One thing stands out that makes me believe the harsh reactions referenced by the author are probably justified. He is clearly addicted to cannabis (9% of people who use cannabis become addicted (2015)), which affects judgment, as well as a whole slew of negative effects on brain chemistry that impairs thinking. The behaviors described are textbook examples. That's a tragedy. Sounds like it might have been a great movie, the kind of movie Hollywood no longer seems capable of making.
