Is there not a danger here of making much out of comparatively little? If Julie is now to be a big time dealer, I guess it would make Jeremy a big time supplier? Were the house sharers' recreational habits not curtailed because two of their number hoped to get into the military?......................conversely, I have no doubt that police used various tricks of their trade to extract information from those they believed could help with their enquiries, even if those enquiries could only be peripherally linked to the murders.
Big time, little time, either way it is breaking the law with the potential for a fine and/or custodial sentence as follows:

I believe EP used this sort of tactic against these middle class people ie 'drugs were found in your home and this will certainly put an end to your hopes of a career in the military/teaching profession'.
It appears EP were well aware JB was growing cannabis at his cottage and distributing via the likes of JM and his mail order business. Why not pursue him over this when he was pursued over OCP and we know EP adopted a heavy handed approach over drugs as evidenced by the way they handled MM over drugs.
The argument EP were interested in the murders not a 'piddly bit of weed' doesn't stand up given JB was charged over OCP.
The argument EP adopted a soft touch with cannabis doesn't stand up given how heavy handed they were with MM and CB.
