I am sorry to hear of the tragedy that you and your family suffered, however please don’t take Amazon’s actions as an accusation or as a personal attack.
Amazon and yourself have the same goal it would appear, to reduce the amount of drug use, so you should be pleased that when a product is suspected [correctly or incorrectly] of containing a prohibited drug then Amazon’s first reaction is to pull that item from sale.
If you are able to persuade Amazon that your bundle of items is safe and contains nothing that is prohibited then your listing will be reinstated and the defect removed. [I say “if” because it may be difficult to persuade a somewhat intractable organization that black is black and not just a darker shade of grey, in other words despite anything you show them they may still say “but it’s prohibited”]
But good luck.
