With as much coffee and soda as I drink I decided to do some research, here it is. See kids? I make science suck even more! Caffeine Chemical compound: C8H10N402.
"There are about 100 mg of caffeine per cup of coffee", (4oz cup?). "Instant coffee generally contains less caffeine than coffee prepared from ground beans". "Caffeine is a white crystalline and shiny powder with a melting point of 236° C and is a weak base"."Very few deaths have been reported by its use and probably when used in excess of 10 grams. The blood lethal level are probably in excess of 15 mg percent"."Caffeine withdrawal may cause headache, nausea, depression". Duh.
I stole this information from a couple of websites.
