Possible prison time

So after leaving Calafate I turned west and planned to cross over into Chile to get a few hikes in over there in a hightly recommended national park before getting on a cargo boat that takes people north. Unfortunately what I didn´t realize is that coca leaves which are legal in most of the other countries in south america are considered an illegal substance in Chile. I had been carrying a small bag since Bolivia and the crossing into Argentina had not been a problem. I ended up getting stopped and questioned about them and having to let my bus leave me at the border. At first I wasn´t too worried about it but when I was refused a minute outside to have a cigarette I realized I was being detained. Coca leaves even if chewed all day can only be compared to a mild caffeine buzz so I still I wasn´t too worried about it until the garbled voice coming over a cb giving instructions clearly reapeated the word ¨carcel¨ a few times (in spanish carcel means prison). The rest of the 4 hours I was detained in that room with 3 or 4 border officials weren´t so fun. After sweating it out for a while I ended up only having to sign a statement saying I was unaware of Chilean law and believed them to be more or less like those of surrounding countries and pay a fine of $220 for not declaring I was importing organic material. I hitchhiked into town, which was only about 20 minutes away, and payed the fine as quickly as I could in order to put the whole thing behind me. A fine is a hell of a lot better than a few days in a cell but at the time the $220 really hurt.
