Lorcet, lortab, vicodan are hydrocodone. It's usually 5, 7.5, or 10 mg hydro and 500 or 650 aceteminophen(tylenol). NEVER EVER take more than about four at a time unless you know an extraction method because tylenol is dangerous even fatal in large amounts. I personally never take any more than 4 hydro's at once, which is still 2000mg tylenol(quite a bit). Oxycodones are usually name brand Percocets and quite stronger but still with the tylenol or maybe aspirin I think. All of these are addictive and shouldn't be done very much. Also, even though some people will claim up and down darvocet will do nothing for them, it is part of the family and will give a slight buzz, and is relatively safer than the rest.
