In my opinion the most important reason why nonaddicts who are interested in opiates ignore our warnings or think they can handle them without becoming seriously addicted is because we describe how bad our situation is after a significant amount of time . We describe how bad his life can become but he still thinks like a sober person because he didn ' t go through that development of becoming addicted . Usually you don ' t try heroin for the first time and end up homeless , stealing things and doing crazy shit right on the next day . This behaviour evolves slowly and with every day the desperation grows . Therefore we are slowly over time more willing to do things we could ' ve never imagined before . When a nonaddict sees us describing the result of this development , often our own current situation , he sees a junky who had time to slowly go down this road . He ' s still genuinely convinced that he won ' t go that far because he hadn ' t got the time to pick up the same bad behaviour . So he will think he ' s able to handle the drug without becoming as bad addicted as the people telling him to be cautious are , just to start making small exceptions in the things he is willing to do in order to be able to score .
