a confidential informant said i sold them drugs. can i get charged for that?

Drug cases can be complex. If the only evidence the police have against you is a statement from a confidential informant, then that is not enough to charge you.  If the informant is truly confidential then the police have no evidence against you.  The informant's hearsay statement  is not admissible in court unless the informant testifies; that will not happen if the informant is confidential. Usually the police will have done controlled buys, surveillance of the home and a search warrant before charges are brought.
