The No. 1 reason why Trump’s wall won’t fix the drug problem

Experts on the drug trade say a border wall, even one as big and beautiful as Trump promised, would be near-impotent in stemming the supply of illegal drugs. The primary reason? Drugs that flow across the Southwest border, like heroin, are primarily transported through existing border checkpoints via cars and trucks. Those checkpoints will be there whether the wall gets built or not. Mexican drug cartels “transport the bulk of their drugs over the Southwest border through ports of entry (POEs) using passenger vehicles or tractor trailers,” the DEA writes in its 2015 National Drug Threat Assessment.
