Sure, "when they inject", but the rest of the time? Generally no, they are not. This is why people DO try, if unsuccessfully, to get off of their addictions -- you don't like waking up in an alley, you don't like how broke you are, you don't like how you feel when you come down from the high, you don't like how you're hurting your family.
Way back in the day there were usage limits on everyone's internet service. Nowadays, not so much. Inference won't be expensive forever.
I mean, just Devil's Advocate, but I could see this becoming an addiction crisis like none we've ever seen in the past. Only since it wouldn't be as public, no one would really be aware of it. (Assuming most people won't broadcast what they're doing in their homes during their waking hours.)
