But is it legal to buy medications from Canadian pharmacies? The answer is, technically no, but U.S. officials are allowing it to happen.
Under the Prescription Drug Marketing Act of 1987, it is illegal for anyone other than the original manufacturer to bring prescription drugs into the country. However, federal officials have decided to exercise "enforcement discretion" in dealing with prescription drugs brought across the border, provided the drugs are not narcotics or other controlled substances. This means that as long as a person brings back no more than a three-month supply for personal use, border officials generally look the other way, Thomas McGinnis, director of pharmacy affairs for the U.S. Food and Drug Administration (FDA), told the Milwaukee Journal Sentinel in March 2001. Patients generally may order refills in amounts up to a three-month supply without interference.
What about ordering over the Internet? Prescription drugs cannot be legally mailed into the United States by foreign "e-pharmacies." But here again officials are employing "enforcement discretion," preferring to use limited resources to crack down on large commercial drug supplies and narcotics, not prescription-drug shipments for personal consumption. Thus, customs officials allow the companies to mail up to 90-day supplies of medications.
