How can a wimpy man get killed in Santa Barbara County Jail?

My friend is a male (age 30 but looks age 22), very weak, 5 ft 6, white, wimpy/weak, 195 pounds (overweight due to side effects of psych med), takes 5 psych meds (not dangerous or bipolar), has Asperger Syndrome, mild Tourette's, ADD, severe treatment-resistant depression, OCD, SEVERE anxiety, takes 4 asthma meds per day, vegetarian, take 800 mg/day Seroquel, clonazepam, 10 mg/day Adderall XR, 400 mg/day Topamax, Lexapro 60 mg, Serevent, Flovent, Xopenex, Singulair. Will he get ALL his meds? If falsely accused by his mom and sister of criminal threats, he will likely get jail time (cannot do community service). Will he get d/killed by inmates? Or will he be able to simply forgo his meds, get seizures/withdrawal and die? (No history of drug abuse--always compliant with meds).
