You can check if string contains a word with method contains().
if(myString.contains("drugs"))
If you need only URLs containing /drug/ try to do something like this:

    Pattern p = Pattern.compile("/drug(/|$)");
    Matcher m = p.matcher(myURLString);
    if(m.find())
    {
        something_to_do
    }

(/|$) means that after /drug can be only a slash ( / ) or nothing at all (dollar means end of the line).So this regex will find all if your string is like .../drug/... or .../drug

Use split() as such:

final String[] words = input.replaceFirst("https?://", "").split("/+");
for (final String word: words)
    if ("whatyouwant".equals(word))
       //do what is necessary since the word matches

If your code is called very often, you may want to make Patterns out of https?:// and /+ and use Matchers.
