Zambia #
Diphenhydramine is a controlled substance in Zambia and the US State Department warns "The Zambian Drug Enforcement Commission (DEC) has detained a number of U.S. citizens for possession of antihistamines such as Benadryl and other over-the-counter medications, which contained small quantities of diphenhydramine, an active ingredient that is on Zambia’s list of controlled substances. Although unaware of these restrictions, U.S. citizens have been charged with drug-trafficking offenses, had their passports confiscated, and have been jailed. " (thanks l) (last updated Oct 23 2013)
Diphenhydramine is sold over-the-counter without prescription in most countries where it is available. Zambia stands out as a country to avoid bringing over the counter medications to.
