They do exist.. just be very hard to find.
I remember a trip to S. Korea about 2 decades ago, was a 3 month trip and I kept pestering a friend there to hook me up with some weed cos I obviously havnt had any for almost 3 months lol.
One night towards the end of my stay there that friend took me to a night club and we went into a vip room out the back. What I then witnessed had me in stiches for days... we walked into a bunch of Korean gangsters sitting around a table that had a heap of pot seeds plucked from buds from a recent harvest.
Fuck me they were plucking the resin coated pod covering the seeds from a recent harvest for smoko!!
After a bit of a chat the boys offered me a joint which I refused and said I needed a bong, so after quickly putting together a plastic bottle bong in like a minute to which they were absolutely amazed by I smoked a cone of these seed pods from a mysterious Korean strain. Five mins later phuck me, I was plastered lol, was an absolute trip being ripped in korea and had a ball that night!
So yeah have a sniff around some clubs lol!
