Bumping an older thread here but I have been thinking about the morality of illicit drugs, namely marijuana and cocaine. Since there has been no definitive Church teaching on those two drugs in particular, I would equate their sinfulness with that of drunkenness as "loss of reason", among other things, seems to be why some consider said drugs mortally sinful. I have read that there are three degrees of drunkenness with only the third being mortally sinful, unless circuмstances render the first and second mortal. They are;
First Degree: Reason becomes slightly disturbed
Second Degree: The disturbance extends to the bodily organs
Third Degree: Complete privation of the use of reason
The signs of the Third Degree: inability to distinguish between good and evil, forgetfulness of what one has said or done while drunk, an unusual or foolish behavior
Now I do not use marijuana or cocaine, but to the extent of my knowledge neither (used in moderation) leads to a complete privation of the use of reason. Does anyone have thoughts on this, or traditional teaching regarding these drugs?
