We have plenty of ideas. The most obvious one is to begin controlling the areas of the border through which these drugs are entering the country.
Unfortunately that would require an admission by the current US administration that there is a catastrophic crisis at the southern border - one encompassing human, financial, drug, cartel, Chinese, terrorist, human trafficking, and a myriad of other elements. This harsh admission of reality is a current impossibility for the Biden administration and US Democrats.
And just to be clear, the southern border isn't the only point of entry, but it is the largest and most elaborate. There is an entire industry set up exclusively for opioids. Ignoring the human trafficking, slavery, coyotes, and other elements: just the fentanyl trade alone involves at least two cartels, and an international supply chain that includes India, China, and MexicoS[1][2]. The US would be the fourth sovereign participant in that it facilitates a degree of free trade that would make anyone else incredibly jealous.
