I always keep a stash of 2:

I buy about a 1/4 Ounce (7 grams) of mids at a time and I'll smoke that if I'm limited on time. Say my parents are coming home in 2 or 3 hrs and I want to be strait when they get home.

I buy highs about 1/8 Ounce at a time and save this for days when i have the house to myself or if I'm just planning on blazing for a long time.

Fuck Schwagg, might as well smoke resin or legal herb
