We've had a lot of these questions. If you try the search function before posting you can find lots of good useful info that has been posted, debated tried tested and true.
Anyhow, as was mentioned cannabinoids are fat soluable. I am assuming you are choosing to use milk and peanut butter on your cracker to release the active ingredients from the weed.
Well, the reason people make butter from their weed is so that they can enjoy the different effects while not consuming some of the componants that will add nausea, as well as unnecessary organic compounds.
My point is, why concoct a sorta kinda recipe and then still consume the undesireables?
The effects you will get this way from 1.5 will not surpass the effects you would get from smoking it. It is an inefficient method and a tiny amount to start with.
Try making some butter. I can smear a dab on a cracker and get exactly the effects I seek with no unpleasantness.
Those who will say that this is a good way to make a cannabutter snack have never had true cannabutter. Believe me, there is no comparison.
You can make the butter once you get yourself a bag of bud or even shake and have some at the ready.
As for your 1.5 g , I would say just smoke it.
But some folks have to try for themselves to know what others have already learned.
Either way, have a good one.


peace.
