Speedballs
Speedball (or powerball) is a polydrug mixture of a stimulant (most often cocaine or amphetamine) with an opioid (heroin, morphine, and/or fentanyl) that may be taken intravenously or by nasal Insufflation (medicine), insufflation. Original speedball combinations used cocaine hydrochloride mixed with morphine sulfate, while modern speedballs may also use pharmaceutical opioids, benzodiazepines, or barbiturates along with stimulants. Speedballs often give stronger effects than either drug when taken alone due to drug synergy, and are considered a particularly hazardous mixture that can easily cause myocardial infarction, heart attack, respiratory arrest and death. Evidence suggests that when compared to single drugs, speedballs are more likely to lead to addiction, and users are more likely to relapse and also to overdose. Physiological response Cocaine acts as a stimulant, whereas heroin/morphine acts as a depressant. Co-administration is meant to provide an intense Rush (psych ...

Polydrug
Polysubstance use or poly drug use or refers to the use of combined psychoactive substances. Polysubstance use may be used for entheogenic, recreational, or off-label indications, with both legal and illegal substances. In many cases one drug is used as a base or primary drug, with additional drugs to leaven or compensate for the side effects, or tolerance, of the primary drug and make the experience more enjoyable with drug synergy effects, or to supplement for primary drug when supply is low. Common combinations The most common psychoactive substances are alcohol, caffeine, cannabis, and nicotine (tobacco, and nicotine replacement therapy). Some of the absolutely most common polysubstance combinations are: * Alcohol combined with cannabis — known as ''cross-fading'' and may easily cause spins in people who are drunk and smoke potent cannabis. * Ayahuasca: DMT combined with MAOIs. * Caffeinated alcoholic drinks Combination drugs Some of the absolutely most common co ...

Jean-Michel Basquiat
Jean-Michel Basquiat (; December 22, 1960 – August 12, 1988) was an American artist who rose to success during the 1980s as part of the Neo-expressionism movement. Basquiat first achieved fame as part of the graffiti duo SAMO, alongside Al Diaz, writing enigmatic epigrams in the cultural hotbed of Manhattan's Lower East Side during the late 1970s, where rap, punk, and street art coalesced into early hip-hop music culture. By the early 1980s, his paintings were being exhibited in galleries and museums internationally. At 21, Basquiat became the youngest artist to ever take part in '' documenta'' in Kassel. At 22, he was one of the youngest to exhibit at the Whitney Biennial in New York. The Whitney Museum of American Art held a retrospective of his artwork in 1992. Basquiat's art focused on dichotomies such as wealth versus poverty, integration versus segregation, and inner versus outer experience. He appropriated poetry, drawing, and painting, and married text and image ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Healthline
Healthline Media, Inc. is an American website and provider of health information headquartered in San Francisco, California. It was founded in 1999, relaunched in 2006, and established as a standalone entity in January 2016. Accuracy There are questions about the quality and neutrality of their articles. One critic noted that a ''Healthline'' article about a new drug used promotional language, copied from the drug-maker's press release, neglected to cite side effects, and framed the drug's claimed benefits in misleading language not correctly representing the evidence reported in a peer-reviewed medical journal. Other critics have noted: * headlines that exaggerate the substance of the article; * inadequate journalistic and scientific skepticism when reporting "news"; * failure to balance quotes from vested interests with quotes from interviews of independent sources; * reported medical "news" that had not yet been validated by publication in a peer-reviewed journal; * impli ...

Respiratory Failure
Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing. Respiratory failure causes an altered mental status due to ischemia in the brain. The typical partial pressure reference values are oxygen Pa more than 80 mmHg (11 kPa) and carbon dioxide Pa less than 45 mmHg (6.0 kPa). Cause Several types of conditions can potentially result in respiratory failure: * Conditions that reduce the fl ...

