Less than an ounce of weed per month for five years. Then an ounce of weed per month, every month, for another 5 years. Two six month breaks. One three month break. Coughing up black stuff from my lungs wasn't unheard of.

I had genuine concern about the damage I was doing to my lungs and brain, so I started trying to quit more seriously about two years ago. Two of the six month breaks occurred in the last two years.

I've smoked maybe a gram in the past month.

I strongly feel that I should not be a shining bastion of good lung capacity.
