Controlled substance abuse

As an illegal, controlled substance, abuse of methaqualone can have serious social consequences for the user. Convictions carry heavy fines and possible jail time. Depending on the state, a conviction may also result in the suspension of the user s drivers license, and his or her constitutional right to vote may be revoked.

MACCS-II enables direct interface with other database management systems, such as the Relational Database Management System (RDBMS) and Oracle, so that databases which contain text and numeric data for which special interfaces are normally needed can be constmcted. Eor example, an Oracle MACCS-II linked system is currendy being used by the National Institute on Dmg Abuse (113) to develop a database that will allow scientists to determine the molecular stmctures of cocaine and other controlled substances as well as designer dmgs. 

Controlled substances are the most carefully monitored of all drugs. These drags have a high potential for abuse and may cause physical or psychological dependence Physical dependency is a compulsive need to use a substance repeatedly to avoid mild to severe witii-drawal symptoms it is die body s dependence on repeated administration of a drug. Psychological dependency is a compulsion to use a substance to obtain a pleasurable experience it is die mind s dependence on the repeated administration of a drag. One type of dependency may lead to die odier typa... 

The Controlled Substances Act of 1970 regulates die manufacture, distribution, and dispensing of drugs that have abuse potential (see information under Federal Drag Legislation and Enforcement in diis chapter). Drag under the Controlled Substances Act are divided into five schedules, based on their potential for abuse and physical and psychological dependence Display 1-2 describes the five schedules. 

Many laws have been enacted over the last century that affect drug distribution and administration. Those included here are the Pure Food and Drug Act Harrison Narcotic Act Pure Food, Drug, and Cosmetic Act and the Comprehensive Drug Abuse Prevention and Control Act. These laws control the use of the three categories of drugs in the United States (prescription, nonprescription, and controlled substances).

GHB has been used both for legitimate clinical and chnical research purposes and for a range of iUicit purposes. It was marketed legally in the United States until 1990, when the U.S. Food and Drug Administration (FDA) banned its sale to consumers. Except for the one indication described later in this section, GHB is a Schedule I controlled substance without other FDA-approved indications. The FDA has also declared y-butyrolactone (GBL) as a List I chemical and 1,4-butanediol (1,4-BD) as a Class I health hazard, practically designating these GHB precursors, which are also industrial solvents, as illicit and unapproved new drugs (National Institute on Drug Abuse 2000).

A number of medications have been studied to alleviate symptoms of stimulant withdrawal and the intense craving that may accompany it, but inconsistent results across controlled trials preclude any recommendations for their routine use. Patients with stimulant use disorders should be referred to substance abuse treatment because of the high risk for continued use either during or immediately following stimulant withdrawal.

Antihistamines such as diphenhydramine are known for their sedating properties and are frequently used over-the-counter medications (usual doses 25-50 mg) for difficulty sleeping. Diphenhydramine is approved by the FDA for the treatment of insomnia and can be effective at reducing sleep latency and increasing sleep time.43 However, diphenhydramine produces undesirable anticholinergic effects and carryover sedation that limit its use. As with TCAs and BZDRAs, diphenhydramine should be used with caution in the elderly. Valerian root is an herbal sleep remedy that has inconsistent effects on sleep but may reduce sleep latency and efficiency at commonly used doses of 400 to 900 mg valerian extract. Ramelteon, a new melatonin receptor agonist, is indicated for insomnia characterized by difficulty with sleep onset. The recommended dose is 8 mg at bedtime. Ramelteon is not a controlled substance and thus may be a viable option for patients with a history of substance abuse. 

Atomoxetine is similar to extended-acting stimulants in that it can be given once daily in many patients. Atomoxetine appears to lack any abuse potential and is not a controlled substance.22 One big disadvantage of atomoxetine is cost compared with other ADHD medications (Table 39-4). 

Fig. 22.1 Mechanisms underlying substance abuse. Addictive behavior is seen as a cyclical process where anticipation of the pleasure resulting from use of the drug leads to failure of the psychological mechanisms that usually control consumption. Excess quantities of drug are taken and an unpleasant withdrawal state arises when drug levels fall. This leads to...

Rao et al.20 demonstrated a fluorescence polarization immunoassay for evaluating serum concentrations of tricyclic antidepressants (amitriptyline, imipramine, clomipramine, and doxepin) with respect to nonresponse, compliance, therapeutic window, and influences of age, sex, substance abuse, and toxicity. Abbott Laboratories TDx/TDxFLx Toxicology Tricyclic Assay FPIA (fluorescence polarization immunoassay) was used. This assay of 50 /uL samples contained tricyclic antidepressant antibodies raised in rabbits and fluorescein-labeled tricyclic antidepressant as a tracer. The assay was calibrated with imipramine in the range of 75 to 1000 fig/L (268 to 3571 nmol/L). Intra-assay and inter-assay coefficients of variation for internal quality control samples from the manufacturer were 4.2 and 4.7%, respectively. The limits of detection were 72,71,64, and 72 nmol/L for amitriptyline, imipramine, clomipramine, and doxepin, respectively. This high-throughput immunoassay was easy to use although amitriptyline, dosulepine, desipramine, and nortriptyline showed cross-reactivities ranging from 74 to 100%. 

Controlled Substance Act and Controlled Substances Import and Export Act. Removed regulation of drug abuse from FDA (transferred to the Drag Enforcement Agency) and provided for stringent regulation of pharmaceuticals with abuse potential. 

Animals self-administer cathinone in a pattern common to abuses of monoamine stimulants such as cocaine (Woolverton and Johanson 1984). Cathinone can induce a conditioned place preference in rats (Schechter 1991). Withdrawal symptoms of khat include lethargy, depression, nightmares, and mild tremor (Kalix 1994). /V-methylated cathinone (methcathinone) is more potent, and has become available on the illegal market. It was subsequently scheduled as a controlled substance (Glennon et al. 1995).
