Well, once you get hooked on amphetamines, the addiction actually makes it impossible to do work without taking a dose. It’s a problem that builds and builds, so don’t be surprised if those people simply have high tolerance to their medication now and are fully dependent. To your point, speed can help you do Leetcode for sure (it’s speed after all). Is it worth it? Yes, since the money involved is significant. But it is also a drug, and if you get addicted, you will have a life long problem (especially when you need higher and higher dose to get the same effect, and when you’ve forgotten basic discipline and work ethic without the help of the drug). I will not mention the insane side effects around insomnia and paranoia. Dependence will also act as jet fuel to any type of imposter syndrome you have (you will feel vulnerable without it, and question the validity of your success, reality will be a never-ending existential crisis). But hey, a 40 dollar script could get you a 200k salary, so who is anyone to judge. I just wanted to throw the counter argument out there to the casual uptake of amphetamines. But I will add(pun?) this, you will be at a disadvantage against those that use this drug to make it in tech (or medical). It’s basically our steroids, and being a clean athlete will be harder.
