Indeed. Back in the 1980s I once spent the winter months at Goa, staying in a small house with 3 rooms, literally only 100 metres from the beach. The other two rooms were occupied by English junkies, brown sugar was their cup of tea, and every day after breakfast they would indulge in their nasty habit, and then spend the entire day lying on their iron beds with thin mattresses, in the semi darkness. At dusk they would come out for a little recreation playing gentle frisbee. One of the guys was quite strong physically but his friend, an ex-Radio 1 sound engineer who had given up his job to come to Goa where the heroin was so much cheaper than the UK, had a weak constitution and would frequently throw up, a sound that resonated through the house where the walls didn't reach the ceiling. It was exasperating to see them wasting their lives, here we were in brilliant blue sunshine, surrounded by beautiful girls from around the world, swimming, playing beach volleyball, etc, and these two spent the entire time lying on their beds in a darkened room, staring at the ceiling! For these two Italians, going cold turkey in cells in a Samui jail will not be fun, but if they've run out of junkie friends or money outside perhaps it will cure them of their addiction.
