Everything is speculations as of now. So many wild theories and conspiracies going around, so it's better to wait and watch. Maybe after Bihar elections everything will be clear where this investigation is going.
The NCB knows the list of apparently 25 or something Bollywood druggies. 3 of them have already been named in the news yesterday, so you can expect the remaining to come out very soon. Probably the people you mentioned are drug addicts, probably they aren't, we sitting on this forum can't guarantee about this.
Besides, it's not necessary that all the drug addicts in Bollywood are named by her. It's possible that there are other actors who indulge in drugs, but have another dealer or whatever. So just wait around for sometime, everything will be clear soon.
