meth bugs
n.pl.— Note: Similar to cocaine bugs. «“The skin starts to dry out and becomes itchy and the user starts to hallucinate and thinks he has something crawling under his skin—what is commonly called meth bugs. Because he thinks something crawling on him, he starts picking at his skin. That’s where the sores come from,” he said.» —“Methamphetamine: A hard habit to break” by Ida Brown Meridian Star (Mississippi) Jan. 28, 2008. (source: Double-Tongued Dictionary)
