For each cookie I feel effects after 2 hours, not strong, so I work backward from when it'll be okay to be 'high'.
(When Hubby, adult dependent kid and elderly Mom don't need me anymore that day.)
I have found that these cookies made with hash and butter takes 2 hours to kick in and only lasts about 20-30 mins. So if I wish to maintain, I need to eat/take one every hour. There is a minor amount of overlap when I take one every hour but never enough to feel bad effects. That's with my Afghan Auto, don't know what a different variety would be like.
And I know when the effects wear off 'cause my forehead gets chilly and my mind is not 'floaty' anymore. LOL
