Drug addicts and their organs....

I use the search button but could not find an answer to this question, if I missed it, I apologize...


Anyway,

My question is this: If an individual dies from a drug o.d., are the organs still viable for immediate transplantation??.

Even if this person's system is loaded with lethal doses of illegal chemicals?
Can the transplanted organ, s/a the heart, kidneys,liver have a detrimental effect in the new patient.



Thanks.
