I highly doupt any dispensary would sell seeded weed.The whole scene came about so good sensimilla would be available to the sick.
Medical mj,is sensi=without seed,as when seed production starts in the plant the thc degrades,lowering the quality of the weed.
The seeds might be worth a crack if you have the ability,youll not have to buy ever again,bliss.
Seeded weed can be the norm on the streets in some countries,very cheap.In saying that in hot countries good sensi really knocks you out,some prefer the outdoor and dont mind picking the seeds out,for a milder buzz.Ive found it helped me acclimatise to the heat and my own herb knocked me out leaving me wanting to crash.
Not sure of your circumstances,do you grow?
I hope you get sorted with some dank soon.
peace.