Respiratory Depression
Hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate (''hypo'' meaning "below") to perform needed respiratory gas exchange. By definition it causes an increased concentration of carbon dioxide (hypercapnia) and respiratory acidosis. Hypoventilation is not synonymous with respiratory arrest, in which breathing ceases entirely and death occurs within minutes due to hypoxia and leads rapidly into complete anoxia, although both are medical emergencies. Hypoventilation can be considered a precursor to hypoxia and its lethality is attributed to hypoxia with carbon dioxide toxicity. Causes Hypoventilation may be caused by: *A medical condition such as stroke affecting the brainstem *Voluntary breath-holding or underbreathing, for example, hypoventilation training or the Buteyko method. *Medication or drugs, typically when taken in accidental or intentional overdose. Opioids and benzodiazepines in particular are known to cause respiratory depress ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sedation
Sedation is the reduction of irritability or agitation by administration of sedative drugs, generally to facilitate a medical procedure or diagnostic procedure. Examples of drugs which can be used for sedation include isoflurane, diethyl ether, propofol, etomidate, ketamine, pentobarbital, lorazepam and midazolam. Medical uses Sedation is typically used in minor surgical procedures such as endoscopy, vasectomy, or dentistry and for reconstructive surgery, some cosmetic surgeries, removal of wisdom teeth, or for high-anxiety patients. Sedation methods in dentistry include inhalation sedation (using nitrous oxide), oral sedation, and intravenous (IV) sedation. Inhalation sedation is also sometimes referred to as ''relative analgesia''. Sedation is also used extensively in the intensive care unit so that patients who are being ventilated tolerate having an endotracheal tube in their trachea. It can also be used during a long term brain EEG to help patient relax. Risks There are ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anxiety
Anxiety is an emotion which is characterized by an unpleasant state of inner turmoil and includes feelings of dread over anticipated events. Anxiety is different than fear in that the former is defined as the anticipation of a future threat whereas the latter is defined as the emotional response to a real threat. It is often accompanied by nervous behavior such as pacing back and forth, somatic complaints, and rumination. Anxiety is a feeling of uneasiness and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing. It is often accompanied by muscular tension, restlessness, fatigue, inability to catch one's breath, tightness in the abdominal region, nausea, and problems in concentration. Anxiety is closely related to fear, which is a response to a real or perceived immediate threat (fight or flight response); anxiety involves the expectation of future threat including dread. People facing anxiety may withdraw fro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Euphoria
Euphoria ( ) is the experience (or affect) of pleasure or excitement and intense feelings of well-being and happiness. Certain natural rewards and social activities, such as aerobic exercise, laughter, listening to or making music and dancing, can induce a state of euphoria. Euphoria is also a symptom of certain neurological or neuropsychiatric disorders, such as mania. Romantic love and components of the human sexual response cycle are also associated with the induction of euphoria. Certain drugs, many of which are addictive, can cause euphoria, which at least partially motivates their recreational use. Hedonic hotspots – i.e., the pleasure centers of the brain – are functionally linked. Activation of one hotspot results in the recruitment of the others. Inhibition of one hotspot results in the blunting of the effects of activating another hotspot. Therefore, the simultaneous activation of every hedonic hotspot within the reward system is believed to be ...

Rush (psychology)
In psychology, a rush is an acute transcendent state of euphoria. A wide variety of recreational drugs are commonly capable of such an event. These drugs include, but are not limited to, opioids (particularly heroin) and psychostimulants (particularly methamphetamine and cocaine). A 2017 study involving fifty six female clients were interviewed by Nicholas E. Goeders suggests that the subjective rush from recreational methamphetamine use is proportional to the rate at which the blood level of the drug increases. Goeders concluded that "Without a doubt methamphetamine, when injected in “sufficient” purity and dose, can produce a subjective physiological response in women that is indistinguishable from an orgasm." Intravenous injection is the fastest route of administration, causing blood concentrations to rise the most quickly, followed by smoking, suppository (anal or vaginal insertion), insufflation (snorting), and ingestion (swallowing).

Depressant
A depressant, or central depressant, is a drug that lowers neurotransmission levels, which is to depress or reduce arousal or stimulation, in various areas of the brain. Depressants are also colloquially referred to as downers as they lower the level of arousal when taken. Stimulants or "uppers" increase mental or physical function, hence the opposite drug class of depressants is stimulants, not antidepressants. Depressants are widely used throughout the world as prescription medicines and as illicit substances. Alcohol is a very prominent depressant. Alcohol can be and is more likely to be a large problem among teenagers and young adults. When depressants are used, effects often include ataxia, anxiolysis, pain relief, sedation or somnolence, and cognitive or memory impairment, as well as in some instances, euphoria, dissociation, muscle relaxation, lowered blood pressure or heart rate, respiratory depression, and anticonvulsant effects. Depressants also act to produce anes ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
