Data collection was performed in the District of Jatinangor, Sumedang Regency by using the purposive sampling method. Six respondents were selected. Data were collected through in-depth interview techniques and were analyzed using content analysis technique.Results: There were 3 main responses regarding the respondentâs opinions. First, respondents showed several attitudes toward drugs in general and also several attitudes toward porcine-contained drugs. Respondents showed concern for the medications used and wished either to be informed or not about the prohibited substance in the drugs.
