NASCAR on Saturday morning will host a mandatory meeting with its teams at Dover International Speedway, which multiple industry sources say will lay out the sanctioning body's new drug policy.
The new policy, sources said, will include random testing for drivers, over-the-wall crew members and NASCAR officials.
Those same industry sources said NASCAR would not implement any specific list of banned substances, claiming they, as a sanctioning body, want to be as strict as possible with this new plan and that any substance can be abused.
NASCAR's former drug policy, which tested only under "reasonable suspicion" of abuse, came under fire in May after former Truck Series driver Aaron Fike told ESPN The Magazine's Ryan McGee that he had raced while high on heroin.
Following Fike's admission, NASCAR spokesman Jim Hunter told ESPN.com that chairman Brian France had appointed a group of company officials to an interim committee that would study the policy and whether it should be revamped.
NASCAR officials, reached by phone Friday, chose not to comment.
