How long does it take yall to plow through a gram of shatter or other concentrates that can be placed in a banger ?

I bought 1g of shatter a month ago in prepration for winter. It'll be too cold to go on joint walks so thowing some shatter in a rig seemed like a nice discreet way of smoking and staying warm in my home.

Since buying it , when i look at what remins it feels like i can smoke on it for atleast another 2 weeks.

My routine is 3 hits before bed and all day on sat-sun .
