I get the sentiment of this but it's false. Only alcohol produces dts. Only alcohol and benzodiazapines produce deadly withdrawal. The rest is pure mind over matter.
I'll close on this and not aimed at you. If you believe addiction is real them the power of choice is gone, the craving for your drug of choice will consume your world. To deny addiction in this day and age is laughable, the ones on here quizzing it are either abhorrent racists or stay in a closed world.
Again. Come and see the work we do, come and see the despair, remorse, shame and hopelessness of these people. Do use a world of good. God forbid you ever have 1 in the family
