And similarly, the alcohol and tobacco industries. It's really never about morality.

It's because the people who want it will still vote for you if you keep it criminalized. But a significant number of the ones who want it to stay criminalized will totally write you off if you decriminalize it.
In the US, how motivated people are is usually even more important than how many of them there are. Combine that fact with the electoral college and gerrymandering, and there is a constant threat of minority rule.
EDIT: Private prisons. Can't believe I forgot about that. Everyone else who replied has got the main reason nailed.
To block an conviction of an impeached president or a constitutional amendment, only 34 senators (17 states) are needed. As of 2018, that was as little as 7.32% of the US population.

And some python to help once you have lines to summarize: sum(map(float, open('foo').readlines()))
Unless the Zetas have recently started moving into Wyoming, too, I'm guessing they're also the ones being least harmed by externalities from the war on drugs.
Can you tell me why it makes sense for so few people to dominate the wills of so many?
When the United States was formed and the compromise for 2 Senators per state and house representatives by population was agreed to, the largest state population was 11x the smallest state population. Today, California is 70x Wyoming. This has the effect that Senators from smaller states have way more power in today's world than they did in the 1800s. The ratios are unbalanced and need to be adjusted just like we adjust the apportionment of house representatives via the census every 10 years.
That was the original thinking, but the 17th amendment turned the Senate into just another House of Representatives, but one where each member has a longer term and a hugely outsized influence compared to the number of people they represent.
Follow the money. There are a lot of people making a lot of money off of private prisons, generally in red states.
Absinthe makes you crazy and criminal, provokes epilepsy and tuberculosis, and has killed thousands of French people. It makes a ferocious beast of man, a martyr of woman, and a degenerate of the infant, it disorganizes and ruins the family and menaces the future of the country.
