You know, if they legalised cannabis for all adults, there would be no need to campaign for medical access. depend on ailment and the doctor's opinions (now all doctors in The Netherlands will prescribe Bedrocan cannabis and when they do, it costs more than from the coffeeshop and choice is limited). So we would still have to campaign for everyone else.
What about the children?
Well they would not of course be able to buy if they are not old enough assuming an age restriction, but parents can buy for the older teenagers just as they can legally buy and supply alcohol for them. (the child's age after which parents can legally supply alcohol tothem is 5)
As for medicine for the young - just like other medicines that will be possible of prescription from a doctor.
Once outlets for adults and home growing are legalised, pharmacies and health / herb shops will also be able to supply.

If we all joined together and campaign for everyone, I think we would make more progress over the next few years.
Of course some people will pessimistically speculate "the government won't do that" - well they certainly won't for much longer if people do not unite and put on the pressure!!
