What is virtual reality?

Virtual reality is a simulated 3D environment that enables users to explore and interact with a virtual surrounding in a way that approximates reality, as it is perceived through the users' senses. The environment is created with computer hardware and software, although users might also need to wear devices such as helmets or goggles to interact with the environment. The more deeply users can immerse themselves in a VR environment -- and block out their physical surroundings -- the more they are able to suspend their belief and accept it as real, even if it is fantastical in nature.

The VR industry still has far to go before realizing its vision of a totally immersive environment that enables users to engage multiple sensations in a way that approximates reality. However, the technology has come a long way in providing realistic sensory engagement and shows promise for business use in a number of industries.

VR systems can vary significantly from one to the next, depending on their purpose and the technology used, although they generally fall into one of the following three categories:

Collaborative VR is sometimes cited as a type of virtual reality. In this model, people from different locations come together in a virtual environment to interact with one another, with each individual represented by a projected 3D character. The users typically communicate through microphones and headsets.

Augmented reality also is sometimes referred to as a type of virtual reality, although many would argue that it is a separate but related field. With augmented reality, virtual simulations are overlaid onto real-world environments in order to enhance or augment those environments. For example, a furniture retailer might provide an app that enables users to point their phones at a room and visualize what a new chair or table might look like in that setting.

Another category that is sometimes considered a type of virtual reality is mixed reality, which blends the physical and virtual worlds into a single space. Like augmented reality, however, it is more often considered a separate but related field. In fact, there's been a growing consensus to group virtual reality, augmented reality and mixed reality under the umbrella term "extended reality," which provides a handy way to reference all three, while still distinguishing among them.

Today's VR technologies and applications have inspired multiple companies and experts to advocate for advanced uses of the metaverse.

Virtual reality is often associated with gaming because the industry has been at the forefront of the VR effort, as evidenced by the popularity of products such as Beat Saber, Minecraft VR and Skyrim VR. Even so, there has been a growing interest in the potential of VR across a number of other areas:

The simplest form of virtual reality is a 3D image that can be explored interactively through a personal computer, usually by manipulating keys or the mouse so that the content of the image moves in some direction or zooms in or out. More sophisticated efforts involve such approaches as wraparound display screens, physical rooms augmented with wearable devices, or haptic devices that let users "feel" the virtual images.

Psychedelics: Risks, benefits, and more – Medical News Today

Posted: at 5:30 am

Psychedelics are a group of psychoactive drugs that can induce hallucinations and feelings of euphoria. Although some research suggests they can treat certain mental health conditions, they can cause dependence and be dangerous if misused.

Some cultures use psychedelics for religious and spiritual practices. People also use psychedelics for recreational purposes, although many psychedelic substances are controlled and illegal in the United States.

Emerging evidence suggests that certain psychedelics may have medicinal benefits for a range of health conditions, particularly common mental health conditions such as anxiety and depression.

This article discusses the characteristics, potential medicinal benefits, and risks of psychedelics.

Psychedelics are also known as hallucinogens because taking them can result in hallucinations. Hallucinations are sensory experiences that cause a person to see, hear, smell, taste, or feel things that are not really there. Someone who takes psychedelics may experience changes in their awareness of their thoughts and surroundings.

Some psychedelics come from plants or mushrooms (often referred to as magic mushrooms), while others are synthetic and manufactured by humans.

According to the National Institute on Drug Abuse (NIDA), there are two main types of psychedelics: classic hallucinogens and dissociative drugs.

Classic hallucinogens include substances such as:

LSD is a potent mind-altering chemical that is clear or white in color and has no smell. It is made from lysergic acid, which is found in a fungus that grows on grains.

Psilocybin is the main active ingredient in magic mushrooms, which include a wide range of mushrooms found in tropical and subtropical regions of South America, Mexico, and the U.S.

Peyote is a small cactus native to Mexico and southern regions of the U.S. It can also be synthetic.

It is used in some Native American religious ceremonies, but the Drug Enforcement Administration (DEA) restricts it as a Schedule I substance. It contains mescaline, which can cause hallucinations, altered body image, and euphoria.

DMT is a powerful chemical present in certain plant groups, including Phalaris, Delosperma, Acacia, Mimosa, and in the leaves of citrus plants. People can make a tea called ayahuasca, which is also known as hoasca, aya, or yag, from the natural plant version.

There is also a synthetic version of DMT, which is a white powder that people can smoke.

251-NBOMe is a synthetic substance originally developed by neuroscience researchers. It has similar qualities to LSD and MDMA. MDMA stands for 3,4-Methylenedioxymethamphetamine, and is a recreational psychoactive drug. However, 251-NBOMe is more powerful than LSD and MDMA.

Dissociative drugs include substances such as:

Surgeons used PCP in the 1950s as a general anesthetic, but manufacturers stopped producing it due to its serious side effects, which included postoperative delirium and hallucinations. At high doses, PCP can cause seizures, severe muscle contractions, violent or aggressive behavior, and symptoms of psychosis.

At lower doses, PCP can cause feelings of detachment from a persons surroundings and self, slurred speech, and loss of coordination. It is also a strong pain reliever.

