From a moralistic and ethical perspective, nothing wrong with weed or alcohol. Consider how the ancient Greeks loved wine, Bacchus and Dionysus the god of alcohol and the grape, and also how alcohol in small doses is probably good for us (hormesis). Weed is good for pain medication, and the “hangover”of smoking weed is far better than an alcohol hangover. Yet this is my critique:

1. Weed makes a lot of kids lazy and kills their ambition. The normalization of smoking weed in poor neighborhoods kills ambition for kids to leave the hood.
2. Alcoholism is normalized in modern society. Most people in modern society are essentially functional alcoholics. Nobody critiques alcohol, yet it kills sooooo many people a year (drunk drivers, alcohol overdose, etc).
