Drug enforcement officers are seeing a rise in small-scale methamphetamine production.
So-called 'one-pot' meth labs may produce less than larger operations, but they still carry the danger of fire and explosion.
Earlier this week police responded to one such lab along the Connecticut River in Hinsdale.
"We are seeing a growing amount of one-pot methamphetamine production here in the state," says Jon Delena, a DEA special agent overseeing New Hampshire.
Delena says road crews often come across these compact labs as the snow begins to melt and that smaller examples produce a couple of grams.
"Although we are in the middle of -- as everybody knows -- an opioid epidemic, we can't ignore other drugs, such as crystal meth,” says David Mara, the Governor's Advisor on Addiction and Behavioral Health.
For the past three years, the state police forensic lab has seen a steady increase in the number of meth cases, which more than doubled annually to 834 in 2017.
