4. South Korea
If you have THC in your system while in South Korea, you could be in deep shit. The presence of THC in urine or hair is enough to put you behind bars for at least a few months. If you’re a Korean citizen, you can be jailed and fined for smoking even while you’re outside the country. Crown J, a Korean rapper, received eight months in prison plus fines for lighting up in the US. This, believe it or not, is completely backward to North Korea, the military, dictator run state has NO RULES regarding marijuana.
