Summary

This study looked at whether a THC-free hemp protein powder is safe for healthy adults aged 18 to 65 who don't use cannabis. For 30 days, 32 volunteers took 40 grams of the supplement daily. Researchers checked for THC breakdown products in urine and monitored blood tests for liver, kidney, and overall health. The goal was to see if the supplement caused any side effects or lab abnormalities.
