You're participating in a clinical trial study for a new drug. All you have to do is take a pill and answer some questions, but you're experiencing some side effects! Players in (May Cause) Side Effects compete in teams. One player is the test subject, acting out side effects while getting their partner, the lab assistant, to guess a word or phrase. If they guess right, keep the card, and stay in the drug study! Whichever team has communicated the best at the end of the game wins! —description from the designer
