Crack Cocaine - Female ( Maybe borderline "crossdresser"? , "She" is sexy and hot as hell but aggressive and just plain crazy... hmmm)
It's funny you say that because one of the street terms for heroin is boy, whereas coke is girl. But I agree, there is something feminin about opiates, as it's such a gentle euphoria. Though I don't want to start spreading gender stereotypes here.Opiates are definitely of a more female essence. As for other drugs, I cannot say.
