A old coworker boasted about abuse of stimulants and actively conversed with folks publicly about strategies to get your doctor to prescribe an increased dosage. He was also very arrogant, pumped out features like no tomorrow but the code was always just barely functioning. Product loved him because he delivered but he left a wake of destruction for the security team to clean up. Another person I worked with said he would never hire or work with someone who uses nicotine. It was even suggested that nicotine users "deserve" to be sabotaged and should not be employed.
