It had a lot of negative consequences for me. It was harder to see the sometimes. Where alcohol might leave me passed out on the bathroom floor or in the hospital, weed never did that.
But it DID keep me from enjoying life. I was chained to it. It made me anxious and less productive and it was my number 1 priority. I didn't even want to spend much time with family members if I couldn't smoke weed around them. And the list of things I sarificied goes on and on.
It took some time for me to adjust and for my brain to heal from the years of alcohol, pot and other random drugs, but now I feel better than I ever did when I was smoking weed. It's been worth it to quit.
