Supposedly ... cannabis was included in the Misuse of Drugs Act to try to stop or decrease the "misuse" of cannabis (as with other drugs listed) - that means the use other than as a medicine, although cannabis was also scheduled as a drug with no medicinal uses: that is all use is Misuse.
Now the scheduling and laws are being changed and cannabis, CBD, THC, will once again be recognised as a drug with medical uses.
However, cannabis will remain in the Misuse of Drugs Act, will still be classified as a drug with a potential for "misuse", that is when used "recreationally" or "religiously".
People will be arrested for growing their own (unless of course, as some people want, some people will be permitted to grow their own with doctor's permission or special exemptions.
People may still be arrested for possession without prescription.
But those in medical need, with their doctor's agreement (if they can get it) will be prescribed cannabis and cannabinoids produced by pharmaceutical companies, and their pains reduced, which of course is good.
But the false distinction between users and the matter of their Rights and Freedoms, is still being ignored.
Otherwise law-abiding people that choose to produce and possess, use, share, cannabis even in the privacy of their own homes, may still be open to ATTACK by tyrants and prohibitionists that want to ignore their Rights.
That is the majority of UK cannabis consumers and those unable to get prescriptions.
The "we want medical cannabis", playing into the hands of pharmaceutical profiteers, are taking is back to that false distinction that gives the wrong impression that the law is about drugs, when in fact it is about people, and largely ignoring the issue of Human Rights laws, which are higher laws that are meant to stop tyrannical laws such as the Misuse of Drugs Act.
