In the event that any agent or employee of a covered pharmacy or retail distributor reports to any law enforcement officer or agency any suspicious activity concerning a targeted methamphetamine precursor or other methamphetamine ingredient or ingredients, the agent or employee and the pharmacy or retail distributor itself are immune from civil liability based on allegations of defamation, libel, slander, false arrest, or malicious prosecution, or similar allegations, except in cases of willful or wanton misconduct. A covered pharmacy that uses the electronic sales tracking system in accordance with this Act is immune from civil liability for any act or omission committed in carrying out the duties required by this Section, unless the act or omission was due to deliberate or willful and wanton misconduct. A covered pharmacy is not liable for damages resulting from a data breach that was proximately caused by a failure on the part of the electronic sales tracking system.
