Several things.
My first time with MJ, I didnt notice anything at all.
Adequate dosage for them might not be the same for you
This will sound weird at first until youve done it a few times, but Since youve never been high, you might not know what youre looking for. Different weed gets you high in different ways and there is no criteria of "This is how youll feel when youre high"
Depends on what strain the edible was made with. If I have pineapple express, I cant tell that Im high unless I work on a project. Then I notice that my focus ability is super intense, otherwise, no one would know that I was high and neither will I. I can take Headband and immediately feel the head high or Jamaican Diesel and feel the sexual high.
Depends on your environment. Sometimes If I consume by myself, it doesnt seem like Im high but If I have that same strain in a group of friends Ill be super high and have a great time that enhances the moment. A lot of times if I consume alone, I never feel high so thats why I rarely do it alone. Sometimes ill consume with friends and itll be like "whatever" the whole night and ill just zone out..
My second time started with MJ, I had smoked a full bowl to myself, i didnt know what it meant to be high until i had a strain where I REALLY felt it... First i finally noticed that my legs were bouncing uncontrollably, then I noticed that I could hear EVERYTHING crystal clear, even the people having a conversation in the backyard and next door of the house i was at.
Sometimes if i eat an edible and have certain foods, it numbs the effects.
