However, it’s worth mentioning again that the research on regular coffee is way more extensive than what’s available for decaf. Summary: Decaffeinated" coffees do in fact contain caffeine in many cases– some commercially available decaffeinated coffee products contain considerable levels. One study found that decaffeinated coffee contained 10mg of caffeine per cup, compared to approximately 85mg of caffeine per cup for regular coffee.  Detection in body fluids Some beverages combine alcohol with caffeine to create a caffeinated alcoholic drink. The stimulant effects of caffeine may mask the depressant effects of alcohol, potentially reducing the user's awareness of their level of intoxication. Such beverages have been the subject of bans due to safety concerns. In particular, the United States Food and Drug Administration has classified caffeine added to malt liquor beverages as an "unsafe food additive". Jamieson RW (2001).

Caffeine can delay or prevent sleep and improves task performance during sleep deprivation.  Shift workers who use caffeine make fewer mistakes that could result from drowsiness. Withdrawal can cause mild to clinically significant distress or impairment in daily functioning. The frequency at which this occurs is self-reported at 11%, but in lab tests only half of the people who report withdrawal actually experience it, casting doubt on many claims of dependence.  Mild physical dependence and withdrawal symptoms may occur upon abstinence, with greater than 100mg caffeine per day, although these symptoms last no longer than a day.  Some symptoms associated with psychological dependence may also occur during withdrawal.  The diagnostic criteria for caffeine withdrawal require a previous prolonged daily use of caffeine.  Following 24 hours of a marked reduction in consumption, a minimum of 3 of these signs or symptoms is required to meet withdrawal criteria: difficulty concentrating, depressed mood/ irritability, flu-like symptoms, headache, and fatigue.  Additionally, the signs and symptoms must disrupt important areas of functioning and are not associated with effects of another condition.
