People who spread false facts

How do you handle people telling you how bad these drugs are. I literally have a friend constantly sharing on their IG story false info about GLP1s. Today she shared the drug contains lizard venom that causes cancer, honestly I’ve never met someone more uneducated she claims exendin 4 is in it which causes cancer but a simple google search says that is not in zepbound ozempic etc.

I’m so fed up I don’t even advertise I take this but she knows and keeps doing low blows

This medication has done nothing but make my life better, I eat better and actually work out now, I hardly drink and I’ve lost 25 pounds I wish people wouldn’t try to always dull others sparkle
