Well I mean barring your personal dislike of the source, it does report an objective fact: opium cash crop farming exploded under the US / Joint alliance occupation and decade+long anti insurgency war, and died out once they left.
And this objective fact DOES raise important questions: what in the hell was the US doing all this time? They had infinitely more resources than the Talibans do now to subsidize non opium crops for farmers, to encourage diversification and development, etc. Did they turn a blind eye to the mass scale poppy farming? If so, why? It generated huge sums, was it a strategic use of and encouragement of corruption of local Afghan administrators and tribal elite to "make the occupation easier"? Did some money return to western elements? What was the impact on world trafficking?
Like you can dislike mintpress news but IMO it's important to, now that the US/West occupation of Afghanistan is over, not swipe it all under the rug and investigate.
