Another in the endless mass shootings in USA - this time Denver

[Lauren Johnson]

After the massacre Holmes calmly told detectives he had taken 100mg of the prescription painkiller Vicodin, and identified himself as "The Joker". The same drug was found in the system of actor Heath Ledger when he died of an accidental overdose of prescription drugs in 2008. Ledger played The Joker in the previous Batman film The Dark Knight. Vicodin side-effects can include euphoria, paranoia and, in rare cases, hallucinations.

No wonder he was so zonked out.

Vicodin strengths come in 500mg, 660, and 750mg, the maximum dosage for this medication is 1-2 pills every 4-6 hours depending on severity of pain and that information changes with the max dosage allowable for the adult... which is not to exceed 1gram (1000mg)per dose/or 4 grams (4000)mg per day..

Or, maybe not.
