Four Thunderbird High School 
                  students became ill in their classrooms Thursday afternoon 
                  after downing anti-psychotic pills during lunch.
One 
                  student was semiconscious and another was combative after 
                  taking the pills at a fast-food restaurant known as a popular 
                  hangout for students near the 19th Avenue and Thunderbird Road 
                  campus. 
Four boys - three sophomores and a junior - 
                  were taken to local hospitals. Eleven other students who also 
                  may have taken the pills were evaluated on campus by 
                  firefighters. All of the students were expected to 
                  recover.
Firefighters were called at 12:20 p.m. after 
                  one student passed out at his desk and did not respond when a 
                  teacher tried to rouse him, Phoenix police Detective Tony 
                  Morales said. Another student went into convulsions.
                  
Other students were 
                  lethargic, weak and weren't responding appropriately to 
                  questions from paramedics, Assistant Phoenix Fire Chief Bob 
                  Khan said. Division Chief Joe Ducote said the students 
                  admitted taking the pills.
"It doesn't surprise me 
                  because kids try new things," said Ashley Margerum, 15, who 
                  knows the students involved but attends a nearby charter high 
                  school. "There are a lot of drugs in schools." 
The 
                  teenagers may have gotten the pills from a former student, 
                  Morales said. The pills are being analyzed.
Police said 
                  the pills were Zyprexa, which is approved for the treatment of 
                  schizophrenia and acute mania associated with bipolar 
                  disorder. The 20-milligram tablet is pink and 
                  oval-shaped.
Zyprexa has been prescribed to more than 
                  11 million people in 84 countries since it was approved in 
                  1996, according to a Web site about the drug. Side effects can 
                  include drowsiness, dizziness, weakness and mild 
                  trembling.
Lt. Joe Kemp said officers have seen 
                  drug-related incidents "off and on at all those different high 
                  schools, but nothing of this magnitude."
"High school 
                  kids are in that age group where they're experimenting with 
                  things," said Phoenix police Sgt. Becky Mann, who supervises 
                  school resource officers in the Squaw Peak precinct. "They 
                  want to try new things. They're rebelling against their 
                  parents, and they want to please their friends. A lot of good 
                  kids get in the middle of it."
Mann said the most 
                  common drug on high school campuses is marijuana because it's 
                  cheap and easy to buy and sell. Kids across the spectrum also 
                  are experimenting with methamphetamine, and Ecstasy is still 
                  popular, as well. 
                  
Kids sell their drugs
In addition, Mann said 
                  officers on campus see students bringing anti-depressants, 
                  painkillers and other prescription drugs to campus to 
                  sell.
Sometimes Mann said, students won't tell their 
                  peers what the drug actually is, only that "it'll make you 
                  feel better." Students even try to sell medications that have 
                  been prescribed for them.
"A lot of kids are on 
                  anti-depressants," Mann said. "They refuse to take it, and 
                  they get rid of it to make money.
"They get a lot of 
                  money for them at high school." 
The majority of high 
                  school campuses in Phoenix have officers assigned to them, 
                  teaching students about the dangers of gangs, drugs, alcohol, 
                  tobacco and even bullying.
"There's some kids that 
                  really need direction," Mann said. "They want 
                  direction."
                  
Incident 'under control'
Carole Sabo, a 
                  spokeswoman for the Glendale Union High School District, said 
                  school officials are investigating the incident at Thunderbird 
                  High School, but it "is under control." Although the school is 
                  in north Phoenix, it is in the Glendale district.
On 
                  Thursday, a classroom at the high school served as a triage 
                  area to treat the boys and girls, mostly freshmen and 
                  sophomores, who were involved, Ducote said.
Two 
                  students were sent to John C. Lincoln Hospital-North Mountain 
                  at 1 p.m., and two others went to Banner Thunderbird Medical 
                  Center shortly after. Parents were notified and arrived to 
                  pick up the others.
Students who were not involved in 
                  the incident were kept in their classrooms, and classes then 
                  resumed. 
After classes ended, students milled around 
                  outside the school gates. Most had heard about the drugs but 
                  knew little more.
Bruce Balls, a junior, shrugged and 
                  said he wasn't surprised to hear about the drug 
                  incident.
"It's pretty rich and a public high school," 
                  he said.
