@ErikUden If someone hasn't tried an edible before I would suggest not consuming more than 5 mg THC. Current strains of marijuana may have concentrations of THC of 20% or greater. So if your 1/4 cookie had 0.1 grams of marijuana that would be 100 mg. At 20% that would mean you consumed 20 mg of THC. There are also many different strains. Some people prefer strains that have equal (and lower) percentages of THC and CBD. One example is a strain called Harlequin which has about 12% CBD and THC.
