On March 4, Britney Spears was arrested for driving under the influence after being observed swerving in and out of lanes. The 44-year-old pop star admitted to consuming multiple prescription drugs prior to driving, including 200mg of Lamictal, 40mg of Prozac, and 2.5mg of unprescribed Adderall. Police found an unprescribed bottle of Adderall in her purse and noted the presence of an empty wine glass in her vehicle. During the arrest, Spears claimed to have a high tolerance for alcohol, stating she could drink multiple bottles of wine without impairment. However, officers reported signs of intoxication, including red, watery eyes and slurred speech. Witnesses had alerted authorities about her erratic driving, which nearly caused accidents. Following the incident, Spears entered rehab on April 12 for substance abuse treatment and reportedly left after less than a month, feeling positive and excited for a fresh start.
