Alright..
So first let’s look at the impurities, Tropacocaine is a known active substance that even has a book somewhat written after it regarding synthesis (if it didn’t get you high Otto Snow wouldn’t have written about it.) It’s a stimulant but in my personal experience and opinion I believe it also has deliriant like effects as well. Here’s an article showing it’s an anticholinergic just like scopolamine, just 1000times weaker.
Benzoyltropine and tropacocaine are two contaminants of street-cocaine reported to have parasympatholytic activity. Because the mechanism underlying this activity is obscure, we investigated the effects of these compounds on several cholinergic processes: sodium-dependent choline uptake...

You think to yourself, 1000x is much weaker. Well when scopolamine can cause folks to trip at 2mg orally with a bioavailability of 2-7% it’s very realistic tropacocaine could induce some effect. Even more realistic when thinking in the context of combining with the cocaine.
In my experience, the other alkaloids give either a dissociated feel or if enough is used a delirium that one night culminated in me thinking I was being chased through the woods by a band of cops. I could hear their voices, see their flashlights, hear the dogs and ATVS. It was hell. This experience was the definition of anticholinergic delirium.
Methylecgondine is another common one, it’s also a pyrolysis byproduct when crack is smoked. I believe it creates more of the fiend that we often feel to use more. It would explain why crack is so much more reinforcing than IV cocaine, crack is very hard to put down.
If we look at DrugsData we see these impurities and others like benzoylecgonine (I’ve tried this one too, it’s very weak but still active) are fairly common.
It’s more often than not these impurities are present; tropacocaine usually 1-10%, methylecgonidine 1-20%, benzoylecgonine 5-25% on average from a quick scan of the first page.
Almost always with cocaine people want to blame the cuts added after the fact, when I believe sometimes the sketchiness or extra fiend comes from these impurities and byproducts.
