ELI5: Why was the prohibition of alohol overturned in 13 years while marijuana hasn't been in 45 years?

It's because more adults had been experienced with alcohol and the propaganda campaign was not as successful. People simply didn't believe the (mostly religious) bullshit. 

But we have a lot of people in the US today that still believe all the propaganda and hokey pseudo-science the government spewed on them during the 20th century. And marijuana prohibition has been going on for way longer than 45 years.
