ANYTHING THAT IS DONE OUT OF HABIT CANNOT BE A GOOD THING.
THEREFORE, ADDICTIONS ARE EVIL. WE CAN DEFEAT THIS EVIL BY GIVING A PERSON SATISFACTION WITH WHAT HE DOES, THE SENSATION OF A FULFILLED LIFE. THEN HE WON’T NEED TO CUT HIMSELF OFF FROM LIFE.
BUT IF HIS ENTIRE LIFE CONSISTS OF ENDLESS SUFFERING AND EMPTINESS, THEN WE CANNOT BLAME HIM FOR OPTING FOR DRUGS. -Rav Michael Laitman
