The Acute Effects of Caffeinated Black Coffee on Cognition and Mood in Healthy Young and Older Adults
TLDR
Behavioural activity of coffee beyond its caffeine content is suggested, raising issues with the use of decaffeinated coffee as a placebo and highlighting the need for further research into its psychoactive effects.
Caffeine content of prepackaged national-brand and private-label carbonated beverages.
TLDR
Most store-brand carbonated beverages were found to contain less caffeine than their national-brand counterparts, indicating that consumers would benefit from the placement of caffeine values on food labels.
Caffeine , Stress and Salivary α − Amylase
TLDR
Findings provide evidence for acute sAA changes in response to caffeine and stress in habitual caffeine users and suggest that additional pharmacologic studies are needed to provide a clearer picture of sAA activity in responded to stress.
Caffeine administration does not alter salivary α-amylase activity in young male daily caffeine consumers
TLDR
It is demonstrated that caffeine administration does not affect sAA activity, at least in healthy young men who regularly consume caffeine, which supports recent findings that basal caffeine levels in habitual caffeine users are not associated with basal s AA activity and that daily caffeine intake and diurnal sAAactivity are not related.
The impact of prior coffee consumption on the subsequent ergogenic effect of anhydrous caffeine.

TLDR
Prior consumption of COF did not decrease the ergogenic effect of the subsequent ingestion of anhydrous CAF, and times to exhaustion were significantly greater for all trials with CAF versus placebo.
Effect of Coffee and Caffeine Ingestion on Resistance Exercise Performance
TLDR
Coffee and decaffeinated coffee plus caffeine have the ability to improve performance during a resistance exercise protocol, although possibly not over multiple bouts.
The Safety of Ingested Caffeine: A Comprehensive Review
TLDR
It is reported that, for healthy adults, caffeine Consumption is relatively safe, but that for some vulnerable populations, caffeine consumption could be harmful, including impairments in cardiovascular function, sleep, and substance use.
Neuropsychological Effects of Caffeine: Is Caffeine Addictive?
TLDR
The intention of this study was to analyze the neuropsychological effects of caffeine and try to assess in which respect caffeine could be considered a potential drug of addiction.
Caffeinated coffee enhances co-operative behavior in the Mixed Motive Game in healthy volunteers
TLDR
After caffeinated coffee, participants exhibited significantly higher blood pressure and allocated significantly fewer scores to themselves and sent significantly more sadness message during the Mixed Motive Game.
Subjective, behavioral, and physiological effects of acute caffeine in light, nondependent caffeine users
TLDR
It is confirmed that acute doses of caffeine, at levels typically found in a cup of coffee, produce stimulant-like subjective effects and enhance performance in light, nondependent caffeine users, supporting the idea that the drug has psychoactive effects even in the absence of withdrawal.

TLDR
With both cola and coffee at the commonly used doses, self-reported motivation to work was greater and drowsiness and laziness smaller with caffeinated than noncaffeinated beverages.

Reinforcing effects of caffeine in coffee and capsules.
TLDR
Two experiments providing the clearest demonstrations to date of the reinforcing effects of caffeine in capsules and in coffee were studied in volunteer subjects with histories of heavy coffee drinking.
Caffeine self-administration, withdrawal, and adverse effects among coffee drinkers.
TLDR
The results indicate that some coffee drinkers exhibit signs of a caffeine dependence, ie, they self-administer coffee for the effects of caffeine, have withdrawal symptoms on cessation, and experience adverse effects.

Intravenous caffeine in stimulant drug abusers: subjective reports and physiological effects.
TLDR
The mood effects but not the physiological effects of intravenous caffeine were similar to those previously observed with cocaine in studies using similar methods and subjects, andIntravenous caffeine administration may provide a useful model system for investigating factors relevant to the use and abuse of stimulant drugs.
Caffeine reinforcement demonstrated in a majority of moderate caffeine users
TLDR
This is the first study in a relatively uncontrolled outpatient context to demonstrate significant caffeine reinforcement in the majority of normal subjects and caffeine choice was replicable despite changes in capsule colors across blocks.

TLDR
The pharmaceutical properties of caffeine described in this report explain its use in drugs used as stimulants, pain relievers, diuretics, cold remedies, weight control products, bronchial and cardiac stimulants as well as in drugs for the treatment of acne and other skin disorders.
