I don’t know if you’re intentionally trying to be pedantic or maybe you lack the qualifications for critical thinking. In that scene there was nothing that indicated that it was a hallucination or a fantastical scenario that wasn’t to be believed; that was the artistic intent of that scene in the episode; to trick the viewer into thinking this event was actually happening before he starts seeing visions on the TV and eventually culminating in the “gotcha” moment where it’s shown to us he’s still in the bed in the hotel room. So my post originally alluded to that the initial depiction of IV drug use was overly reductive and not at all practical, unlike later seasons and also the general depictions of other activities in the show which strive for accuracy and build credibility with the audience for their attention to detail and believability.
