Is it locked to receive your own lettuce opium from delirious lactuca serriola?
Answer: strongly doubt it unless you know a lot around chemistry and have the proper lab equipment.
Yes. Although if you want "true" lettuce opium, sort sure it's Lactuca virosa, not Lactuca serriola. Make sure you're keen on the proper extraction technique, equipment, etc., and you'll be fine. i do it all the time. affix some paprika for zing.
no
