Since the Dawn of Mankind (or at least the discovery of marijuana), people have wondered, "Can giving cannabis to a fish help them relax?" Well scientists have finally answered that question, but you might not like it.
Scientists in Lebanon recently published a study involving fish and marijuana. They gave Nile tilapia fish doses of cannabis oil to see if it would help them relax and grow faster. Since tilapia are often farmed in high qualities, they can often live in less than ideal environments with reduced water quality and increased disease compared to in the wild. So helping tilapia relax could be somewhat beneficial.
Unfortunately, it didn't really seem to work. Scientists said they saw no difference in behavior from the fish who were given cannabis versus those on the control diet. They also speculate that the fish may have built up a tolerance for the drug after getting daily doses over a few weeks.
When it came to growth, there were some positives. The fish who were given cannabis oil saw an increase in their metabolism. But since the scientists did not increase the food given to the stoner fish, instead of growing more, they simply produced more energy. They said it's possible that if the cannabis tilapia had been given more food, they would've grown more. But fish farmers are unlikely to adopt that approach because it would mean they'd spend more on food, so it doesn't really benefit anyone.
The study ended with quite a downer, saying, “Until further research yields different results, we do not believe fish should be given reefer.”
Sucks to be a fish.
