This is the most addictive shit ever

I don’t do cocaine too often because of its price tag, but oh boy, when I get my bag nothing in the world matters more than snorting the next line. I have baught larger quantities, even up to 7gs, with the intention of using throughout a few weeks or at least one week minimum. But every fucking time I can’t stop using until the bag is empty. I’ll go through my entire supply in a 48 hours binge and waste an expensive high. There’s always a point where getting high isn’t possible anymore in the same sitting without a night of sleep. I know this well and always plan on saving more for the next morning, knowing I’ll get a good initial rush with replenished dopamine. But no matter what, even though I’m wasting precious blow for no high at all, I cannot stop this obsession with hitting another line until it’s all gone. I hate how this happens and I feel like I missing out on actually being able to enjoy cocaine. I can enjoy it for a few hours until it’s no longer fun and just a fiend trap. When the coke high isn’t even that good anymore, why can’t I stop? I’ve had much better overall euphoria from meth binges or even Adderall, but coke just becomes an insatiable beast growing inside me that eats me from the inside out. Is there a specific neurological explanation for why cocaine is so addictive?
