I agree.Many foods do give us some sort of rush.
I myself used to be a real coffee addict.A friend of mine once counted me having 30 cups of coffee one saturday.I cut back drastically when that was brought to my attention.Actually I quit out right but the shakes I got were just incredible,so I went back to the coffee and then started to cut down on it.
I remember some years ago when I was still in New Zealand some guys getting stoned on datura tea.They had been drinking beer and smashed the bottles.While they were stoned they were walking around over the broken glass not feeling it.By the time they were found one of the guys had bled to death.Thankfully the other two survived.
The police did not prosecute saying that datura was a common garden plant found throughout the country and therefore not illegal.When some people said that if you could get high on it,perhaps it should be made illegal.
The police response was that if you were going to ban everything that got you high then they would have to close down all the supermarkets.
Many meditation centers do not allow the drinking of coffee or of tea stating that it affects your meditation.
As I said before,at my temple this rule is not in place,however we are supposed to mindful in respect to food and drink.Only taking what is necessary and no more.
I personally have no more than 2 cups a day.Anymore and I think sitting meditation would be off the agenda.
And crawling on the planets face,some insects called the human race.
