This is slanderous !
What 1st hand evidence do you have or would legally be able to share that any person is addicted to any substance?
Is it 5th 6th 7th hand info that someone may have said off the cuff that you have picked up like a hot potato and wrapped it cold hard lies ?
You saw this?
You know this?
You overheard this?
You assume this?
Which is it?
