| - | Hollywood funnyman (and success story) Seth Rogen is known for many things, not the least of which is his penchant for smoking marijuana. | + | Hatched in quiet streams and rivers, salmon undertake a perilous journey to reach the open ocean where they become mature adults. Over millions of years, generations of young salmon have migrated great distances, in some cases traveling hundreds of miles from freshwater systems to the sea. However, modern salmon face a hurdle that was unknown to their ancient ancestors: pharmaceutical pollution that changes their migration behavior. |
| - | In a new interview with The Guardian published on Saturday, Rogen – who runs a weed business in addition to his writing, producing, directing and acting pursuits – acknowledged his ability to intake marijuana with ease may make him something of an outlier. | + | Recently, researchers discovered that when a drug called clobazam accumulates in salmon’s brains, migrating fish reach the ocean sooner and navigate dam obstacles faster. On the surface, this change might seem helpful to salmon. However, any deviation from normal animal behavior through human activity — particularly when psychoactive substances are involved — is a red flag, and the full extent of how drug pollution may alter salmon health, behavior and reproduction is still unknown, scientists reported April 10 in the journal Science. |
| + | Clobazam, which is commonly found in wastewater, belongs to a group of medicines called benzodiazepines, which depress the central nervous system. The drug is used to prevent epileptic seizures, for short-term treatment of anxiety and to treat anxiety-related sleep disorders. But because neural wiring in fish resembles that of mammals, fish are highly susceptible to the effects of drugs that tweak human neurochemistry, said Dr. Christopher C. Caudill, a professor in the department of fish and wildlife sciences at the University of Idaho. | ||
| - | While Rogen admitted “some strains” do put him “to sleep,” he said the type of marijuana he uses daily does not negatively affect his productivity. | + | “Humans share a large amount of biological architecture with fishes — our physiology and anatomy are remarkably similar. Thus, it is intuitive that psychoactive drugs alter the behavior of both fishes and humans,” Caudill, who was not involved in the research, told CNN in an email. |
| - | “For sure I process it differently than other people do,” the “Pineapple Express” star added. “I’ve been at parties with people and we’ll share a joint, and I’ll be fine and go about my day, and they’ll enter, like, a new dark period for three months. Years will go by and then I’ll run into them at a party and they’ll be, like, ‘The last time I saw you was the last time I smoked weed, and it was terrible.’” | + | Prior research showed that benzodiazepines could alter behavior in Atlantic salmon (Salmo salar), but they did so under conditions unlike those experienced by wild salmon, said study coauthor Dr. Marcus Michelangeli, a lecturer in the School of Environment and Science at Griffith University in Queensland, Australia. |
| - | “I’m not physically gifted in many ways, but there’s one way in which I am, which is in my ability to process weed,” Rogen continued. “And to me it’s a very therapeutic part of my day to day journey which I don’t even question or think about any more, honestly.” | + | “Those studies were largely conducted in laboratory settings, only tracked movement over short distances — less than 100 metres (328 feet) — or used drug concentrations much higher than what salmon would typically encounter in the wild,” Michelangeli said via email. |
| - | When presented with the suggestion that he should leave his body to science, he replied, “Oh, I will.” | + | “Our study took a different approach. We followed the entire river-to-sea migration of juvenile salmon in a natural river system, using drug concentrations that match what fish are actually exposed to in the environment.” |

| + | The field investigation’s findings highlight the growing risks pharmaceutical pollutants pose to wildlife populations across the globe, according to Michelangeli. | ||
