Less than two weeks ago, a massive car fire in Lake Worth may have been caused by people mixing meth in the back seat -- called a "shake and bake" because the meth is typically mixed in a plastic bottle and simply shaken.
Five people inside the car suffered burns, and the investigation continues.
The Tarrant County Narcotics Unit now sees nearly one "shake and bake" case every month.
"As we know with other meth labs, they've always been volatile," said Ronna Huckaby with the Recovery Resource Council. "Now it's going to be in a smaller quarters, people are going to get burned and unfortunately, people are going to get killed."
Drug counselors are seeing more people addicted to methamphetamine made in small batches.
"The more accessible, the more cases that we see," said Judith Alexander Priest with the Recovery Resource Council in Fort Worth.
Methamphetamine made in Mexico remains the biggest problem here in North Texas, but drug counselors say backseat batches are becoming more common and more dangerous.
"The ingredients can get mixed up you're not having to regulate the dosage so anything can be different with an individual and therefore its extremely dangerous," said Priest.
The Recovery Resource Council offers a wide range of services to help people overcome addictions.
