Legal Implications of Section 328 IPC
The charges are serious, and the punishment is 10 years of imprisonment and a fine as per Section 328 of the Indian Penal Code (IPC).
According to Section 328 of the IPC, whoever administers to or causes to be taken by any person any poison or any stupefying, intoxicating, or unwholesome drug, or other thing with the intent to cause harm to such person, or with the intent to commit or facilitate the commission of an offense or knowing it to be likely that he will thereby cause hurt, shall be punished with imprisonment of either description for a term which may extend to ten years and shall also be liable to a fine.
Abetment Under Section 110 IPC
Probably, you are charged with abetment for it under Section 110, and the punishment is the same.
Though you have been informed of only a fine as the punishment, it appears there is an attempt to misguide you. If you accept the charges, the chances of it ending with a fine alone are not there. It is advisable to consult an advocate of standing in the local court before deciding on the course of action.
