kel: as i recall, you can carry a small amount on you. buy it in the bar, then go back to your hotel and chill there...assuming you're in a hotel. if you're in a hostel, they typically have/had a place where you could partake without repercussions. maybe it's changed since i was over there, but at the time it was really easy to purchase whatever you wanted...hmm...interesting. and good luck.
