Every addiction is mental i think?..
There is no concrete evidence of this at this time I believe. What addictions do is alter the brain and change it's natural structure for desires. Additionally a lot of people who are addicted to something tend to get diagnosed with a mental disease. There is surely a connection.
I agree with you coffee and tea both have a addictive drinks'
Tea is addictive? Strange.
Yea coffe is verry addictive i drink life 3-4 packs of coffee per day
You mean cups?
Caffeen has been proven to have some addictive qualities. However, anything you have on the daily could cause your body to feel like it NEEDS it, so going a day or two without it will cause some side affects like anxiety. Coffee just so happens to be one of the most popular, daily consumed items.
That does make sense indeed. These side affects are tolerable and are nothing compared to when you don't drink/smoke/do drugs in the same time period (assuming the same level of addiction).
