Switch up your method in a more significant way.
The highest I have ever gotten was a combination of a couple canna-caramels and then a couple small puffs off a joint right when the food started to set in. I was just FLOORED at the strength of the high from the combination of smoked + eaten MMJ products. Not like you probably want to know the gory details, but I was desperate to kill the pain from a particularly bad round of girl cramps. OW! It worked... and then I stopped walking around and made the mistake of sitting on something comfortable... zzzzzzzzzzzzzzzzzzzzzzz.....
