you gotta understand something... wc been rappin for a long long time. back in the 80s, the crack cocaine problem got so bad, that rappers took it upon themselves to speak out against drugs in their songs. people like queen latifah, krs one, public enemy... and lots of others. some of which were ACTUALLY DOING DRUGS! but the point is, in those times, if you had came out talkin about smokin weed or slangin drugs in a glorified sense, it would have been suicide. it was basically just the trend of that time. say no to drugs. you had lots of niggaz talkin about:
"dont smoke weed or cess, cuz its known to give a brotha brain damage"- dr. dre
"dont smoke buddah, cant stand cess"- rob base/dj ez rock
i think wc said some shit like that too. i think he even said something about not being a gangbanger... but its just what you had to do at the time to get over.
