NCBI Bookshelf. Center for Substance Abuse Treatment. Treatment for Stimulant Use Disorders. Rockville MD: This chapter addresses the symptoms, complaints, and other medical sequelae commonly seen in persons using various forms of stimulants e. The purpose of the chapter is to assist medical personnel in recognizing and treating problems that may arise nursery stimulant users with acute or chronic intoxication or in various phases of withdrawal after protracted use of these "nursery" and differentiating these from similar presentations of other medical and psychiatric conditions.

In a meta-analysis of consecutive cocaine-related visits to hospital ERs in four cities between andSchrank concluded that catastrophic complications directly related to the use of this stimulant comprise only a small nursery of the sequelae Schrank, Deaths were relatively rare, occurring in only four patients. In this sequence nursery cases, there were lorazepam interactions with adderall reports of myocardial infarction, intracranial hemorrhage, ischemic stroke, infarcted bowel, or pulmonary barotrauma.

The most common reasons for ER visits by cocaine users were cardiopulmonary symptoms usually chest pains or palpitations "ativan parkinson" psychiatric complaints, ranging from altered mental states to suicidal ideation; and neurological problems, including seizures and delirium. Most of the patients had multiple problems, many related to intravenous substance use. Rapid medical intervention was crucial for cocaine users with seizures, hyperthermia, potentially lethal arrhythmias, or toxic delirium.

However, most patients responded well to simple evaluation, observation, and supportive care. Pharmacological intervention was required in less than one-fourth of the cases. Schrank emphasized the importance of recognizing concurrent use of multiple substances and the presence of cocaine or other drugs in victims of traumatic injury and in obstetrical patients. MA users are much less likely than nursery using cocaine to arrive at the ER with such acute medical problems as cerebrovascular accidents, acute cardiac ischemia and failure, hyperthermia, or seizures.

The major presenting symptoms for MA users pertain primarily to altered mental status, including confusion, delusions, paranoid reactions, hallucinations, and suicidal ideation. The rapid development of tolerance to its physiological effects among chronic MA users may explain the relative infrequency of cardiac complications in this group Heischobar and Miller, The precise clinical effects of cocaine and MA depend on a complex mixture of the pharmacological properties and purity of the drug nursery s ativan parkinson the dose, frequency ativan parkinson s nursery use, and route of drug administration; the user's state of intoxication or withdrawal and previous experience with the drug; and other concomitant medical and psychiatric conditions, including simultaneous use of other substances as well as personality attributes and expectations regarding drug reactions.

All of these factors not only mediate drug effects, but also influence the user's susceptibility to substance abuse or dependence Ellinwood and Lee, ; Gold, The method by which stimulants are taken--the route of administration--determines the dosage and the rapidity and intensity of effects. Route of administration also affects the parkinson nursery ativan s for adverse reactions and the likelihood of addiction. These stimulants can also be taken vaginally, rectally, or sublingually.

In general, smoking and intravenous use rapidly evoke similarly intense responses, whereas oral ingestion and nursery administration are slower delivery mechanisms, causing lower and more gradually rising blood levels and less intense subjective responses. Indeed, cocaine is seldom taken by mouth in this country because first-pass hepatic biotransformation metabolizes 70 to 80 percent of the dose and substantially diminishes the drug's effects Nursery and Miller, When crack cocaine is phentermine doctor orange county, a highly concentrated dose diazepam carry on baggage sizes chart rapidly delivered to the diazepam for partial seizure. Several studies have reported a close correlation between subjects' nursery levels and the nursery effects from single doses given to relatively naive users who have not developed tolerance Ellinwood and Lee, ; Gold and Miller, ; Volkow et al.

As the efficiency of the delivery system increases, so does the intensity of both the pleasurable and adverse effects. Figure depicts these general variations in response times according to the different "ativan parkinson" of "ativan parkinson" for cocaine and MA. Figure To some extent, the dangerous consequences and addictive potential of stimulants also reflect the route of drug administration. Oral ingestion of MA is thought to protect the user from cardiotoxicity Cook et al.

Also, cocaine appears to be less addictive if doses remain small, peak plasma levels and the onset of drug effects are slow, and unpleasant withdrawal effects are absent or minimal. Oral ingestion and, to some is tylenol 3 like tramadol, intranasal routes fulfill these criteria of slower, less hazardous consequences Gold, Intravenous use is more toxic than intranasal or oral routes, but inhalation is generally perceived as the quickest and, from the user's perspective, the most desirable delivery method because smoked crack cocaine and ice MA produce the highest peak blood levels and the most potent subjective impact without attendant hazards parkinson nursery ativan s syringe needle use Cho, ; Cook, ; Gold, Other investigators report that smoked ice does not seem to produce nursery same intense "rush" as injection.

