from my experience, issues with edible cannabis are almost always caused by too high dose.
Even newbie is able to really enjoy it, if the dose is right.
I recommend to NOT eat it in a tasty food, so no brownies. Other form, which does not hide the taste, is better.
Unexperienced users are not so tempted to eat too much then.
To eat some brownies of unknown strenght (most likely prepared by some chronic cannabis user with high tolerance) in a party could be like to drink 1 liter of alcoholic beverage. If it is a beer, then ok. If it is a strong 50% spirit, then you have a problem.
I prefer very concentrated infused oil, like olive oil, which can be dosed by drops.
Of course, your digestion needs to be activated by some food.
