This is the most obvious and most widely acceptable form of self-medication practiced today. With the popularity of coffee culture being at its apex, being habitually medically stoned from coffee is the now the norm for millions. For example, a “grande” cup of Starbucks coffee (16 oz) delivers 330 mg of caffeine, and technically, caffeine intoxication begins at around 260 mg. Potentially dangerous caffeine intoxication happens around 500 mg (depending on your weight and tolerance) and can produce hallucinations, paranoia, convulsions, confusion, and diarrhea. If anything, this would not be a high anyone would want to take to the extreme.
