Afghan opium isn't going anywhere. The Taliban themselves are the biggest money-maker off of the opium trade. This is just them trying to assume control and prevent anyone else from having a stake.
In July 2000 the Taliban enforced a ban on poppy farming via threats, forced eradication, and public punishment of transgressors. The result was a 99% reduction in the area of opium poppy farming in Taliban-controlled areas, roughly three quarters of the world's supply of heroin at the time.The ban was effective only briefly due to the deposition of the Taliban in 2001.