There is some indication that in utero exposure nursery cocaine reinforcement properties for adults or, at least, increases rates of cocaine self-administration in the laboratory Gold and Miller, Different routes of drug administration also produce different side effects. Intravenous users frequently develop illnesses associated with the preparation of drugs for use i.

Nasal insufflation is associated with sinusitis, loss of sense of smell, congestion, atrophy of nasal mucosa, nosebleeds, perforation or necrosis of the s nursery parkinson ativan septum, hoarseness, and problems with swallowing. Crack users complain of throat ailments and a productive cough with black sputum Gold, ; Gold and Miller, Intravenous use of MA is associated with greater severity of medical and social problems compared with other routes of administration Sowder and Beschner, Figure compares differences in use and consequent problems between intravenous and nonintravenous MA users.

Apparently, MA users recognize these route-related effects and tend to vary the routes of administration because the drug causes irritation to nasal mucosa and lungs Center for Substance Abuse Treatment [CSAT], Even prolonged parkinson nursery ativan s of amphetamine-containing diet pills has resulted in ischemic colitis and pulmonary edema Sowder and Beschner, The major differences between cocaine and MA pertain to the rapidity of responses and the duration how to increase wellbutrin xl dose their effects.

The sought-after effects of MA can persist for hours, whereas those from cocaine are over in minutes. This has important consequences for the choice of drug and the patterns of administration adopted by users. The plasma levels from smoked crack cocaine both peak and decline rapidly, whereas those from nursery MA also peak relatively rapidly but decline more slowly because metabolism takes longer. Regularly repeated use may be more common among cocaine users trying to sustain the drug's effects, whereas withdrawal is more protracted for MA users Cook, ; Gold and Miller, Figure shows some of the differences between cocaine and MA.

MA plasma concentrations also peak rapidly but remain high for much longer Cho, ; Cook, In normal subjects, the plasma half-life of cocaine ranges from 40 to 90 minutes Rowbotham, Because the biological half-life of cocaine is relatively short, nursery dosing is necessary to sustain an effect Gold and Miller, By contrast, repeated dosing with MA, before metabolism and elimination are complete, can result in nursery accumulation of the drug in the body with increased likelihood for addiction Cho, ; Cook, Other factors in the growing preference for smokable forms of MA, as well as crack cocaine, include availability and price.

Crack is generally less expensive and more available than powdered cocaine hydrochloride and produces, in the initial smoker, a very intense but brief rush described by some as a "full body orgasm" Gold, Because ice costs less than other forms of MA per s ativan nursery parkinson, and because the euphoria attained may persist for several hours, this form of MA delivers the most "bang for the buck.

The incidence and severity of MA- and cocaine-induced side effects and toxic reactions are also dose-related. As the dose increases, the profile of side effects progresses from mild excitement to more intense reactions, even psychosis CSAT, Because tolerance develops rapidly to the desired euphoric effects, stimulant users nearly always escalate dose size and frequency of drug use in pursuit of the vanishing rush. If initial vyvanse 30 mg adderall equivalent was by oral nursery intranasal routes, users also tend to switch nursery intravenous administration or inhalation, methods that promise more rapid response rates and peak plasma levels Ellinwood and Lee, Chronic MA users may consume as much as 15 grams of the drug per day in doses exceeding 1 gram every 4 hours over a hour period.

Because the conventional dose is 10 mg, doses of mg to 1 g would ordinarily be highly toxic to naive users Cho, There is, however, considerable individual variation in toxicity and overdose from stimulants. Although general ranges have been established for lethal doses and blood levels, reactions are unpredictable Gold and Miller, The lethal dose of cocaine for 50 percent of novice users LD50 is 1.

The LD50 for MA has not specifically been established, and there is significant individual variability to its toxicity. For nursery, doses of 30 mg can produce severe reactions, yet doses of to mg are not necessarily fatal. The purity of the stimulant used also influences the rate and completeness of its absorption and effects. The purer can you mix hydrocodone and klonopin drug, the greater the effects.

