I just got some mushrooms from a friend I have no idea how many grams it is and i dont have a scale. Can anyone eyeball it and take a guess about how many grams I have? How many should I eat for my first time? I dont want to miss out on an opportunity to trip on shrooms just because I cant weigh it. Any tips for first time tripping? I plan on tripping at home so I'll have a safe environment to trip at.
