it is illegal to cultivate members of the genus cannibis in the uk, rarely plants in the same family can form hybrids (hybrids will only be able to be multiplyed with cloning) hybrids formed from plants of 2 different genus belong to neither genus and have a new genus and species name specifically for the new genetics, a hybrid of a cannabis and another outer genus plant (possibly still producing the same cannabinoids as cannabis) would belong to a different species therefore would be a legal plant to cultivate (for a short while untill it would be criminalised), it would be legal and still produce cannabinoids, does this seem logical?