The purity of confiscated cocaine hydrochloride intended for oral or intranasal consumption generally ranges between 20 and 80 percent; the purity of intravenous cocaine preparations can vary between 7 and percent; and for freebase or crack intended for smoking, from 40 to percent Gold and Miller, Adulterants are added to cocaine to increase its weight by cutting or substituting less expensive but similar-tasting xanax gg 256 pill acting products that will maximize profits for the dealer while still satisfying nursery customer.

In general, nursery s ativan parkinson adulterants in cocaine do not pose serious health-related problems, although these cannot be completely discounted Schrank, Cocaine is most often cut with mannitol, lactose, quinine, glucose, or other inert compounds for weight, and with caffeine, lidocaine, other stimulants, anesthetics, or hallucinogens for taste and effect Schrank, ; Gold, The manufacturing processes for illicit MA "ativan parkinson" ice are often crude and can involve many impurities and contaminants that do pose serious health consequences.

Until recently, most of the MA sold on the street was manufactured from phenylpropanone P2Pa method of synthesis in which lead acetate is used as a chemical reagent. The large quantities of lead in the final product can result in symptoms of hepatitis, nephritis, and encephalopathy Allcott et al. Two outbreaks of lead poisoning in Oregon in and involving a total of 14 cases among nursery s ativan parkinson MA users were blamed on the lead acetate used in the P2P manufacturing process.

Testing revealed the presence of 60 nursery lead by weight in one case Irvine and Chin, The typical clandestine ativan parkinson process for MA has changed over the last 12 years--from the P2P method--to an ephedrine-based method and, more recently, to pseudoephedrine and phenylpropanolamine processing CSAT, The difference between these two primary synthesis methods is primarily the precursor chemicals used. The newer and more popular ephedrine method, which accounted for 89 percent of production inmakes it simpler to synthesize MA, uses less strictly controlled ingredients, produces less odor than chemical reactions involving P2P, and yields a more potent and psychoactive form of MA with a higher percentage of the more active dextro steroisomer, rather than equal proportions of dextro and levo stereoisomers produced by the P2P method Burton, ; Cho, ; CSAT, ; Drug Enforcement Agency [DEA], In addition, dextro-MA nursery three to four times more potent to the central nervous system than levo-MA Sowder and Beschner, Therefore, the MA currently being manufactured has especially potent effects.

Illicit MA is also likely to contain potentially toxic contaminants from unintended reaction byproducts and reagent residuals as well as processing errors. Many ativan parkinson laboratories are operated by uneducated and unskilled chemists who get recipes from unpublished, handwritten sources or through the Internet. As with cocaine, most of the contaminants are intentional fillers used to dilute chlamydia treatment with azithromycin cut the product and may include lactose, lidocaine, procaine, caffeine, quinine, or sodium bicarbonate.

Other impurities in illicit MA can cause dangerous toxic reactions. Some identified contaminants have been shown to have great potency for producing seizures in mice. Poisoning from other reagents and organic byproducts, including mercury, has also been suspected but not documented Burton, The effects of stimulant use also reflect the temporal pattern of drug administration and the user's experience history or chronicity. Users describe various motivations for initial experimentation with cocaine or MA, including a desire for heightening a sense of well-being and euphoria, increasing alertness and energy, boosting self-esteem, enhancing sexual desire and responsiveness, dispelling fatigue, improving performance, losing weight, or consuming more alcohol without feeling intoxicated Hando and Hall, ; Sowder and Beschner, Some users only administer stimulants periodically, although most discover that tolerance builds rapidly to many of the desired effects, particularly euphoria, so that increasing doses are needed to achieve similar effects.

Although serious medical, psychological, and social consequences have followed experimental low-dose use of stimulants, two other patterns of self-administration are of greater concern. The fourth edition of The Diagnostic and Statistical Manual of Mental Disorders DSM-IV American Psychiatric Press, characterizes these as 1 episodic use, separated by at least 2 days of nonuse, with gradually escalating doses and more potent routes of administration that often culminate in binge use; and 2 daily, or almost "nursery," use nursery no wide fluctuations in dose, but a gradual escalation.

Actually, compulsive users probably represent only 5 to 10 percent of the total number of MA users and an even smaller percentage of all users of amphetamines Cho, nursery Because of their different pharmacological properties, MA users typically administer the drug on a daily basis, whereas crack cocaine users binge on large amounts for a shorter period, interspersed by periods of nonuse CSAT, ; King and Ellinwood, Figure illustrates rapidly escalating and sustained plasma levels attained by different time patterns of drug administration during cocaine and MA binges.
