Superman is far stronger than the common man in his physique, but what about in his psyche?
Today is International Day Against Drug Abuse, and as we know it is quite hard for a common person to conquer the addiction by his/her own will. So I'm curious:
Can Superman be affected by drugs, such as heroin?
If yes, can Superman be addicted to drugs?
If yes, does Superman have a sufficiently strong will to conquer the horrible addiction by himself?
By Thaddeus' answer in this question we know that Pre-Crisis Superman was immune to narcotics when be under a yellow sun. However, under a red sun, he appeared to be Human in all the ways that mattered. So whenever under a red sun, what's the answer of these three questions above?
