I have been working on an OZ of Cali Pharma since Valentines day. Even in my younger days, a quarter of sensimillia would last me a month. My buddies would buy an OZ of the cheap stuff...colombian, mexican, etc and it would be gone in a week.
I have always bought the very best I could get my hands on and leave the lawn clippings to the kids. I guess a good parallel would be comparing a 5th of 15 year old, single malt scotch to a case of beer.
