Because your choice now is either I use my own needle now, or I could share a needle now and get a disease that's going to possibly kill me 10 years from now, or I could use my own needle now and go to jail tomorrow.
Zato što je sada vaš izbor ili koristiti svoju vlastitu iglu sada, ili dijeliti iglu sada i dobiti bolest koja će me možda ubiti za 10 godina, ili mogu koristiti svoju iglu sada i otići u zatvor sutra.
