I smoked cigarettes and weed for twenty years. People say weed isn't addicting but I needed it to feel "normal" until it started making me more anxious.
I replaced these with other things off and on, like energy drinks for cigarettes then later beer for weed.
Now I don't use any but what I came to realize was my addictions were a replacement for not feeling love and being in love.
Addiction is anything you love doing more than life itself because you don't necessarily like your life.
