You’re wrong.
Check my post before your’s on page 5, a lot of ornamentals are just as strong as those grown for pharmaceutical use.
Queen’s Poppy, Lauren’s Grape, Hen’s and Chicks and also Gigantium/Gigantheium are all ornamentals that produce a decent amount of opium and morphine.
Also regular opium poppies you find growing wild will produce opium that on average contains 12% morphine.
It is possible to buy so called ‘pharmaceutical’ seeds.
I don’t know how true it is but apparently the British pharma’ seeds are originally from Tasmania and aren’t the high thebaine low morphine type.
I know a site that sells a few different British pharma seeds, I say different cause they got them from different regions.
I know Negrogesic said he grew British pharma poppies before and they were great.
Someone else mentioned seeds, the vast majority sold in shops aren’t washed or sterilised/ungrowable.
Though I’m talking about UK, European, Turkish and Indian seeds sold for food use.
