I think it's not uncommon for recreational psychedelic users to have a disdain and aversion to actual junkies, if using the 1970s sense of the word, would literally mean heroin addicts. Big dividing line between the two sorts of drug users.

I cannot remember if he used 'junkie' or 'drogado' or other terms when referring to those actors that had been a dangerous nuisance in the filming process. Surely he was fuming and rightly, commonsensically contemptuous remembering the episodes (one almost killed him and left scars).

Whatever the drug, it is the exact opposite of what that work stands for. The "sleeping intoxicated bum" is the very beginning.
