Straight out of the addicts playbook. Former stoner of 10 years, I see the excuses. Needing drugs to walk through life is like needing a crutch. You are not stronger with them, they are an inhibitor to your natural greatness.

"I don't need drugs, I want them"

Desire, when the pattern holds, becomes need. I used to think "yeah stopping weed is easy," then would spend all the time in-between thinking "this situation would be so much better with weed." So much so that I did absolutely insane things to get hold of it while I was living in China. My desire was very much in the realm of need, but I always made excuses to myself and my loved ones.
