Generally speaking DHS takes the position that there is no bond available to a person with a drug conviction (assuming that he was arrested or otherwise incarcerated on that charge any time after 1998). However, a number of federal courts have held that a person with a drug conviction must be given a bond hearing if he was not taken into custody by DHS immediately upon his release by the government on the drug charges.
It sounds like a mandatory detention case, in other words no bond will be issued but it's impossible to provide exact advice without meeting with the person and reviewing their paperwork. A "minor" drug and distribution case, is not in fact considered minor by immigration, it will most likely be argued that it is an aggravated felony, which has severe immigration ramifications. Your friend needs an immigration attorney ASAP.
