The addict cannot sit with pain. The addict does not buy things to use them. The addict buys things to feel a change in state.
This is the law that governs compulsion, the pattern that explains why smart people make stupid decisions over and over again.
The temporary high is always chosen over the long-term health. Always. The addict knows the maths. The addict can see the trajectory. The pattern is identical. Only the zeroes change.
