighter fluid and industrial cleaning agents. This chemical make-up makes the drug highly dangerous and likely to cause gangrene, and eventually rotting of the flesh

Yet before rushing off to take hits of acid in the hopes of boosting our creativity at work, it should be remembered that microdosing with an illegal, unregulated drug is of course fraught with risks. Possession may get you put behind bars. Manufacture and supply of illegal drugs are not subject to rigorous regulatory controls. That means users can never be sure of what they are getting.

This makes determining the dose problematic. Those who microdose incorrectly risk having unwanted, full-blown trips or even experience unpleasant trips. There are even some reports of psychosis-like symptoms in certain vulnerable individuals who use LSD recreationally. However two recent US population surveys found no link between using psychedelics and mental health conditions.

In an increasingly competitive world it is tempting to find a quick fix to help us achieve more, better and faster. Yet, is this right? As a society we should consider the reasons as to why healthy people choose to use drugs in the first place. A reliance on cognitive-enhancing technologies to cope with demanding working conditions may ultimately reduce the health and well-being of individuals. So we must take care to ensure that enhancement is not seen as a substitute for a healthy working environment.

It is therefore important that more research is done on the safety and efficacy of microdosing. In the meantime, physical exercise, education, social interaction, mindfulness and good quality sleep have all been shown to improve cognitive performance and overall well-being.
