I read this book “Methland», about the use of the drug in the deindustrialized Midwest. A lot of the people who used it did it to be able to work long shifts (they had to work a lot, because the hourly wages were so low). That may be the case for North Korea as well. If you have to toil long hours in the field without proper nourishment then meth will of course look like a good deal.
Damn, whatever happened to Red Bull?
Meth's probably cheaper.
Seriously? How much does meth cost?
Not all that much, and to get a buzz from Red Bull, you'd need to consume more than one can of that piece of marketing hype. If you're using meth not to get high but as a stimulant, the dosage seems to be around 10mg so as the price Kitteh is quoting, about $1/dose which is cheaper than a can of Red Bull. And that's in the US. In North Korea, meth is probably cheaper and Red Bull is more expensive.
Now clearly, because of tolerance issues, meth dosing is not likely stay at 10mg, even if you're only taking it as a stim rather than as a buzz.
