right weed does get laced with other drugs so that they can try and get them hooked on stronger stuff but as for the sugar thats more like it in this case if the bud tastes shit coz either they have not flushed the system befor harvest it makes ur weed taste like shit so they put summing sweet in there to help with the taste. i no about the laced drugs ting coz my ex dealer/friend does it him self i dont condone it but hey what can u do. well thats my two pence laters all peace!!
