Hamlin appeared on the Pardon My Take podcast earlier in the week and was asked if drivers take Adderall. When Hamlin said yes, the hosts asked him to put a number on how many. Hamlin said 70 percent.
He later clarified he was joking about the comment, but not before NASCAR issued a statement saying that anyone who tests positive for Adderall without having a prescription would be suspended per the NASCAR drug policy. AJ Allmendinger was suspended after testing positive for Adderall in 2012.
