This is pretty funny: https://www.complex.com/life/20-year-old-heart-attack-trying-dry-scooping-tiktok-challenge/ The whole Tide pod challenge was fake, but it appears people are really doing this challenge where you consume a dry scoop of pre-workout.
 
Pre-workout is basically a stimulant blend. They'll have as much caffeine as 3-4 cups of coffee and a bunch of other ingredients with stimulant effects. I've taken pre-workout a couple of times prior to going to the gym (according to the directions on the bottle, i.e. only trying a little bit and mixing it with a lot of water). It made me super jittery (and I'm not caffeine sensitive, either), so I don't use them at all.

What ever happened to stimulant-inclined people just doing a little cocaine? It's probably better for you.

Than that?
I would say so ...

Yep for a while I was getting pure caffeine in little bottles. 10-12 drops in 8oz of water was really bitter but like drinking a full pot of strong coffee in one drink. I can see how that could cause a heart attack, If I hadn't been as young and fit as I was I could have had a problem. 

Caffeine and nicotine are 1 atom off ...
Nicotine is one of the most deadly substances we could possibly ingest ...
(IE: 1-2 of those drops would kill the average man)

Think about that ...

Yeah I think I did more damage with that shit than with all the "illegal" drugs I've done put together.

Most do ...
They smoke more than they do most other things ...
... and often while doing those other things ...

One of my buddies grew up in Pakistan borderlands while his dad fought against the Soviets in Afghanistan. He used to have a CIA manual where they had instructions for extracting & processing the nicotine out of cigarettes & using it to kill people.

Yeah, you can do it with chewing tobacco ...
1-2 drops and they are no longer with us ...

I've heard stories of babies dying from chewing on cigarette butts. Can't confirm that they are real though. If the one-two drops mentioned for an adult is accurate then I can see this happening. An ashtray full of butts might seem pretty interesting. Lots of kids eat burnt matches.

Yeah, it's a highly concentrated toxin ...
