hard to tell, but you must never incriminate yourself by saying “you got them for friends” because that is supply. that said strength is lower so 10 or 20 might still eb classed as personal. certainly 5 or 6 is these days in the Suffolk Constabulary area.
since 2006 the laws was changed and there is a “presumption of intent to supply where a defendant is found to be in possession of a certain quantity of controlled drugs.” – but neither the Home Office nor the cops have given a transparent description of what this quantity is (even harsher countries like Malaysia do) – so I think its left entirely up to the discretion of the cops with the suspect having to use his or her own defence resources to argue otherwise..
unfortunately circumstances and circumstantial evidence now seem to play a big factor – I would expect if someone our age is busted with 50 or so pills and we have a lot of younger friends / associates in their teens and 20s it would almost invariably be suspected we were dealing 🙁
