[Spoiler] How was Bob Arctor set up?
It is revealed in the end that the plan was for Bob to become addicted to Substance D to infiltrate New Path without his knowledge, but didn't he abuse Substance D willingly?
If Donna was selling Substance D to Arctor to get him hooked, isn't that illegal? Or, because this is a totalitarian future and war on Substance D, this is something that was a necessary aspect of the plan?
I also remember the scene in which all the members of the house were paranoid about a break-in. Donna came to the house and mentioned how he smoked a joint earlier, seen in the ashtray. How did that get there, if it would be against her job to use drugs? It's assumed she didn't actually smoke it, right?