The effects of PCP can develop within 25 minutes after smoking, and 3060 minutes after swallowing. Some people experience these effects for 48 hours.

It is an illegal, schedule II controlled drug. Its street names include:

A person can consume PCP by smoking, snorting, or swallowing the drug. It comes in powder, crystal, tablet, capsules, and liquid forms, with powder and liquid PCP being the most commonly sold forms.

Doctors and veterinarians use ketamine as an anesthetic for humans and animals undergoing surgery.

According to the DEA, most of the illegally-distributed ketamine is stolen from veterinary surgeries. It is often sold at parties, nightclubs, and raves. It is manufactured commercially as a liquid or powder. Liquid ketamine can be mixed into drinks. Powder ketamine can be smoked and snorted.

A person who takes ketamine may experience distortions to sights and sounds, feelings of dissociation, and a sense of calm. It also relieves pain.

It is also used to facilitate sexual assault and is also known as a date rape drug.

Its effects can last for 3060 minutes.

Its street names include:

DXM is found in a wide range of over-the-counter cold and cough medicines, such as syrups, tablets, and gel capsules. It is a cough suppressor that does not tend to cause side effects.

It is not an illegal or controlled substance because it is used to treat health conditions. When taken as a treatment for a cough, a typical dose for adults is between 1530 milligrams (mg), three to four times a day.

However, some people misuse DXM to achieve the feelings of euphoria it creates when taken in doses of 2501,500 mg much higher than the therapeutic range.

When a person takes DXM at these higher doses, it can have hallucinatory effects. It can also cause confusion, inappropriate laughter, agitation, paranoia, and a feeling of floating.

Salvia is a plant native to Mexico.

Its common street names are Maria Pastora, sally-D, and salvia.

People can smoke, chew, or vaporize Salvia, and its effects can come on quickly.

Some effects can include seeing bright lights and colors, shapes, and visual distortions of bodies or objects. It can also cause feelings of panic, fear, and paranoia, as well as hallucinations and uncontrollable laughter.

According to the DEA, Salvia is not a controlled substance under the Controlled Substances Act, although some U.S. states do control it.

Researchers have found a range of possible medical benefits of psychedelics, including:

An animal study published in Neuropsychopharmacologyin 2022 suggests that repeat doses of LSD over time can help to reduce stress-related anxiety and depression symptoms.

In terms of LSDs effects on humans, a 2018 study in Psychopharmacology found that people taking LSD in conjunction with having psychotherapy sessions reported increased feelings of happiness, trust, and empathy, resulting in positive social effects and altruism.

Furthermore, in 2019, the U.S. Food & Drug Administration (FDA) approved a drug closely related to ketamine, called esketamine, for treating severe depression in people for whom other treatments dont work.

Psilocybin may also be helpful in the treatment of depression and anxiety when these mental health conditions are specifically linked to life threatening diseases, according to a 2020 systematic review and meta-analyses of clinical trials in Biomedicines.

Authors of a 2017 study into the therapeutic effects of psilocybin stated that more research is needed to confirm whether this particular psychedelic can benefit OCD after a small, 2009 study stated it decreased OCD symptoms in all of its study participants.

The 2017 study stated that participants experienced reductions in their symptoms regardless of the dose they took and questioned whether the results were influenced by a placebo effect.

In a 2017 qualitative study in Harm Reduction Journal, researchers explored how alternative treatments, including psychedelics, could help people with migraine and cluster headaches. People using these substances for this purpose reported that psilocybin, LSD, and related psychedelics worked to prevent and treat cluster headaches and migraine.

According to a 2018 review, between the 1950s and 1970s, researchers carried out early phase studies investigating the effectiveness of classic psychedelics, but then discontinued their work. However, the evidence available from that time suggests that classic hallucinogens can be effective therapies, especially in the case of treating alcoholism with LSD.

Additionally, the authors of a 2020 systematic review found evidence to further support this therapeutic use.

This research presents encouraging evidence for the use of psychedelics in the treatment of a range of health conditions. However, researchers need to carry out more, and larger, well-designed clinical trials to help medical regulatory agencies decide whether to authorize psychedelics as medical treatments.

People who use psychedelics may experience one or several of a range of side effects, which range from moderate to severe. Along with the altered perception of reality that comes with hallucinations, which may be frightening to experience, short-term side effects of psychedelics can include paranoia and psychosis.

Psychedelic-induced psychosis can also persist in some people. These individuals can experience ongoing mental health issues, such as paranoia, altered mood, and visual disturbances.

Other people may experience a type of flashback known as Hallucinogen Persisting Perception Disorder (HPPD). The flashbacks can happen between a few days to over a year after the person took the psychedelics. People have sometimes mistaken the associated symptoms for a stroke or brain tumor.

In the most serious of cases, the long-term effects of using dissociative drugs, in particular, may include suicidal thoughts.

Psychedelics come in two main categories: classic hallucinogens and dissociative drugs. Emerging research suggests a range of potential therapeutic uses for psychedelics, from treating anxiety and depression to reducing the symptoms of OCD.

However, scientists need to carry out more clinical studies to investigate how effective psychedelics are for health conditions and the safety and long-term effects of psychedelics.

Additionally, many psychedelics are illegal and can cause dependence.
