Revolutionary_Song16 seems to have blocked me because I can no longer reply to them but I wanted to share some sources for you.
According to the 2019 NSDUH, 47.1 percent of adults ages 18 to 22 drank alcohol in the past month.
At 22%, 18- to 29-year-olds are the most likely age group to smoke marijuana
And that's just the people who do it legally.
I'm sure tons of people are just ordering cause they're lazy. But you seem to just be ignoring very large parts of the population.
