Substance abuse tolerance

Eszopiclone is available in 1-, 2-, and 3-mg tablets for oral administration. The maximum recommended dose is 3 mg/night. In the elderly, this dose is reduced to maximum of 2 mg. No evidence of tolerance or dependence has been reported, but long-term use should be approached with caution. In addition, eszopiclone should be used cautiously in substance abuse patients because trials have shown euphoric effects at high doses. 

Buspirone tends to be used preferentially in patients with chronic and persistent anxiety, in patients with comorbid substance abuse, and in elderly patients, because it is well tolerated and has no significant pharmacokinetic drug interactions. What is clear is that buspirone shows reproducible efficacy in certain animal models of anxiety and in GAD, which points to a potentially important role of serotonin in mediating anxiety symptoms through 5HT1A receptors. Buspirone also has a role as an augmenting agent for the treatment of resistant depression, as discussed in Chapter 7. 

Abuse is the maladaptive pattern (over at least a 12-month period) of substance use, leading to impairment or distress, but this does not include substance dependence, tolerance, or withdrawal.

SAD can present in children of preschool to elementary school age. If the disorder is not treated, it can persist into adulthood and increase the risk of depression and substance abuse. CBT and social skills training are effective nonpharmacological therapies in children. Pharmacological evidence is limited to case studies or open-label trials. SSRIs are considered first-line therapy because of tolerability and effectiveness. Fluoxetine, fluvoxamine, sertraline, and paroxetine were effective in children with SAD. Headache, nausea, drowsiness, insomnia, jitteriness, and stomach aches were reported in children receiving SSRIs. 

By its nature, a self-admission program is at odds with a zero-tolerance policy. Once a driver admits to having a substance abuse problem, you have actual knowledge that they have used drugs or abused alcohol, and a zero-tolerance policy would dictate that you release the employee immediately. 

The consequences for drivers found to have violated Subpart B of this Part, including the requirement that the driver be removed immediately from safety-sensitive functions, and the procedures under Part 40, Subpart 0, of this title. (9) Your policy must clearly state what the consequences are to a driver who violates the prohibitions listed in Subpart B of Part 382. For carriers that have a zero-tolerance policy, this is simple — you will provide the driver with a list of substance abuse professionals, and then terminate employment. For carriers that do not terminate, you must detail your SAP program in your written policy. 

Description It has been well documented that drivers under the influence of alcohol or drugs have been involved in about half of all fatal traffic accidents. Drinking or substance abuse by drivers of alcohol or drugs cannot be tolerated. Company management must be acutely aware of the seriousness of this societal problem and establish procedures to effectively control it within their respective organizations. 

Employee morale. An organization that tolerates substance abusers runs the risk of losing conscientious and hardworking staff. Over time, the best workers will tire of working harder while substance abusers produce less and enjoy more time off. An estimated 3.1 percent of employed adults admit they ve used illicit drugs before reporting to work and 7.1 percent say they drank on the job one or more times in the past year, according to sources cited by the US Department of Labor. 

A formal diagnosis of substance dependence requires a maladaptive pattern of abuse that leads to clinically significant impairment or distress. More detailed criteria revolve around the development of tolerance, the experience of withdrawal when abstinence is required, the inability to stop using the drug, and continued use over a protracted period of time. The question is whether or not these criteria, clearly applicable to cocaine, heroin, and other drugs, are met by caffeine. 

Given the low incidence of severe withdrawal symptoms and the modest effects on the mesolimbic dopamine (reward) system, most investigators have found that cannabis has a low abuse or addiction potential. However, it has been argued that if cannabis is a non-addictive substance, why is its use so widespread and why are there so many longterm and heavy users Finally, contrary to the evidence that cannabis can produce chronic tolerance, some regular users report that they require less drug to achieve the same high, or sensitisation (Chapter 3). Three possible explanations may account for this. First, chronic users may focus on the effects that they wish to achieve. Second, the...
