Ah you were right, it's basically decriminalizing but not lol
The new guidelines do seem pretty clear: If you are a small time quiet “hobby grower” not involved in any form of supply – especially to children – and no other offences are involved the guidelines for Production/Cultivation are:
Lesser role ‘if own operation, solely for own use (considering reasonableness of account in all the circumstances)’, 9 plants (domestic operation with assumed yield of 40g per plant): the sentence you can expect is in the range of a discharge or possibly a medium level community order.
(LOL at the assumed 40g per plant but I'm not going to dispute it XD)
