CMEA limits the quantity of pseudoephedrine that can be purchased by an individual customer. The limit is 3.6 grams at one time and a 9 gram total over a 30-day period. Limits may be different for mobile vendors or for mail orders. For example, only 7.5 grams in a monthly purchase may be by mail order.
