There is no universal answer to how much hemp-derived Delta-9 you should consume. If it’s your first time trying edibles with Delta-9 THC from hemp, do not eat the entire “unit.” For example, if you are trying gummies or edible for the first time, you should not eat a whole gummy or edible. Instead, cut it up into smaller pieces, see where it takes you, and then decide where you want to go from there.
