Whenever someone does something stupid, like crash a car, get in a bar fight, or, say, stab someone 123 times, they are always looking for an excuse. Somewhere to lay the blame. After all, they couldn’t have done anything like that, so it must’ve been some outside person, or situation, or invisible force, or even a miasma. Perhaps alcohol or drugs. Maybe even cough medicine. Really? I don’t buy it.
That’s apparently the defense of one Matthew James Phelps, a young pastor in North Carolina, who apparently inflicted 123 knife wounds on his wife. He stated that a dose of Coricidin Cough and Cold medicine made him do it. Or as he said: “I know it can make you feel good and sometimes I can’t sleep at night.” Too bad he didn’t simply go to sleep.
No doubt various drugs can cause anger, aggression, and even psychosis in some people. Cocaine has done it, and Phencyclidine (PCP or Angel Dust) was notorious for it. Meth, too. There are others, but I don’t think Coricidin would be a likely member of that group.
Possible? Maybe. Likely? No.
