Our expert says:
This is too little information to comment on really. It sounds like there are two problems: the substance abuse/dependence (which most certainly can impact negatively on sexual function) and inability to ejaculate...this could be seperate (there is a condition called male orgasmic disorder where some men cannot ejaculate intravaginally) but it could also be linked to the substances. Deal with the substances first and sexual issue after.
