Clemson star Sammy Watkins was arrested early Friday morning on drug charges. University police stopped Watkins' car and found marijuana and two pills, Adderall and Vyvanse, for which Watkins did not have a prescription. The pills were commonly used to treat ADHD. Watkins was held by city police. Both chargers are misdemeanors and Watkins was released on a $1,620 bond Friday.
