As drug enforcement authorities continue to sound alarms over the effects and accessibility of synthetic drugs, courts are struggling for consistency in dealing with substances whose popularity have outpaced the legal framework around them. The result is a sentencing process thats often bogged down by complex science and can yield uneven results in different courtrooms around the country. (AP Photo/Dale Wetzel, File)
