A safe supply has a significant lower risk of overdose though. There is absolutely no consistency with potency even with the same dealer/suppliers. You either get a product that has been cut with inert additives to inflate the product supply or you have product that has been spiked with more potent analogs to achieve the same effect.

Without any consistency in potency users do not know how much they are actually administrating even if that dose appears like one they have previously safely done.
