The PROTECT Act specifically had provisions against even drawings of any kind, however those parts to my knowledge were ruled unconstitutional. On the other hand, there are various state laws against the material; I don't have a better source than Wikipedia at the moment, but:
>Currently, such depictions are in a legal grey area due to parts of the PROTECT Act being ruled unconstitutional on a federal level; however, laws regulating lolicon and shotacon differs between states; several states have laws that explicitly prohibit cartoon pornography and similar depictions (such as video games in the state of New Jersey), while others usually have only vague laws on such content; in some states, such as California, such depictions specifically do not fall under state child pornography laws,[70] while the state of Utah explicitly bans it.[71]
