high-rent district. >> mason is serving nine months at theo lacey, convicted of an unusual shoplifting charge. >> caught stealing a flea collar and a pair of workout pants. >> you're here because you stole a flea collar and a pair of workout pants? >> yes. and i do have a dog. that day, i was actually out of my mind on methamphetamine. i'd been up for four days straight without sleep. i have no idea why i was even in that store. if there's anything that you could say is the devil's drug, methamphetamine fits that bill perfectly. it's a blessing i got caught stealing that stuff because i was praying to god to stop and i couldn't. so i guess this is his way of helping me stop. i can flex. >> inside jail, mason is an advocate for healthy living. >> my friends call me popeye
