Datamanager Question

[Surviver]

Hello, I've created a custom Datamanager.

Now id like to Insert Post Data:
$gbe =& datamanager_init('dm', $vbulletin, ERRTYPE_ARRAY);
$dm->set('userid', $vbulletin->GPC['gbuser']);
$dm->set('posterid', $vbulletin->userinfo['userid']);
$dm->set('title', $vbulletin->GPC['subject']);
$dm->set('message', $vbulletin->GPC['message']);
$dm->set('disallowsmilies', $vbulletin->GPC['disablesmilies']);
$dm->set('dateline', TIMENOW);
$dm->set('entryusername', $username);
$dm->save();

Should I use $db->escape_string() because of SQL Inejektion Leak ?

Thank you very much !
