What is the ruling on accepting a gift (e.g., bread) from money whose source is hashish cultivation?

Money earned from trading hashish is illicit money, and it is not permissible to accept a gift bought with it if the source of the money is known, whether it be food or anything else. If all of the giver's money is unlawful, then accepting his gift is forbidden if it is known that the gift was specifically purchased with unlawful money.
