Drug and Substance Abuse

Why drugs?
“Life as we find it, is too hard for us; it brings too many
pains, disappointments and impossible tasks. In
order to bear it, we cannot dispense with palliative
measures: powerful deflection, which causes to make
light our misery; substantive satisfaction, which
diminish it; and Intoxication, which makes us
insensitive to it.”
- Freud
