there is an actual strain of marijuana called white widow which actually grows naturally. people can LACE it with crack, SOAK it in LSD, but the plants do not grow naturally with crack or LSD. watever myths you heard about it having crack in it would have been personal stories about people who've gotten it from dealers who lace shit. no natural plant could just grow with crack in it, and people dont "make" purple haze or else how would they sell seeds for it? pot is pot, and nothing else unless laced. thats all there is to it.
