ELI5: How are high-profile, open marijuana users like Seth Rogen, Doug Benson etc. not pursued by police for breaking the law?

The police know that prosecuting users doesn't work. Most of the efforts of the DEA and police go towards drug dealers and smugglers. 

Also, using Marijuana is not against the law, posessing it is. Furthermore, saying "I used marijuana" is not sufficient cause for prosecution and arrest, especially for entertainers, who often make up stories to establish a character for the sake of their art.
