How many 30 mg Sudafed tablets can a 35-year-old customer purchase at one time?

In determining the quantity of 30 mg Sudafed tablets that a customer can purchase at one time, it is important to consider regulatory guidelines regarding the sale of pseudoephedrine, which is the active ingredient in Sudafed. In the United States, laws restrict the amount of pseudoephedrine that can be purchased by an individual in a single transaction to prevent its misuse in the illegal production of methamphetamine.

According to the regulations, a customer can typically buy up to 3.6 grams of pseudoephedrine per day. Given that each 30 mg tablet contains 0.03 grams of pseudoephedrine, the calculation for the maximum number of tablets allowed involves dividing the daily limit by the amount of pseudoephedrine per tablet.

3.6 grams (the maximum daily limit) can be converted to milligrams: 3.6 grams = 3600 mg.

Now, dividing this by the 30 mg per tablet:

3600 mg / 30 mg per tablet = 120 tablets.

Thus, a 35-year-old customer can legally purchase a maximum of 120 tablets of 30 mg Sudafed in one transaction, in accordance with federal regulations.
