When does physical dependence on a drug occur?

Answer 1

Depending on the drug, the dose used, and a number of other factors physical dependence may not occur at all although when it does occur it typically requires at least several weeks of continuious use for physical dependence to start to set in. Continuous use of opioids, corticosteroids, beta- blockers, and alcohol nearly always lead to physical dependence sooner or later. Other drugs like benzodiazepines, contrary to popular belief, actually only cause significant physical dependence in about 1/3 of long-term users (even as long as two or more years). However people that abuse benzodiazepines and similar drugs have a greater chance of becoming physically dependent. It should also be clear that physical dependence is not that same as addiction. Many drugs including corticosteroids are not drugs of abuse yet continuous use can cause physical dependence in a matter of days when taken in moderate to large doses. Addiction is psychological dependence however many addicts addicted to drugs that tend to cause physical dependence like opioids will also be physically dependent. However most people prescribed opioids for a legitimate needed for a protracted period do not become addicted but do become physically dependent.

Answer 2

physical dependance is when you take a drug (not all drugs can cause physical dependance) too much and too often, and your body needs the drug to function normally. if you are physically dependant on a drug and you stop using it, you can have withdrawals from it and feel extremely sick until you take more of the drug. symptoms of withdrawals can include nausea, dizzyness, and just about any other bad symptom you can think of.

Answer 3

So substance abuse was a diagnosable condition in the DSM IV-R but was removed when the most current DSM (V) was published.
Substance Abuse was defined as a maladaptive pattern of substance use leading to clinically significant impairment or distress as manifested by one or more of the following, occurring within a 12-month period: • Recurrent substance use resulting in a failure to fulfill major role obligations at work, school, or home (e.g. repeated absences or poor work performance related to substance use; substance-related absences, suspensions, or expulsions from school; neglect of children or household) • Recurrent substance use in situations in which it is physically hazardous (e.g. driving an automobile or operating a machine when impaired) • Recurrent substance-related legal problems (e.g. arrests for substance-related disorderly conduct) • Continued substance use despite persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of the substance (e.g. arguments with spouse about consequences of intoxication, physical fights) Additionally, the symptoms for substance abuse have never met the criteria for substance dependence. Substance Dependence was defined as a maladaptive pattern of substance use leading to clinically significant impairment or distress is manifested by three or more of the following, occurring at any time in the same 12-month period: • Tolerance, as defined by either of the following: • A need for markedly increased amounts of the substance to achieve intoxication or desired effect • Markedly diminished effect with continued use of the same amount of the substance • Withdrawal, as manifested by either of the following: • The characteristic withdrawal syndrome for the substance • Taking the same (or a closely related) substance to relieve or avoid withdrawal symptoms • Taking the substance often in larger amounts or over a longer period than was intended • Having a persistent desire or unsuccessful efforts to cut down or control substance use American Psychiatric Association. Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV). American Psychiatric Association, Washington D.C., 1994, *The DSM criteria are presented as a reference to program directors to help them identify at risk residents. It is intended to trigger a referral for an evaluation. It does not imply that program directors should themselves evaluate and/or attempt to diagnose or manage a resident with substance abuse or substance dependence. We recommend program directors and faculty remain in their educational and evaluative roles avoid seeing the resident in a physician patient relationship which risks blurring the boundaries of both relationships. these diagnoses have been replaced with substance use disorder (specifying the substance being used) in the DSM V.
