I have been making an excel sheet with my consumption. Since i don't have a scale, i asked someone who has one to weigh a full contact lenses case full of ABV. I know it is not exactly accurate but i can infer a lot from my usage this way.
ABV weight of a full lenses case is 1g exactly. According to Fred, who has done a great study on weight loss of ABV compared to fresh and the results varied between 25 to 30% difference.
So i assumed the weight of the fresh herb would be 1,3g.
Since 01-06-2012, about half year after i started vaping for the first time, until now 8 months later, this is what i have found in my usage:
WEIGHT:
- Estimated Total Weight (g): 22,1g
- Daily Weight Average (g): 0,092g
- Maximum Daily Average (g): June - 0,26g
- Minimum Daily Average (g): July/September/November/January - 0,04g
- Monthly Average (g): 2,76 g
COST:
- Average Daily Cost (€, at 8€/g): 0,74€
- Maximum Daily Average (€): June - 2,08€
- Minimum Daily Average (€): July/September/November/January -0,35€
- Monthly Average (€): 22,1€
Notes to some potential outliers: June was particularly wastefull compared to all the others with 2x-6x the amount i vaped in the other months. OTOH, i saved a bit on summer months due to supply constraints i was forced to ration it a bit.
