Someone slipped something into my drink causing me to puke foam i have reason to believe it was c4 extreme, can it do that to someone with bad acid?

Doctored drinks: First, anything and everything is possible when their drinks get "laced". Second, reportedly "safe" food supplements often come with "additives" intended to "hook" the user by the "extras"--in the case of C4 it's dmaa, a very dangerous drug for unsuspecting victims--and a cause of death. Women (and men!) exposed to such criminal behavior should find somewhere else to pass their "leisure" time.
