Evidence of escalating use (frequency), tolerance (how many drinks before intoxicated), habituation, or physiologic dependence (presence of withdrawal signs or symptoms when abstaining)
Attempts to cut back on use or abstain; remorse after use; consumption of more alcohol or drug than intended on more than one occasion; setting up conditions to attempt to limit use (e.g., "I’m only drinking beer" or "I’m only using on weekends")
Cravings or a subjective sense of compulsion to use; planning social occasions to use

Adverse life consequences
As a result of substance abuse, loss of or damage to health (including mental health—depression that doesn’t seem to get better); loss of or damage to family relationships, social relationships; damage to education or career, finances, or religious practice; family or employer concerns; or legal problems related to use (divorce, loss of child custody, driving under the influence, public intoxication, domestic abuse)
Minimization of use, justification or rationalization of use, inability to acknowledge the consequences of use, euphoric recall (i.e., remembering only the pleasant aspects of abusing a substance), suppression or repression of painful affect, enabling behaviors among social support network, cognitive impairments, including memory distortions (e.g., blackouts)

Alcoholic drinking patterns
Drinking before attending social functions where alcohol will be served
Solitary or secret drinking; hidden bottle or supply
Morning drinking or morning tremor
Daily use or "binge" drinking
Drinking in inappropriate circumstances or to cope with stressors

>100 mg/dL (0.1%) in a patient coming in for a general examination
>150 mg/dL (0.15%) in a patient without signs of intoxication
>300 mg/dL (0.3%) in a patient under any circumstances
The drug screen is a specific assay for a finite number of compounds. Drugs may be detected in urine, plasma, gastric juices, or other body fluids if the volume available is large enough. In general, urine testing is used to screen for the presence of compounds, with confirmation by assaying serum or plasma samples.

Screening for drugs of abuse
The survey is useful as a quick screen for the presence of major categories of drugs of abuse. The Drug Abuse Survey is a urine test for alcohol, amphetamines, barbiturates, benzodiazepines, cocaine, opiates, phencyclidine, and tetrahydrocannabinol (THC) by class, with an immunoassay or thin-layer chromatography procedure. Results are presumptive because no confirmation is done. The false-positive rate for the screen is estimated to be 3% (i.e., of every 100 samples tested, three of them will have false-positive results for one of the drugs in the test group), whereas the false-negative rate for this screen is estimated to be low in the absence of adulterants. Thus, this test has a high true-negative rate. This test requires a random urine sample of at least 30 mL.

Drug Abuse Survey with confirmation
This is a urine test for the same drugs covered by the Drug Abuse Survey, but this assay uses gas chromatography—mass spectrometry (GC-MS) to confirm the results of the screening assay. This quantitative test is more accurate and sensitive and more expensive than the Drug Abuse Survey. The GC-MS may be used to test body fluids other than urine. This assay is recommended for employee screening programs or situations in which accuracy is paramount. Specimens should be collected under observation for greater reliability. Some states require that specimens collected for employee screening or forensic purposes be accompanied by documentation showing the chain of custody for each specimen. Substitute urine samples may produce false-negative results, and laboratory mix-ups can produce false-positive results. The GC-MS is considered the standard for testing for drug abuse and has a virtual 0% false-positive rate.
