Way back to the time when I was even younger I saw a movie where the protag smokes and thaught that it would be cool to smoke cigarettes.
So i waited till a day where no one was home then took the tea powder in the kitchen and wrapped it in a newspaper.
It was the most bitter thing that I had ever tasted and i vomited my entire stomach after taking that puff.
I remember it floated and didn't go down at all so I opened the tap and collected the water in a bucket before I dumped it inside.
