According to research, while drinking coffee can affect the same parts of the brain as cocaine, it does so in completely different ways and is nowhere near as pronounced.
Drinking coffee is a self-reinforced behaviour, rather than an addiction. Coffee does not fit the profile of addiction - it does not cause harm to the individual or society and drinkers aren't compelled to drink it.
While there's evidence for coffee withdrawal symptoms such as headache and lethargy, the symptoms are easily and reliably reversed by drinking coffee and some people will never develop a tolerance or withdrawal symptoms.
At the end of the day, moderate intake of coffee is relatively safe for most people and may even increase your well-being. Have it black with a square of smooth dark chocolate for an extra taste bud pleasure hit.
