ELI5: How are drugs made cheaper by 'cutting' with something that can be even more powerful than the original drug?
gpt
lol, this is a fun ELI5

Let's say you have lemonade that costs you $.50 and you sell it for a dollar. You'll make $.50 profit.

If you add more water it only costs your $.25 so you make an extra $.75. But your customers will notice your lemonade isn't as good.

So you buy a $.10 sour candy and add that to the lemonade with the extra water. It costs you $.35 to make, but you still sell it for a dollar and customers don't notice the difference and you make $.65.

lol... replace lemonade with heroin and sour candy with fentanyl.

edit: cost wise fentanyl is smaller and cheaper than heroin, but it's not used for recreation. So you're kind of "faking" heroin by using it.
