Weed is over saturated market. Too many sellers can't get a profit or have to sell cheap.Anything that sells good on the road, is over saturated market and sellers are for forced to drop prices, cut their dope and pull scams towed up the losses.I'm betting something obscure would sell the best, nice and quietly too, so other sellers don't jump into market and start competing. Ya penicillin is a big seller. Junkies are always getting infected with dirty needles Ha ha. And too embarrassed to go to the hospital? Funny. Also STD's. need antibiotics and hiding it from the wife isnt easy. Hahjaahan
