Not sure if this has already posted. Mixes in the issues of the negatives for youth using marijuana along with the pressures of the costs of college and the impact of more complex mortgage products. I kind of wish the author had tied the three issues together way more gracefully, but whatever. But for the marijuana issue, basically a few arguments we've all seen: "There are many excellent reasons to avoid marijuana. Marijuana use damages brain development in young people. Heavy users become socially isolated and perform worse in school and at work. Marijuana smoke harms the lungs. A growing body of evidence suggests that marijuana can trigger psychotic symptoms that otherwise would have remained latent." "Marijuana use is too risky a choice"
