like i said theres alot of members of the coca family, with a broad range of alkaloid contents and growth conditions.
and the ratio you have, puts the dry leaf content at around 0.0033%. which would put it at some of the lowest alkaloid containing coca being grown.
and the reason it isnt grown in large patches all over is cuz Columbians dont like competition. if you dig deep enough online you can buy coca seeds there was a site called sacredplants i think that had some.
and being from florida you might not know this, but america actually has some fairly high hillocks located here and there.
and no it wouldnt be easy, but it wouldnt be any harder than keeping any tropical plant alive in a northern climate.
and id imagine that if the cops did arrest someone growing a field of coca in the U.S. i dont think they would issue a press release. i think they might wanna keep that under wraps.
as to poppies. hella easy to grow. easy to get high opiate content poppy seeds.
they are easy to identify. but as long as your not aiming for comercial production you can keep small patches. the latex is easy to collect, its insanely easy to process into smoking opium. and if you want to turn it into heroin. you can straight up go fuck yourself
