I miss the times before 1992... You know in Greece it was legal to grow weed for seed and fiber but with a special state license that was very difficult to obtain, between 1949 and 1992.
Setting aside the license part and the fiber products, you could go to either the state monopoly agency or any supermarket and buy cannabis seeds to feed your birds (many people keep them as pets) freely with no suspicion or implications. The same happens today, but what was important back then was that a great proportion of the seeds was not from hemp but from very potent sativa and indica landraces.
The law back then had no limitations on cannabinoid percentage and many seeds were from confiscated illegal drug plantations or it was the licensed growers themselves using the landraces for their crops.
With a few trials you could find a super potent strain, plus feral cannabis plants were quite widespread in the countryside and you could just go for a walk, find some, pick and try. So back then birdseed was not so "innocent" as it is today. Note that back then it was not possible to purchase freely from seedbanks.
However in 1992 the cultivation was totally criminalised and prohibited. That was a result of the terms in the Maastricht Treaty. Genetically engineering or selective breeding of specific stable low potency strains was at its beginnings and the state was anticipating the EU guidelines that would regulate this market. It took 20+ years and they finally adopted the legislation to the EU directives with only the crap genetics like finola being legal.
The problem with this is that a great wealth of genetics was lost since 1992, and many landraces are currently extinct. The few people that kept seeds from that period were very wise and very lucky, but since landraces are not really commercially viable and productive, most people just keep their seeds in a drawer...
So I miss the biodiversity of that time. Well nowadays things are much easier and convenient, but we cannot get these smokes any more...
