Welcome Joon93, glad you showed up.
A word of warning about South Korea's laws if you don't already know - penalties are VERY steep for even testing positive for drugs.
"Cannabis use, in all forms, is strictly forbidden in South Korea and you risk imprisonment and hefty fines if you are caught. Something else that is different – you do not have to be found in possession of it. Police have the right to search you anytime they choose and they will test your urine or hair follicles for the presence of THC. If it’s there – well….that’s it, you’re off to prison. The Korean DEA (Drug Enforcement Agency) have even been known to enter clubs and do hair follicle or urine tests on the spot to determine if you have any drugs in your system. If you do, no questions, no time, you’re done.
We have heard reports from one of our teachers that a fellow teacher of his was busted by the Korean police for marijuana. Apparently he had been teaching in Korea for six years and had a job at a university, which is the most coveted type of position. That gravy train has come to an end for him. No more 8 month working year for good pay. No more cheap Asian travel. No more good, cheap Korean food.
We cannot confirm it but we were told that he was sentenced...to twenty years. Yes…there may have been extenuating circumstances, it may have been from something more than just testing positive for THC but the fact remains that it is a risky endeavor to partake in cannabis use in South Korea."

If this is true I would consider moving to another country as that is too high of a price to pay for Herb.
Peace.
